7 Easy Steps to Secure Your Wireless Router

2008-05-26T06:11:00.000-07:00

Accessing Your Wireless Router's Configuration

To gain access to your wireless router settings and configuration menu then connect to the router either wirelessly or via a Ethernet cable. Open a web browser and type either:

<a href="http://192.168.1.1/">http://192.168.1.1</a> or

<a href="http://192.168.2.1/">http://192.168.2.1</a>

1) Change Admin password

Most wireless routers ship with a blank password. It is essential that this is changed else a potential hacker could get into your router configuration and lock you out of your own hardware.

2) Change The Network Name (otherwise known as the SSID)

The default network name is usually made up of the name/model of your wireless router. This information gives a head start for a hacker and makes it easier for them to break into your network. Don't rename it to something like your surname or house name as this unnecessarily exposes personal information. Rename it to an alpha-numeric string - this can be up to 32 characters long.

3) Turn off SSID broadcasting

By default, a wireless router's SSID is broadcast so anyone in the vicinity of your wireless router can see that it. SSID broadcasting can be turned off thus making your wireless router virtually invisible.

4) Enabling Encryption

This is switched off by default. There is a choice of WEP, WPA and WPA2. Currently the latest encryption method is WPA2 so use this where possible. Both your wireless router and wireless PC adaptor must be configured to use the same encryption.

5) Mac Address Control

All hardware has a unique MAC address associated with it, including your PC adaptor card. This MAC address can be added to access control list in the wireless router. Only devices added to the router's access control list are allowed to be connected.

6) Update router firmware

It is recommended that the latest router firmware is downloaded from the manufacturer's website and installed in the router. This will hopefully fix any bugs that have been found for your router and also help with any known security flaws in the router itself.

7) Backup settings

Finally, backup all router settings. If you reset the router back to its factory default settings for whatever reason, your configuration can later be easily and quickly restored back into the router.

Wireless Laptops Make Networking Easier

2008-05-09T23:26:00.000-07:00

Laptops have entered the arena of computing in the twenty-first century and brought about a mammoth change in the outlook of all sectors that made use of computers for their working. For example, corporate organizations which used personal computers earlier now use laptops for mobile transactions and easier functioning.

A business delegate no longer needs to sit in front of his personal computer and waste his time. He can carry his laptop around with him and work as he travels. This way, laptops have brought about a new dimension to the outlook of Industrial Technology. Recently, laptops have also been introduced into more complicated setups like computer networks. This involves connecting a laptop to a home or office network for easier data transfer and synchronization. Most organizations operate using a network where many computers are connected together to co-ordinate and modularize work. In such a scenario it would be really helpful for a laptop to be connected to the network so that in an emergency, the laptop can just be taken around without any loss of data. More specifically, the possibility of making the connection a wireless one brings about a significant improvement in the advantages of using a laptop in a network.

Most laptops come with the provision of supporting a wireless network. The support needed for a wireless network is called a PCMCIA card or an access point that serves as a bridge between the laptop and the existing network. These components are simple to understand and can be easily installed by the user himself. Once the PCMCIA card or the access point has been installed, the laptop can be taken anywhere within the range of the access point and still remain connected to the wired local network. If the local network is connected to a WAN like the Internet, then the laptop too, can enjoy all the features of the Internet and behave as though it were connected to the WAN itself.

The advantage of having such a wireless connection can be realized only by experiencing the comforts it offers. For example, a wireless laptop connected at home allows the user to roam all around the house carrying the laptop in his hand, without breaking connection with the network. In the office, one can work at his desk, then carry the laptop to the dining area and work over lunch without forsaking the network connection. These connections are achieved by low power radio signals which are the basis for the wireless network connections. You can find out more about gaming and wireless networking at http://www.topgaminglaptop.com

The wireless setup is achieved by installing a Proxim Skyline 802.11b network card to the laptop. A Proxim Skyline 802.11b Wireless Broadband Gateway is also connected to the existing wired Ethernet LAN as a bridge. Using this setup, the notebook i.e. laptop can be moved anywhere within range of the network card while maintaining connection with the local area network. Another component here is the access point. An access point is basically a radio receiver and transmitter that is connected to a wired network. They are independent of the operating systems and work perfectly with all versions be it Windows or Linux or MacOS.

Mobile Computing - The Growing Technology

2008-04-26T21:39:00.000-07:00

Technology that evolved in the 90's is bringing two important changes that will reshape the existing network computing into what is becoming known as Mobile Computing.

Mobile computing is the concept of being able to connect to friend's family and the office at any-time and any place and having full access to information and resources. If you were to consider the Web as today's biggest, distributed information system it would be only natural to add mobility to the web. Over the last several years lot of research and developments has taken place to provide for a "mobile web". Mobile computing is one of the hottest development fields today. This has become apparent with the boom in the smartphone industry with developments like the I-Phone and the N95. Mobile computing is not totally new and has been around for quite some time now and has been accessed through the smaller PC's and PDA's For many years now.

It has not been until recently the full power of the internet has been available in a mobile format though. Today you have many options for connecting and accessing information through the internet or even through your own unique network configurations. You now can truly be connected where ever and when ever you need to have instant information. Mobile computing is no longer a "scaled-down" version of the networking capabilities.

