Broadband moves wireless ahead

Telephony; Chicago; Jul 3, 2000; Nancy Gohring;

Broadband wireless becomes a legitimate access option as vendors display solutions for MMDS, LMDS and unlicensed spectrum


Supercomm traditionally hasn't had a strong wireless presence. Perhaps it is testament to the momentum behind broadband wireless that at this year's show, wireless meant broadband wireless-and lots of it. Although broadband wireless vendors largely didn't uncover earth-shattering developments, their booths were some of the busiest.

The unlicensed bands continue to get attention as vendors develop new products for the space. Adaptive Broadband demonstrated its products operating at four frequencies at the show, including its unlicensed-national information infrastructure (U-NII) solution.

Dave Frank, president and chief operating officer of Fuzion Wireless Communications, discussed Fuzion's use of Adaptive Broadband's U-NII product. Fuzion has a network operating in Florida and plans to roll out services nationwide."I have the ability to walk in and rapidly deploy with competitive pricing and undercut the competition," Frank said.

Adaptive Broadband's product is unique, he said, because it allows Fuzion to remotely provision increased bandwidth on the fly for customers that might have a one-time need for more bandwidth.

Adaptive Broadband also introduced a prototype of its new local multipoint distribution service (LMDS) product and demonstrated its multichannel multipoint distribution service (MMDS) offering at the show.

Nokia made an entrance into the broadband fixed wireless arena with a new mesh broadband fixed wireless system that operates in the 2.4 GHz frequency The architecture does not rely on central base stations.

"Every subscriber is part of the infrastructure," said Ari Leppa, general manager for Nokia Networks. The equipment at each user's location passes data to the next user until the data reaches the Nokia Airhead, which connects to the Internet. Nokia also introduced point-topoint radios that can carry 125 Mb/s. Netro will supply the radios for the point-to-point offering on an OEM basis.

The U.S. market got a new competitor in the unlicensed arena with Nera Telecommunications, a Norwegian-based provider of fixed wireless products that made its U.S. debut at Supercomm. Nera's Velocity-2000 wireless local loop offering operates in the 2.4 GHz ISM band and delivers 115 kb/s data plus two voice lines per user. Nera believes competitive local exchange carriers (CLECs) may be interested in using its products in regions where landline facilities may be deteriorating or in underserved markets.

The MMDS explosion

In addition to products operating in the unlicensed frequencies, several vendors, including Breezecom, introduced products aimed at MMDS licensees. Breezecom recognizes that there may be very different users of MMDS offerings-ranging from residential customers to large businesses-and has developed products for both. The residential of fering is designed for easy self-installation.

"It can be installed via priority mail," said Tom Walusek, director of sales for OEM/ MMDS for Breezecom. For businesses that might have a lot more users in one location, Breezecom has a higher-density design, which is stackable and allows for hundreds of users.

Wi-LAN introduced a new family of products, based on its patented wideband orthogoval frequency division multiplexing technology, starting with MMDS and multipoint communications system offerings. By the first quarter of 2001, Wi-LAN aims to introduce products for most bands below 6 GHz with a price point of less than $500.

With the competition and flat-rate pricing schemes common in the U.S., a $500 price point will allow the infdustry to take off, said Hatim Zaghloul, chairman and CEO of WiLAN. Until then, it may be difficult to build a business. "Everyone offering [broadband wireless] in the U.S. today is losing money;' Zaghloul said.

ADC Telecommunications is moving ahead with its MMDS product, getting a vote of confidence from the Mexican government, which commissioned ADC and Telinor Telivision to conduct field trials of two-way MMDS services. The government will use results of the trial to create a service definition for MMDS spectrum in Mexico.

Nokia introduced a fixed wireless system that operates in the unlicensed frequencies at Supercomm. Ari Leppa, general manager for Nokia Networks, describes the self configuring mesh architecture of the new products.

"MMDS as a one-way product was a good business but not as attractive as twoway," said Peter Jew, director of marketing for broadband wireless access at ADC.

ADC has an OEM agreement with Vyyo, which is supplying the radios for ADC's MMDS product.

Despite the increasing variety of MMDS products on the market, one of the few commercial MMDS operators isn't using those products. In Phoenix where Sprint is commercially offering Internet access using MMDS, the operator uses equipment from Hybrid and California Amplifier. Sprint reGently raised its second tower in the area and now reaches about 85% of the market.

"We don't have to compete head to head often with DSL and cable," said Evan Conway, senior director for Sprint's broadband wireless group. That's because those technologies have left large pockets of users without access.

The single stick architecture that Sprint and most MMDS operators are using today may satisfy some of the FCC's hopes for closing the digital divide. A single stick architecture covers a high percentage of residents within a radius. "It reaches about 35 miles and doesn't discriminate-it gets into rural areas, too," Conway said.

