Slow to start, the promise of Bluetooth may be kept after all

By BARNABY J. FEDER
NY Times News Service


The film Almost Famous is about the adventures of a reporter and a rock band, but the title works just as well to sum up the track record of the wireless communications technology known as Bluetooth.


Named for the 10th-century warrior king who united Denmark and Norway, Bluetooth is a design standard for making power-conserving electronic devices that transmit and receive modest amounts of data over short distances.


Developers of the standard, a group of communications giants led by companies including Ericsson of Sweden, Nokia of Finland and Intel, expected billions of Bluetooth products to be in homes and cars by now. The success has been more modest, partly because of delays in ironing out details and partly because of competition from other wireless standards.


Still, Bluetooth is making the leap into the automobile, enabling a driver to place hands-free calls from a personal cell phone -- even one tucked away in a purse -- using the speakers of the car’s sound system and the built-in microphones that serve voice-controlled navigation systems. Some models allow numbers stored in a mobile phone to be copied to the car’s system using the Bluetooth link.

Where Next for Sprint Hotspots?

Where Next for Sprint Hotspots?
By Adam Stone

Last summer, Sprint PCS said its users would have access to 2,100 hotspots nationwide within a year. In fact, the telecom giant has exceeded that goal, with roaming agreements that have brought into the Sprint fold some 3,000 hotspots. Where to next? We talked with Wes Dittmer, general manager of wireless LAN service for Sprint, about the company's ambitions and about the changing dynamic within the hotspot market.

Q: Your network now makes available some 3,000 hotspots. What's your next goal?

A: We have been saying that by the end of this year that number will be at least 10,000 hotspots, with some large North American percentage and some large international percentage. We are not deploying those ourselves. Those are hotspots that we have via roaming agreements with other providers, such as Wayport, AT&T Wireless, Truckstop.net, STSN, Concourse, Airpath and others.

War Flying
Bob wants to put WiFi in the Sky
By Robert X. Cringely

Why can't we use portable electronic devices in aircraft? Nobody seems to know for sure. There is the theory, of course, that listening to a CD player at the exact wrong moment will send your airliner crashing to Earth. That we're allowed to undertake such dangerous behavior above 10,000 feet is based on the idea that from that altitude, somebody is going to notice in time to stop the power dive. As a pilot for 34 years and a computer guy for nearly as long, my considered opinion is that this threat is exaggerated, and the point of this column is to lay out my plan to find whole new ways to use electronic devices aloft.

...

So here's my plan for really cheap aerial Internet service. I'm preparing a number of experiments using a Linksys WRT54GS 802.11g router mounted on the roof of my house in Charleston, SC. The router is running Sveasoft firmware that gives me direct control of transmitter power if needed. I'll be testing it with a variety of antennas, mainly omnidirectional but perhaps I'll try a sector antenna, too. The other end of the wireless connection will be a second WRT54GS mounted in my funky homebuilt airplane. Operating the pair of routers as an Ethernet-to-Ethernet bridge will give me much higher performance than I could ever expect from just using a WiFi card in my notebook computer. And I'll be testing a variety of antennas on the belly of my funky airplane, too.

...

What I expect will happen is I'll be able to fly near Charleston and connect to my home network at 1-2 megabits-per-second. I'll learn which antennas work best together. I may even place or receive a few VoIP phone calls using phone software running on my notebook computer. It will be interesting to see how far I can get from Charleston before losing service. It will be VERY interesting to see whether I can connect to WiFi base stations other than my own. I'm guessing such war flying will be possible, though I can't guess how reliable.

...

Now -- strictly because I am twisted this way -- let's take this experiment a step further. Sveasoft supports mesh networking, though with a practical limit of three hops. Aerial WiFi links of 10+ KM ought to be possible and maybe a LOT longer. The hardware cost of a WRT54GS and antenna are on the order of $100. There are, at the moment I am writing this, more than 1,000 small aircraft flying on IFR flight plans in the U.S. So for not very much money you could have a 1,000-node aerial mesh that could serve not only airborne but also terrestrial users. Triple the money, and you could put in each plane a Locustworld mesh with two radios for each node and truly robust mesh networking.