As wireless communication continues to boom media and the mobility of computers will create new problems in networking, operating systems, and information systems. Both hardware and software will be going through some rapid and amazing changes. Keeping up with the wants and needs of the Mobile computing population will keep this area of technology on its toes for years to come.

These technologies will dramatically changing our day-to-day lives, with the popularity of small devices such as (PDAs) personal digital assistants and the smartphone we now have the internet at our finger tips 24 hours a day.

Reducing the energy consumed in using these devices, will be and is currently being look at as the next big challenge. The need to extend the lifetime of the batteries that power them is one major concern and along with reducing their weight will be major design advancements in these systems. Mobile computing has increased from around 25% in 1998 to well over 65% in 2008 and the trend seems to be heading to even more growth over the next few years.

Get the Highest Speed Out of Your Wireless Computer Network

2008-04-13T07:09:00.000-07:00

When it comes to a wireless standard, the first thing we all look at is how fast will this baby run! And you know the trade-offs, you can spend a lot of money to get the fastest thing running, or you can back off a little and save a lot.

The good thing about wireless networks is that the price difference between wireless standards is almost gone. There are some things that could add up, but I will explain the difference and why you might want to go that route or not.

Now, let's get to the different wireless standards you can choose from.

1. 802.11b - 11Mbit at 2.GHz 2. 802.11a - 54Mbit as 5.0GHz 3. 802.11g - 54Mbit at 2.4GHz 4. Hybrid Systems

When you get ready to purchase your equipment, you will see a lot of systems saying that they are faster than these standards listed above. Most will say 108Mbit per second, some 125Mbit per second and a few even higher. To operate at these speeds usually requires you to only use their network cards to access their access points, some of them require a specific card from them to get that speed. If any other card connects, then they will drop back to the standard speed and you lose the extra speed you probably paid extra to get.

What Should You Get

I was purchasing equipment for a completely new wireless setup. We only had one older wireless computer and I replaced the card in it with a new one. I did purchase a system that advertised the 108Mbit speeds since I knew who was going to connect to it.

If you are building a new network setup, I suggest you purchase a system that will run faster than the standard, but only if you know who is connecting. If not, then get a system that runs on the 802.11g standard. The price is about the same as 802.11b but runs 5 times faster.

Obstacles entangle wireless networks

2008-02-08T17:29:00.000-08:00

SAN FRANCISCO -- The same forces slowing development of single- city wireless Internet networks using Wi-Fi technology are now overwhelming their super-sized counterparts that cover thousands of square miles and scores of municipalities.

A telling example can be found in Silicon Valley, where plans to provide free, high-speed wireless Internet access to 42 cities in an area of more than 1,500 square miles have come to a standstill, says the person in charge of the effort.

It was once thought that municipal Wi-Fi networks of all sizes could be supported through the sale of advertisements that appear during the free Internet sessions and the small fee paid by those who want a faster, ad-free Internet service.
However, many cities with their own wireless networks say there's been little demand for their premium services, plus technology issues have limited the networks' reach. And while businesses were willing to buy advertising on these single-city networks, they complain about receiving little returns on their investment.

Given that the regional networks share the same business model, doubts have spread. Businesses once willing to fully fund such projects have had a change of heart and want substantial help from other partners. Those trying to create regional wireless networks are being forced to rethink their options midstream.

In the case of the Silicon Valley Wi-Fi project, planners are contemplating asking cities to share the upfront costs. A worst- case possibility is scrapping the project altogether.
"We are working now in a new paradigm; we understand that," said Russell Hancock,chief executive of Joint Venture: Silicon Valley Network, which vows to continue building the network despite the rising odds against it.

The trouble for regional wireless networks was foreshadowed about six months ago, when the business model behind city-wide networks began crumbling. EarthLink Inc. recently retrenched its plans to build wireless networks in a dozen more cities, and struggles have arisen in places like Minneapolis, where similar networks are already up and running.

Joint Venture: Silicon Valley Network, the nation's biggest proposed region-wide wireless network, was introduced about two years ago. Hancock said he once hoped to build a network by 2008 covering 1,500 square miles and encompassing 42 municipalities.

Under the present conditions, that's not going to happen, he said.

"Now, I just don't know," Hancock said.

Now it appears that backers International Business Machines Corp. and Cisco Systems Inc. have had a change of heart, Hancock said. Both are supporting the region-wide effort with a commitment of up to $150 million for construction, but the two companies now want the municipalities involved to provide some kind of financial commitment to the networks, he said.

"They said, 'Look, we've changed our mind; we won't build it under these circumstances,'" Hancock said. "They completely want to go forward with the project, but not under this model."

Cisco spokesman Neil Wu Becker said, "We are definitely not removing ourselves from this project and remain committed to making it a success."

An IBM representative didn't return a phone call seeking comment.

Hancock's been on a road show of sorts to deliver his message to the heads of the 42 cities that want to be part of the Silicon Valley project. A wide array of options are now on the table -- from radically altering how the effort is funded to shelving it altogether, he said.

A NETWORK OF A DIFFERENT STRIPE

2008-01-12T10:21:00.000-08:00

Zebras go wireless on the Kenyan plains.