Mobile Internet gets support
Although mobile wireless exhibitors were scarce at Supercomm, some major players made announcements and John Zeglis, chairman and CEO of the AT&T Wireless Group gave the opening speech on the first day of the show.
Zeglis emphasized the importance of partnering with applications developers as the way to foster growth of the wireless Internet. "We'll run the world's greatest invitational," he said. AT&T Wireless plans to make it attractive for developers to create applications that will run over its network.
Zeglis showed off some ideas for nifty applications with which AT&T Wireless has been toying. One hand-held device he used as an example could be used by school kids. Users could point the device at a historical site, and AT&T Wireless' location technology could identify the site and then deliver information about the site to the device.
Zeglis also donned a pair of space-aye ski goggles that would allow users to see maps of ski areas on the inside lens. Users also could record a video of their vision or send a realtime video of their experience to someone else.
Heavy-hitting vendors displayed their plans for allowing operators to achieve the capabilities that would allow such applications. Lucent Technologies continued to put the pieces together for a complete platform to enable wireless operators to roll out mobile Internet capabilities. At Supercomm, Lucent introduced the Flexent Wireless Router, designed by Bell Labs specifically for wireless networks. The router adds to Lucent's vision of migrating operators that use any air interface into next generation networks.
"Our challenge was how to leverage a common [base station transceiver] and use R&D efficiently," said Cynthia Christy, vice president of Lucent.
In addition to the common software-- defined radio base station platform that Lucent previously introduced, the vendor also offers an IP server based on Sun Microsystems technology and a wireless data gateway, which lets operators add mobile Internet applications. Together, Lucent believes these solutions can bring operators to next generation networks.
Motorola showed off its GSM enhanced data rates for GSM evolution (EDGE) solution at Supercomm. U.S, operators are aggressively moving toward EDGE networks and so will European operators, despite the rapid progress of universal mobile telecommunications system UMTS) license awards processes there, said Mike Malone, vice president and general manager of EDGE systems for Motorola. Even the operators that own UMTS licenses will deploy EDGE outside of the big cities to continue to earn revenue from the spectrum they already own, he said. Motorola is developing handsets that will roam between EDGE and UMTS networks.
John Zeglis, chairman and CEO ofAT&T Wireless Group, waxed about futuristic wireless data concepts at Supercomm. AT&T Wireless plans on aggressively encouraging wireless data application development.

Even though Sprint hasn't yet marketed the service in Phoenix, it's been surprised by the uptake. Sprint currently serves 3000 to 4000 customers, half of which are new customers, Conway said.

Like most operators that prefer the multivendor approach, Sprint may begin to look at other vendors in future markets. The operator will soon be targeting Colorado Springs, Colo. Digital Microwave Corp. also announced at the show that it will provide an MMDS system for an unnamed operator in Colorado Springs. DMC said the network will support as many as 5000 users.

LMDS moves ahead

DMC also touted its point-to-point solutions at Supercomm, announcing a contract with KDD/Winstar in Japan.

The need for high-capacity, point-to-point radios will likely continue to grow, said Stuart Little, director of broadband product marketing for DMC. The advent of cellular systems led to a boom in point-to-point radios, which were used for backhaul. Third generation systems may lead to an increase in a similar type of application. In addition, point-to-point radios can meet the demand for high-speed access, which continues to grow despite the decrease in the growth of fiber, Little said.

"Point to multipoint can't provide the capacity in demand," he said. DMC believes it's in a good position to meet that demand, especially because it has been producing high volumes for years.

Other vendors are taking steps to meet that increasing demand for capacity. Giganet Limited has expanded its 115 Mb/s product to handle higher data rates. At Supercomm, Giganet introduced upgrades to its FibeAir product that will deliver 311 and 622 Mbls data rates using the same amount of spectrum as its 115 Mb/s offering. In the U.S., operators could offer as much as 622 Mb/s using the typical 50 MHz wide channel.

Giganet also touted its ability to interface with various transport protocols, including IP, ATM and Sonet. The solutions are available in a range of frequencies.

Ensemble Communications showcased its LMDS offerings at the show and discussed a close partnership it is building with Lucent Technologies. Lucent and Ensemble are suppliers to Adelphia Communications, an LMDS license holder.

At Adelphia's suggestion, Lucent and Ensemble began working together to offer Adelphia a turnkey solution. The relationship between Lucent and Ensemble could extend to other customers that need integration services.

"We can leverage Lucent's talent in design, build and support," said David Twyver, president and CEO of Ensemble.

Ensemble's point-to-multipoint system helps Lucent reach operators that may be moving into their second stage of build. "In the U.S., service providers paid a lot for spectrum so they tried to focus on larger companies with point to point," said Bob Schleicher, general manager of Lucent's broadband wireless access unit. That, he said, is the first stage. The second stage involves introducing point-to-multipoint networks to reach more customers. Adelphia skipped the first build and is moving straight for the point to multipoint strategy, Schleicher said.

Wavtrace showcased its broadband faced access time division duplexing/TDMA solution at the show. The solution is suited for unpredictable data traffic because it allows the amount of data traveling in one direction to instantly change based on how much data is being carried. It also can instantly change the upstream and downstream links.

Some of the large broadband fixed service providers in the U.S. have expressed concern over the ability of small vendors to meet increasing demands for product. Wavtrace believes that it has prepared for the possibility of large orders. "We've made our manufacturing scalable," said Thomas van Overbeek, president and CEO of Wavtrace.

In its own category, AirFiber showcased its wireless optical solution at Supercomm. AirFiber's mesh architecture delivers 620 Mb/s to users. The company introduced its solution in April. Nortel Networks plans to use AirFiber on an OEM basis, and KDI in Japan has successfully tested the equipment.