Electronic News - Wi-Fi Weds Bluetooth

Wi-Fi Weds Bluetooth
By Suzanne Deffree -- Electronic News, 7/15/2004

It was inevitable. As connectivity has continued its evolution of putting more functions in a single box, the pairing of more than one popular wireless technology into a single device was just a matter of time.

That's why companies are now putting Wi-Fi and Bluetooth together into handhelds such as smartphones and PDAs. But while this marriage may seem like a dream come true for consumers, as demonstrated by the popularity of the combo in the consumer market, it's proven to be a challenge for OEMs and chipmakers faced with the task of getting these star-crossed lovers to work together.

That's because both technologies work on the 2.4GHz frequency. The industry sought to address this challenge with the Bluetooth 1.2 specification, which defines a mechanism called adaptive frequency hopping that allows Bluetooth to "hop" around the wireless LAN in use.

Next-Gen Wireless Equipment Vendors Are in a Dogfight for Buyer Mindshare, New Study Finds
Monday July 12, 11:01 am ET
Latest Heavy Reading market perception survey shows no clear leaders among major suppliers of 3G wireless infrastructure gear


NEW YORK, July 12 /PRNewswire/ -- Makers of infrastructure equipment for third-generation (3G) wireless networks are in a pitched battle to win recognition as market leaders from prospective customers, according to a major new report from Heavy Reading (http://www.heavyreading.com), the market research division of Light Reading Inc.
Heavy Reading's 2004 Next-Generation Wireless Infrastructure Market Perception Study presents the full results of an exclusive, invitation-only survey of wireless network operators worldwide. The survey measures wireless operator perceptions of equipment vendors in five critical categories -- name recognition, price leadership, product performance, product quality and reliability, and service and support.

The study covers ten key next-gen wireless market segments, including base stations, controllers, microcells and picocells, and other equipment deployed in 3G wireless networks. It covers 34 different 3G vendors, including Cisco Systems (Nasdaq: CSCO - News), Ericsson (Nasdaq: ERICY - News), Motorola (NYSE: MOT - News), and Nortel Networks (NYSE/Toronto: NT).

"An oligarchy of incumbent vendors dominates mindshare in the 3G wireless infrastructure market, but no single supplier in the group has a clear advantage," notes Heavy Reading analyst Tim Kridel, who authored the 61-page report. Kridel notes that seven vendors had average name recognition scores of 70 percent or higher from the 169 respondents participating in the survey.

Other key report findings include:

Vendors that offer a full suite of products are in better position to capture wireless service provider customers. Respondents identified interoperability as a major problem in the 3G market, indicating that despite the wireless industry's move toward open standards, interoperability concerns present an opportunity for companies that offer a full product suite.

Among the startups in the 3G wireless infrastructure sector, IPWireless has done the best job of establishing itself in the eyes of the market. Airvana, AirWalk Communications, and InterWave Communications also achieved respectable name recognition scores from respondents.

Buyers of next-gen wireless infrastructure have a cautiously optimistic outlook for 3G. When asked to describe their overall perception of the 3G wireless market, nearly 25 percent of the respondents who answered this survey question called wireless a "growing" market.

Heavy Reading's 2004 Next-Generation Wireless Infrastructure Market Perception Study is published in PDF format and priced at $2,950. The price includes full access to a searchable database of survey results.

Meru Makes WLAN Deployment and Optimization a One-Button Process

SUNNYVALE, Calif.--(BUSINESS WIRE)--July 12, 2004--
New System Director v2.0 with E(z)RF(TM) Eliminates Site Surveys, Optimizes Performance, and Simplifies Ongoing WLAN Management with the Touch of a Button





Meru Networks today introduced System Director v2.0 featuring E(z)RF(TM), the first self-optimizing WLAN system with one-touch installation. Available immediately to new customers and as a free upgrade for existing Meru customers, System Director 2.0 sets a new standard for wireless LAN deployment and management simplicity.