IT WAS PRETTY PATHETIC," recalls electrical engineering student Pei Zhang, describing the scene. In the middle of the Kenyan plains, three Princeton University professors and four Ph.D. students-Zhang among them-all hovered over a metal box, waiting for a green light to flash.

But this was more than an ordinary LED. It was the culmination of three years spent developing and testing a wireless network like none attempted before: a network of computers carried in collars worn by wild zebras. Backed by a $1.3 million grant from the National Science Foundation, Princeton's ZebraNet project sought breakthroughs in two rather disparate fields: zebra behavior and wireless sensor-network computing.
ZebraNet wouldn't be able to advance either field unless the little green light glowed, showing the first communication between the base station in their hands and the computer that had been wrapped around a zebra's neck that morning.

With the zebra in sight, the seven academics anxiously watched the metal box. The light remained dim. Then, finally, a beam of green light appeared, and the group erupted in cheers. The startled zebra took off at a gallop.
Since that first glimmer of success in January 2004, ZebraNet has accumulated an impressive list of accomplishments. It has overturned long-held ideas about zebra behavior. It has met the ambitious goal of creating a wireless network of computers that can process position data and communicate with GPS satellites, a base station, and each other-all powered by a small bank of solar cells rated at 0.4 watts per computer. It has proven the potential to wirelessly update software on a network using peerto-peer communication. And perhaps most importantly, it has challenged a group of graduate students and their professors to take their research out of the laboratory and into one of the most demanding field environments imaginable. "Engineers spend a lot of time inside in a lab," says project leader Margaret Martonosi. "This was a once-in-a-lifetime opportunity."

The project grew out of electrical engineer Martonosi's work with portable, low-power computers. In one senior thesis project, her students developed a system for GPS-enabled Palm computers to give an automated tour of the Princeton campus, with information provided according to the user's location.

Princeton zoologist Dan Rubenstein, an international authority on zebras, learned about the automated tour and immediately saw possibilities for his own research. Before ZebraNet, Rubenstein had monitored zebra movements by learning the stripe patterns of individual animals and recording sightings. Other biologists use VHF collars that emit a "ping" signal to track large animals. A researcher takes several readings with an antenna and triangulates those readings on a map to home in on an animal. "It's slow, it's not particularly accurate, and it's very labor intensive," Rubenstein says.

Rubenstein and Martinosi wanted ZebraNet collars to collect GPS readings several times an hour and to store the readings in flash memory. Even more amazingly, they wanted two computers to be able to swap data whenever one collared zebra came within a kilometer or so of another one. This would mean that if a researcher could find just one collared zebra, he could wirelessly upload GPS data from several zebras. In the same manner, the researcher could perform a software upgrade to the entire system simply by getting within range of one zebra. This capability is essential, says Martonosi, "because it's extremely difficult to reboot a zebra."

City ready to launch wireless network

2007-12-30T06:22:00.000-08:00

PLEASANTON -- After Doug Linman mounted a test antenna for Pleasanton's new downtown wireless Internet service, city officials called him to say they couldn't find it.

"Great -- that's perfect," said Linman. "I designed it and painted it 'Pleasanton green.' It matched the pole so well."

Linman, owner of Pleasanton-based Network Anatomy, has been working since January, carefully designing a wireless network system that he says will change the economic balance in Pleasanton.

"People will come into town and spend more time downtown getting their work done," he said. "Farmers markets can get their transactions done over the wireless network. City staff will no longer have to go back and forth writing their reports. Everything begins to change for the better."

The network, set to launch at the end of this month, includes 22 antennas, installed throughout the city's downtown, civic center, senior center and ACE train station areas.

"We have spent a lot of time architecting this network," Linman said.

In addition to mapping potential access points, Linman drove around town for weeks looking at all the different radio frequencies that could possibly interfere with the wireless signal.

"Pleasanton's Wi-Fi network is really clean and free of interference," Linman said.

And, a week ago, Linman put a call out through the Pleasanton Downtown Association looking for testers who reported and would then report back on the service.

"Most other municipalities haven't done this type of testing," he said. "We're getting all this work and detail and science done up front."

Eventually, city staff, public safety officers and the public will be able to access the free wireless service from Arroyo Del Valle to the north, First Street to the east, the Senior Center on Sunol Boulevard to the south and the ACE train station to the west.

Pleasanton is joining other Bay Area cities that have already jumped on the wireless bandwidth. Walnut Creek provides the service in its Civic Center. Concord has had Wi-Fi in its downtown for some time, and a few months ago, officials launched a citywide system that will eventually cover the entirecity. Pleasant Hill has offered free WiFi in its downtown area for a few years.

Elsewhere, free WiFi is offered at the El Cerrito and Martinez libraries, as well as on specially equipped AC Transit buses. And for a short time BART is testing free service at their Embarcadero, Montgomery, Powell and Civic Center stations.

Allen Hammond, Pleasanton's information services manager, said the service, which covers about one square mile, was designed to "keep our mobile workers connected back to the resources that we have in the office.

In the event of a traffic overload on Pleasanton's wireless server, city officials sending or receiving any Web information would have priority over other non-official Web traffic.

In addition to benefits to city workers, having WiFi in the downtown will also be a boon to local businesses, said Christine Salidivar, executive director of the Downtown Association.

