Wireless vendors plan low-cost, high-speed metropolitan networks

Computerworld - Major chip and wireless equipment manufacturers today announced plans to back development of standards-based wireless metropolitan-area network (MAN) products that can provide 70Mbit/sec. of broadband data over a 30-mile range to customers -- and the equipment needed to access the service could be as cheap as today's wireless LAN access cards.
The companies, all members of the San Diego-based Worldwide Interoperability for Microwave Access Inc. (WiMAX) alliance, believe that by basing their products on the IEEE 802.16 wireless MAN standard, they can achieve the same economies of scale seen in WLAN products based on the IEEE 802.11b standard, according to WiMAX President Margaret Labrecque.
Labrecque, who is marketing manager of Intel's broadband wireless access initiative, said at a news conference today that alliance companies, which include Airspan Networks Inc., Alvarion Ltd., Aperto Networks, Ensemble Communications Inc., Fujitsu Microelectronics America Inc., Intel Corp., Nokia Corp., Proxim Corp. and Wi-LAN Inc., expect to start shipping products in the second half of 2004.
The 802.16 standard supports operation in a number of licensed and unlicensed frequency bands, including 1 to 2 GHz. Wi-Fi WLAN gear now in wide use operates in the 2.4- and 5-GHz bands. The 802.16 standard also supports operation in the 10-GHz band and from 12 to 66 GHz.
WiMAX envisions 802.16 products as a cost-effective alternative to today's current broadband options: telephone company T1 (1.54Mbit/sec.) circuits for corporate users and broadband cable service or Digital Subscriber Lines (DSL) for small businesses or residences, Labrecque said. Wireless base-station equipment would cost under $20,000, she said, with each base station capable of serving 60 enterprise customers with T1 circuits as well as a mix of residential and small business customers at lower DSL-type speeds of 256K or 384Kbit/sec.
Besides these uses, WiMAX also views 802.16-based systems as ideal to handle "backhaul" from 802.11b Wi-Fi hot spots -- such as those being installed nationwide by Intel-backed Cometa Networks Inc. (see story) to a high-speed network connection, Labrecque said. She said that an 802.11b card wouldn't work on an 802.16 network, although a router could serve as a bridge between the two wireless systems.
Dean Chang, director of product development at Aperto Networks, a manufacturer of broadband wireless equipment in Milpitas, Calif., said at the news conference that he expects to see a quick drop in the cost of customer premise equipment (CPE) next year, once the industry adopts the standard. Chang said CPE gear installation now costs $500 to $1,000. He expects that to drop to $300 once 802.16 equipment hits the