"With E(z)RF(TM), Meru has eliminated the deployment and ongoing WLAN management complexity and associated costs that we've seen in other systems," said Don Carlos, director of information services and technology at United Teachers Los Angeles. "This network is as close to plug-and-play as any enterprise-class Wi-Fi system we've seen."

To deploy a Meru WLAN, users simply place Meru Access Points (APs) in areas to be covered and then click a button on the E(z)RF user interface to instantly optimize the entire network based on the unique characteristics and application demands of the deployment environment. Whenever there are significant changes in the environment, another click on the E(z)RF button takes care of it.

"Radio Frequency Spectrum Management (RFSM) is a critical need that's not achieved significant visibility with either vendors or users to date," said Craig J. Mathias, a principal with the wireless advisory firm Farpoint Group (Ashland, MA). "And it's a perpetual challenge. Tools like Meru's E(z)RF have the potential to dramatically lower costs, improve performance, and increase user satisfaction across essentially every wireless-LAN venue and application."

Meru Air Traffic Control Technology Creates Self-Optimizing WLAN

Traditional WLAN system vendors have created software wrappers that support manual optimization of off-the-shelf access point (APs). These products allow users to adjust AP power levels and prioritize traffic as it enters the wired LAN via the WLAN switch or controller. However, these tools must be continually re-used as the network changes, driving up ongoing management costs. In addition, traditional WLAN architectures do not solve the inherent problems of over-the-air service quality and contending traffic among neighboring APs. As a result, a typical WLAN's performance degrades if there are too many access points too close to each other because of co-channel interference.

In contrast, Meru's architecture is based on its patent-pending Air Traffic Control (ATC) technology, which includes the industry's only WLAN control plane that dynamically coordinates APs at a packet level, mitigates co-channel interference, provides over-the-air QoS for the entire WLAN coverage area, and optimizes overall performance.

"Wireless LAN performance isn't just about speeds and feeds. Equipment that is easier to deploy and operate reduces total cost of ownership, provides more predictable Wi-Fi service throughout an organization, and ultimately improves overall user satisfaction," said Kamal Anand, vice president of marketing at Meru Networks. "Meru has proven that we provide five times the throughput of traditional wireless LANs and that we lead the industry in service reliability, even for time sensitive applications like VoIP. With our new E(z)RF capabilities, the Meru wireless LAN system now leads the industry in yet another element of wireless LAN performance - ease of deployment and optimization."

Meru's Wireless LAN System includes the Meru Access Point, a standards-compliant 802.11 access point that simultaneously acts as an access point and RF monitor; the Meru Controller, a centralized gateway by which all security, QoS and management policies can be configured and enforced across the entire wireless LAN, and the Meru System Director, an extensible, embedded software suite.

About Meru Networks, Inc.

Meru Networks is the wireless LAN performance leader, and makes the only enterprise WLAN infrastructure that delivers the service reliability, scalability, security, and ease of use that are essential for pervasive wireless deployments.

Wireless Chip Maker Fuels Call for Multiduty Access Points

Wireless Chip Maker Fuels Call for Multiduty Access Points
By Carmen Nobel
July 12, 2004



WLAN (wireless LAN) hardware manufacturers are gearing up to take advantage of new silicon that promises to increase range and decrease the price of enterprise access points.

Chip maker Engim Inc. this week will introduce a high-capacity wireless LAN chip set, which officials said will be used by several major access point manufacturers in products due in the next six months.

The EN-3001 Intelligent Wideband Wireless LAN chip set is what the Acton, Mass., company dubs an "all services access point" processor, designed to support multiple functions simultaneously.

The EN-3001 increases the range and throughput capacity of a typical WLAN threefold, using a technique called wide-band spectral processing, which allows an access point to support multiple radio channels. Engim's new version bests its predecessor, the EN-3000, by including embedded Ethernet media access controls, which allows licensees to create thin access points for WLAN switching infrastructures.