"It's much more than people having a cup of coffee and surfing the Web," she said.

"The future will allow for podcasts or a 'ghost tour' on our historical walk."

Broadband Wireless Network Speeds into Stockton and Modesto

2007-12-23T03:01:00.000-08:00

Verizon Wireless Gives Customers Access to High-Speed Wireless Internet, E-Mail, Mobile Music and More

WALNUT CREEK, Calif. -- Customers in Stockton and Modesto can now access the latest high-speed business and entertainment services on their wireless phones, laptop computers, and other wireless devices thanks to Verizon Wireless.

New capabilities come with the expansion of the company's Evolution-Data Optimized (EV-DO) network, enabling both its BroadbandAccess and V CAST services. Customers in Stockton and Modesto now have access to the same high-speed Verizon Wireless services launched earlier in the San Francisco Bay Area and Southern California.

"Verizon Wireless is committed to expanding our high-speed data network across the nation and is proud to announce the launch in Stockton and Modesto," said Rich Garwood, Northern California/Nevada regional president for Verizon Wireless. "These two communities continue to experience a high rate of growth as so many people make their homes in the area while commuting to jobs in Sacramento and the Bay Area, and vice versa. Now, customers who both live and travel through these areas have access to the true mobility of wireless data."

BroadbandAccess

BroadbandAccess provides on-the-go professionals with full, mobile access to their corporate information as if they were attached to the information via a high-speed wired connection. Users can conduct business anytime, anywhere in the BroadbandAccess coverage area via a secure, true high-speed data connection.
With average access speeds of 400-700 kilobits per second (kbps), users can download a 1 Megabyte e-mail attachment - the equivalent of a small PowerPoint[R] presentation or a large PDF file - in about 20 seconds.

Connecting to BroadbandAccess is easy, using a PC card that slides directly into most laptop computers, through an integrated option on select notebook computers or by connecting a laptop to a BroadbandAccess-capable PDA or phone.

V CAST

V CAST, the nation's first wireless broadband multimedia service for consumers, offers the most comprehensive selection available of music, videos and 3D games on demand. Users can stream video clips (up to 5 minutes long) of the hottest entertainment, music videos, movie trailers, sports highlights, news and breaking weather directly to their Verizon Wireless V CAST-capable phone.

With V CAST Music, customers can browse and download songs from the V CAST Music library of 1.4 million songs directly onto their V CAST Music-enabled phone or Windows[R] XP-enabled PC. They can also transfer music from their PC to their V CAST Music enabled phone and take their tunes with them without a second device.

In California, the company has invested nearly $4 billion in the past five years - part of its $30 billion nationwide network investment over the last six years - to ensure network reliability and expanded coverage, capacity and capabilities.

Coverage

Verizon Wireless was the first national wireless provider to launch a high-speed wireless broadband network commercially in the United States. Verizon Wireless' EV-DO network coverage area now covers more than 150 million people.

BroadbandAccess customers who travel outside the coverage area with an EV-DO-capable device will switch seamlessly to Verizon Wireless' existing NationalAccess network that offers average data transmission speeds between 60 and 80 kbps, with bursts up to 144 kbps.

Built on Ralink chipset, 802.11g wireless networking products leverage MIMO (multiple input, multiple-output) technology, which uses multiple transmitter and receiver smart antennas that send and receive multiple data streams simultaneously. Barricade(TM)g 802.11g MIMO Wireless Cable/DSL Broadband Router, EZ Connect(TM) g 802.11g MIMO Wireless Cardbus Adapter, and EZ Connect(TM) g 802.11g MIMO Wireless PCI Adapter accelerate communication, download, or upload of files.

IRVINE, CA - November 15, 2005 - SMC[R] Networks (www.smc.com) announced today a new line of 802.11g wireless networking products that leverage MIMO. MIMO (multiple input, multiple-output) technology speeds data transmission, improves reliability and increases range of wireless networks by using multiple transmitter and receiver 'smart' antennas that send and receive multiple data streams simultaneously. SMC's staged roll-out of MIMO-enabled products will begin in December with three MIMO-enabled wireless networking products built on the Ralink chipset that can build speedy, long-range, secure wireless networks or extend existing 802.11g or b networks with increased performance: the Barricade(TM)g 802.11g MIMO Wireless Cable/DSL Broadband Router (SMCWBR14-GM), the EZ Connect(TM) g 802.11g MIMO Wireless Cardbus Adapter (SMCWCB-GM), and the EZ Connect(TM) g 802.11g MIMO Wireless PCI Adapter (SMCWPCI-GM).

"The advantages of MIMO are significant," said SMC Networks product manager, Zsolt Mahunka. "The increased reach is a big plus, especially for home networking, where there is often just one access point and users experience dead spots and distance limitations. And, high-bandwidth applications like real-time video and music distribution and gaming are greatly enhanced by the bandwidth and speed increases that MIMO affords. With their backward-compatibility, these forward-reaching products are a great way to build or expand an efficient wireless network."

SMC's first set of MIMO-enabled products provide the speed, coverage, and security that today's demanding users seek. They accelerate communication, download or upload of large files, streaming audio and/or video and a host of other bandwidth-intensive applications. Based on an advanced Ralink MIMO 802.11g chipset, the IEEE 802.11g-compliant SMC MIMO product set enables speedy data transfer-up to 20 times faster than older 802.11b wireless networking devices in MIMO-to-MIMO communication (a MIMO adapter used in its MIMO mode with a compatible MIMO router or access point). At the same time, the products are 100% backward-compatible with standard 802.11g and 802.11b devices-and can even increase performance in mixed-mode (802.11g MIMO and 802.11g or b) networks.

SMC's first family of MIMO-enabled 802.11g wireless networking products will include a broadband router, a Cardbus adapter and a PCI adapter. The SMC Barricade g 802.11g MIMO Wireless Cable/DSL Broadband Router (SMCWBR14-GM) is a platform-independent multi-functional router that combines a 4-port 10/100 Mbps dual-speed switch with Automatic MDI-MDIX feature and a high speed 54Mbps wireless access point. And, wireless connections are secure, with support for 802.1x for authentication, Wi-Fi Protected Access (WPA/WPA2), MAC address filtering and 64/128-bit Wired Equivalent Privacy (WEP), as well as Stateful Packet Inspection (SPI) firewall, network management, and support for Virtual Private Network (VPN) pass-through. The SMC EZ Connect g 802.11g MIMO Wireless Cardbus Adapter (SMCWCB-GM) and the EZ Connect(TM) g 802.11g MIMO Wireless PCI Adapter (SMCWPCI-GM) enable computers and other network-capable devices to connect to an 802.11g, b, or g-MIMO network. Both include SMC's EZ Installation Wizard for quick and easy setup. Simply put the EZ Installation Wizard CD into the PC's CD-ROM drive, click on Install Driver/Utility, and the wizard performs the installation automatically. Then, plug in your SMCWCB-GM into the PCMCIA slot or install the SMCWPCI-GM into an available PCI slot on the computer, and wireless network communication can begin. Both adapters provide a high level of security with support for both 64/128-bit WEP encryption and Wi-Fi Protected Access (WPA/WPA2). Both adapters also include a WLAN utility that scans for all available wireless networks, with profile management that allows users to save names and settings of multiple networks, so traveling connections are easy and instantaneous.

SMC's first MIMO-enabled 802.11g products will begin shipping in December, 2005. The Barricade(TM)g 802.11g MIMO Wireless Cable/DSL Broadband Router (SMCWBR14-GM), will have an MSRP of $139.99; the EZ Connect(TM) g 802.11g MIMO Wireless Cardbus Adapter (SMCWCB-GM), $59.99; and the EZ Connect(TM) g 802.11g MIMO Wireless PCI Adapter (SMCWPCI-GM), $59.99.

Wireless LAN's big payback - Trends

2007-12-02T22:20:00.000-08:00

Without a doubt, wireless LAN (WLAN) adoption has made great strides in recent years in the enterprise market, with many companies already taking the plunge and adding wireless access to their networks. With all the uncertainty surrounding WLANs (specifically regarding security), these early users' experiences can be an invaluable resource for those companies that are still considering the technology for themselves.

For instance, those interested in 802.11 for their workplace might want to know: whether the technology has measured up to expectations; if the investment is paying off, how potential security weaknesses have been handled; and whether adopters are expanding their WLAN investments in 2004.

According to a study conducted by Sage Research, "Wireless LAN Adoption Trends 2004," companies expect any new technology investment to pay tangible dividends. This research indicates that 802.11 networks are yielding real benefits. For many using WLANs, the return is improved workforce efficiency; in fact, 66% cited higher employee productivity as a main reason for installing an 802.11 network. Just as many (65%) have already seen a boost to worker productivity.

Perhaps the most common example illustrating these productivity enhancements is adding wireless capabilities to conference rooms, giving workers access to important documents during meetings or conference calls. For those in the healthcare industry, WLANs enable doctors and nurses to enter or access key patient data at bedside or in an examination room.

WLANs can also play a central role in retailers' core operations. Many in the retail industry report using 802.11 networks with wireless handheld devices, to automate inventory and/or for transaction capture processes.

In addition to productivity, a common unexpected benefit from installing a wireless network, according to the companies surveyed, is improved employee satisfaction. While only 32% cited this benefit as a primary reason for adopting WLANs, 59% witnessed a lift in employee satisfaction owing to the new technology.

Security is a prime consideration for anyone contemplating WLAN adoption. While the WPA standard, individual software solutions and the forthcoming 802.11i standard have addressed many of the previous 802.11 security deficiencies, current users are still overwhelmingly apprehensive regarding their WLAN networks' vulnerability. In fact, most adopters cited insufficient security as a main drawback to owning WLAN technology.

These security concerns are not halting users' plans for expanding their WLAN networks, however. A majority of users are committed to broadening their WLAN investment in 2004. Additionally, most companies that are not increasing their 802.11 use this coming year did not cite security as a reason (it is more often just a case of no immediate need for expanded capacity).

To address potential security weaknesses, current users plan to fortify their existing WLAN networks with better security-management controls. In fact, 74% of companies expect to add improved security-management capabilities in 2004.

Survey respondents also indicated their planned spending levels for access points in 2004. The average 2004 access point budget for manufacturing (non-computer) companies is nearly $ 13,000, with retail firms budgeting more than $11,000 and healthcare organizations in excess of $9,000.

Wireless Router utilizes MIMO technology

2007-11-25T05:45:00.000-08:00

Wi-Fi[R] certified and backwards compatible with 802.11b/g, WRT54GX2 Wireless-G Broadband Router with SRX200 Router uses MIMO smart radio and antenna technology for optimal wireless communication speed and range. Overlaying signals of 2 Wireless G compatible radios enables product to utilize signal reflections that reduce dead spots in coverage area. For data protection and privacy, router can encode all wireless transmissions with WPA and has SPI firewall.

SRX200 Technology Delivers Increased Speed and Range at a Lower Price

IRVINE, Calif., Sept. 13 / -- Linksys(R), a Division of Cisco Systems, Inc., the recognized leading provider of voice, wireless and networking hardware for the consumer, Small Office/Home Office (SOHO) and small business customer, today announced a new addition to its award-winning SRX family of Wireless-G Broadband Routers. The WRT54GX2 Wireless-G Broadband Router with SRX200 uses MIMO (Multiple Input, Multiple Output) technology to bring users increased speed and range at a lower price.

MIMO Technology = Speed and Range Enhancement

MIMO technology, a key component in the upcoming Wireless-N (802.11n) standard, uses multiple radios and antennas on a wireless router or client adapter to provide improved performance in range and speed. By combining this smart radio and antenna technology with standards-based Wireless-G (802.11g), the WRT54GX2 has the potential to double* the range of wireless coverage compared to using Wireless-G alone. Overlaying the signals of two Wireless-G compatible radios enables the product to utilize signal reflections that confuse other technologies to increase range and reduce dead spots in the wireless coverage area. When used in conjunction with the WPC54GX Wireless-G Notebook Adapter or the WMP54GX Wireless-G PCI Adapter, the WRT54GX2 may yield up to six times* better performance as Wireless-G products. This performance enhancement is greatest at the outskirts of the coverage area.

Interoperability

Linksys SRX200 devices are Wi-Fi(R) certified and designed to be backward compatible with 802.11b (Wireless-B), 802.11g (Wireless-G) and other Linksys SRX products. Mixed wireless environments such as networks containing SRX, Wireless-B and Wireless-G products can operate each client at its own maximum data rate based on environmental conditions.* SRX products maintain their higher speed and range providing the throughput and quality of service to deliver applications such as VoIP and video streaming.

Security

To enhance both data protection and privacy, the SRX200 Router can encode all wireless transmissions with WPA (Wireless Protection Access.) It has a powerful SPI (Stateful Packet Inspection) firewall to enhance protection to all the wired and wireless PCs against intruders and most known Internet attacks while also supporting VPN pass through. Configuration can be done simply with the use of the web browser-based configuration utility.

"When we looked at the superb performance of our original SRX products, it became clear that we should offer a solution that brings the same benefits at a more affordable cost," said Tarun Loomba, Director of Product Management, Linksys. "The WRT54GX2 makes MIMO technology a viable option to users looking to spend a little less money on their network while still realizing performance greater than traditional Wireless-G products."

Pricing and Availability

The WRT54GX2 is available now through Linksys resellers including e-commerce, retail, direct response, and VAR partners at and estimated street price of $99.

Microsoft Enters Wireless Home-Networking Market

2007-11-15T04:57:00.000-08:00

Microsoft's next frontier might be your home network. The company's announced mission is to reassure potential buyers with its brand and to introduce ease of use (via simplified software) to a notoriously recalcitrant product area. The target customers are home users who already have broadband Internet connected to one PC and want to share the connection with additional computers. (The software doesn't support dial-up connections.)

We tested the Microsoft Broadband Networking Wireless Desktop Kit MN-610 ($220 street), which includes the Wireless Base Station (often called a residential gateway) and the Wireless USB Adapter to connect to a PC. We also tested the Microsoft Broadband Networking Wireless Notebook Adapter MN-520 ($80). Other products include a notebook kit, which bundles the Base Station and a PC Card adapter ($220), an unbundled Base Station ($150), and an unbundled USB adapter ($80).

Indeed, we found the information on the product packaging and in the paper and online documentation to be informative and easy to understand. In general, we found Microsoft's wireless products reasonably easy to install, though (like others in the field) not without flaws.

There are clear wins in Microsoft's industrial design of the Base Station and USB adapter. Both have relatively diminutive, attractive housings, and the Base Station comes with a small foot-style stand, so you can position it horizontally or vertically. The Base Station has four switched 10/100 Ethernet ports for connecting to network PCs, hubs, switches, bridges, and printers. If your cable or DSL modem has a USB connection only, you're out of luck, because the Base Station supports only the more-common RJ-45 Ethernet cable connection.

Other features in the Base Station include port forwarding, client and MAC filtering, and DMZ support. The built-in firewall does not include stateful packet inspection (SPI), a feature that is becoming more common in this class.

We applaud that Microsoft has chosen to ship its wireless products with WEP security turned on as the default (most others come with it turned off, and the majority of users never bother changing it). Similarly, you also must specify a network SSID (called a network name in Microsoft parlance) and a Base Station access password, both of which are usually set to default values in most products to aid installation. Many home users retain the factory default settings, leaving their networks wide open to wireless intruders.

We tested the wireless networking components on a variety of desktop and notebook PCs running Windows 98 SE, Me, 2000, and XP, connecting to the Internet via an SNET DSL PPPoE connection. After you install the Base Station, you can create a network settings floppy disk to use when installing adapters on additional computers to simplify entering SSID and security settings and keys.

We expected that the installation wizard would apply our already configured PPPoE settings to the Base Station automatically, but that didn't happen. (Microsoft's development team is looking into improving PPPoE capture in a future version.)

On one of our Windows 98 test systems, we were unable to enter the SSID of an Intel wireless gateway that was already present in infrastructure (base-station-to-PC) mode. We had to mark the network as peer-to-peer, enter our SSID, close the utility, reopen the utility, and redesignate the connection as infrastructure mode. In most cases, we had to restart the PCs two or three times during the install process to let all the software changes take effect, which grew tiresome.

Performance and range in our test home was similar to other 802.11b products. It took 2 minutes 46 seconds to transfer a 50MB file wirelessly between two PCs placed 40 feet apart; the average of competing products we've recently tested is 2 minutes 57 seconds.

The Microsoft broadband networking wireless products have a pleasing design and are fairly easy to install. But the products bring no new functionality to home and small-office networking. Microsoft's prices are somewhat higher than the going rates for competing vendors; whether buyers will buy a Microsoft product largely for the name remains to be seen.

Decision Point 1 Does a small business need Gigabit Ethernet?

Small companies can get big networking for little money these days. Wired, wireless, and Internet connection speeds come faster and cheaper than ever.

It makes good sense for you to pay a little extra to purchase Gigabit Ethernet rather than Fast Ethernet switches. Smaller companies will find Web-managed switches from companies such as Belkin, D-Link, Linksys, and Netgear for around $10 per port. Even small companies are moving around bigger and bigger files (video, graphics, and more), and Gigabit will really help also when you are performing over-the-network backups.

For wireless, 802.11g is the standard, but the time has come to consider draft 802.11n products, which offer five to ten times the performance and better coverage in a building. You'll find the routers and access points available for $100 to $150 from the same companies, and many new laptops have the option of including a draft 802.11n ExpressCard or PC Card. Make sure you run a secure wireless network by choosing WPA2 rather than the less-secure WEP option.

Using DSL or a cable modem typically provides enough bandwidth for most small businesses. Today's prices are impressively modest, but you might want to explore replacing the standard modem that comes with your service with product that supports VPNs for remote access. Ask your carrier about upgrade options.

Finally, although Wi-Fi can be found in many airports and cafés, mobile broadband provides connectivity almost anywhere you are. For $100 to $150 for the card and about $60 per month with preexisting voice service from AT&T or Verizon, you won't have to hunt around for a Wi-Fi hot spot.

Wireless Module simplifies broadband home networking

2007-11-09T01:03:00.000-08:00

Attaching directly to Series TJ700x Cable Modems, Model Wx-54G features modular architecture that enables operators to deploy unified cable modem and wireless home networking package. Module is based on 802.11g high-speed wireless networking standard, which supports up to 54 Mbps data rates. It can operate as wireless access point or as home gateway. Security features include 64-bit and 128-bit WEP encryption and shared key authentication.

Wireless Module Attaches Directly to TJ700x Series Cable Modems to Expand Service Levels

SANTA CLARA, Calif., Jan. 31 - Terayon Communication Systems, Inc. (NASDAQ:TERN), a leading provider of video processing and home access solutions, today launched a wireless home networking module that will enable cable television operators to simply and cost effectively deploy bundled high-speed data and wireless home networking packages.

Terayon's Wx-54G cable modem extension, an external add-on device for the Terayon TJ 700x series of DOCSIS(TM) (Data Over Cable Service Interface Specification) cable modems, attaches directly to the existing modem. The Wx-54G's modular architecture enables operators to deploy a unified cable modem and wireless home networking package on a 'pay as you grow' basis, without incurring networking equipment costs across the entire deployed modem base.

"As competition for customers increases, operators are looking for a combination of services that can enhance customer acquisition and retention," said Joseph Benigno, Terayon vice president and general manager, home access solutions. "By deploying the Wx-54G wireless home networking extension in conjunction with new or existing Terayon modems, operators can add a new application layer that increases the marketability and the 'stickiness' of the high-speed data service. Equally important, the unified solution provides a single point of customer support for cable operators and their customers that combinations of DSL and retail wireless home networking routers cannot match."

The Wx-54G module is based on the popular 802.11g high-speed wireless networking standard, which supports up to 54 Mbps data rates and allows subscribers to fully utilize the bandwidth performance of their cable broadband connection. Designed for exceptional flexibility, the Wx-54G can operate as a wireless access point, or as a full-fledged home gateway for users requiring routing capabilities and a firewall. The Wx-54G has numerous security features to ensure secure connectivity, including 64 bit and 128 bit WEP (Wireless Equivalent Privacy) encryption and Shared Key Authentication to prevent unauthorized users from accessing the wireless network.

The ability to integrate cable modems with add-on devices allows cable operators to initially deploy modems for high-speed Internet access, then to provide additional services and capabilities to subscribers as requested. This "pay as you grow" approach could be more cost-effective compared to broadly deploying home gateways that support multiple services in one device, but are primarily used for high-speed Internet access. Cable operators can also maximize their investments in cable modems, as the modems do not have to be replaced to deliver additional services.

About the Terayon TJ 700x Cable Modem Series

More than three million Terayon TJ 700x series cable modems have been deployed by cable operators worldwide to deliver high-speed Internet access, online gaming and other broadband services. The TJ 700x cable modem series currently includes the TJ 715x DOCSIS 2.0 certified modem, the Euro-DOCSIS 2.0 certified TJ 720x and the TJ 735x, which has been designed specifically for Japanese cable television operators.

Wireless LAN marches on: vendors pour in, prices come down, over-promise threat looms

2007-10-27T01:30:00.000-07:00

Wireless LAN (WLAN) silicon is clearly set to emerge from the downturn in much bettershape then it was just two years ago.

All the standard market maturity goals are being met. The number of chips to accomplish WLAN connectivity has been drastically reduced. The multipath distortion problem has been ameliorated. Laptop OEMs are embracing it to the tune of several million units this year. The semiconductor bill of materials is down about 75 percent. Venture capital and investments from IDMs are pouring in to the space.

Expect to hear a lot more about WLAN this fall, what with Cisco embracing 802.11 networks as "the next Internet" and Atheros out of the gate with its combination 802.11a and-b product. Intersil is sampling lots of new parts and Texas Instruments is going full force. Furthermore, upstart Magis Networks, with its proprietary 802.11a MAC, has so far netted $45 million from venture capitalists.

Intersil Corp., when it was still Harris Semiconductor, started engineering WLAN silicon in the early 1990s, long before the first 802.11 standard was ratified, but about the time the IEEE began debating radio transmit and receive functionality for intercomputer communication.

Jim Zyren, director of strategic marketing for wireless networking at Intersil, says the company has learned a lot since then and now feels very, very confident about the future of 802.11.

"The IEEE adopted 802.11b in 1999. And the market began to take off in 2000. In terms of unit volumes, 802.11b chipset shipments have been increasing every year, even through the downturn.
"Right now the 802.11 market is exceeding all of the forecasts that we've seen for the year," Zyren said. "Last year, overall, companies shipped somewhere around 7 [million] to 8 million radios worldwide. This year the forecast was for 13 [million] to 14 million. But we're here at almost the end of the year, and we can see it's going to exceed that. We're absolutely confident that the overall market will reach 20 million units in 2002," he said.

OEMs are clearly bringing in money on 802.11b. Gemma Paulo, senior analyst for enterprise and residential communications at In-Stat/MDR, has found that OEMs brought in nearly $1 billion in the first half of this year, selling 802.11b-equipped cards, adapters and the like. Cisco tops the list of vendors, but is followed by some lesser-known names--Linksys, Buffalo Technology, D-Link and Netgear round out the top five. (InStat/MDR is owned by Reed Business Information, the parent company of Electronic News).

Zyren said Intersil struck a critical deal during the summer with Cisco by which Intersil supplies most of the chipsets and Cisco provides its own proprietary MAC. Last week Cisco held a Webcast to detail its plans for WLANs and called the 802.11 nothing short of the next Internet.

The summer of 2002 saw a groundswell of popular support and increased consumer familiarity with Wi-Fi. In the media-saturated New York and San Francisco markets, there were daily reports of the sidewalk chalk marking denoting free Wi-Fi access and lots of efforts by residential broadband providers to clamp down on those who are piggybacking off their services. Not to be left out of this equation was the legion of laid-off tech workers wishing to get out of the house and continue job hunting in Wi-Fi-enabled coffee shops. These phenomena could well lead to strong demand during the holiday season for embedded 802.11 capability.

Intersil's Zyren said WLAN semiconductor suppliers have done a lot over the last two years with respect to silicon integration and taking advantage of smaller process geometries. That translates into lower power consumption--especially key for mobile applications and longer batter life -- and it also translates into less silicon overall, which lowers cost and enables smaller form factors. All of these things drive up volume as more OEMs can afford the capability, and more can accommodate it.

"Our first-generation chipset was five pieces of silicon," Zyren said. "One for the MAC, one for the baseband processor, a third for the baseband to intermediate frequency, a fourth for IF to radio frequency, and the fifth was the power amplifier.

"Now we have dramatically increased the performance in the baseband and integrated the baseband and the MAC since these are both digital functions. The other thing that enabled that is that process technology has improved. We were originally on a half-micron process, and now that's down to 0.18 micron," Zyren said. "Remember, the total silicon area and the power consumption are roughly proportional to the square of that feature size. So in going down to 0.18-micron, we got a major power consumption improvement.

"Another thing we've done is exploited things in the 802.11b standard that allowed the radio to go into sleep state. That greatly increases the efficiency of the wireless LAN device," Zyren said. "And we've eliminated the intermediate frequency entirely in the Prism3 chipset, so it's got direct down conversion technology." Here, WLAN leveraged work that cell phone chipset suppliers and OEMs were diligently engineering.
