Adaptive Broadband Promotes Standardization for Wireless Broadband Access Technology
SUNNYVALE, Calif., Apr 3, 2000 (BUSINESS WIRE) --
Initiative Intended to Drive Equipment Costs Down, While Allowing Ubiquitous Support for Current and Emerging Broadband Technologies
Adaptive Broadband(tm) Corporation (NASDAQ:ADAP) announced today that it is engaged in an active initiative to allow for open standards of its AB-Access(tm) technology. According to the company, the move is a result of increasing customer feedback that illustrates the need for Time Division Duplexing (TDD) technology rather than legacy Frequency Division Duplexing (FDD) for the emerging broadband wireless technologies.
"Today we have the ability to use TDD or FDD for point-to-multipoint broadband wireless access systems," said Dr. Demosthenes Kostas, director of standards for Adaptive Broadband. "A problem we are seeing is the proliferation of adaptations of emerging wireline technologies, such as DOCSIS-based FDD systems, being used for point-to-multipoint broadband wireless access systems. Global channel plans require efficient usage of bandwidth. TDD permits simple and efficient dynamic allocation of the radio uplink and downlink bandwidth, and TDD does not require paired frequencies. These efficiency and flexibility attributes cannot be met by FDD broadband wireless access systems."
Initiative Strives for Interoperability
Adaptive Broadband is proactively working with various international standards bodies, including the IEEE 802.16 on Broadband Wireless Access, ETSI Project-Broadband Radio Access Networks, and ETSI TM04 Work Group on Fixed Radio Systems, to establish fixed broadband wireless access standards that consider the proven AB-Access physical and media access control layer. This AB-Access combination yields a low-cost, point-to-multipoint broadband wireless access solution for service providers to offer video, voice, data, and Internet over the same high-speed wireless link. The intent of the Adaptive Broadband standards initiative is to further drive down equipment costs and allow service providers to select interoperable equipment from multiple vendors that support a wide range of services.
"In the IEEE 802.16 we are currently focusing our efforts to actively support two newly formed groups. One is developing a point-to-multipoint broadband wireless access system air interface standard for the licensed bands between 2 and 11GHz. The other group is studying the issues relating to developing a similar standard for the license-exempt bands between 5 and 6 GHz, that will enable public metropolitan area network access to connection oriented and/or connectionless data, video, and voice services," continued Dr. Kostas.
Broadband Applications Require TDD Architecture and Flexibility
The wireless broadband market is estimated to be $100 billion over the next ten years. "We have been deploying operational equipment which is providing commercial service, while competitive peers are on holding patterns offering `field trial' technology," said Dr. Daniel L. Scharre, executive vice president of Adaptive Broadband. "We have been successful with the AB-Access platform because our technology is not based on legacy technology that only offers fixed, asymmetric links. Other broadband equipment providers have not received the message yet that current and future broadband applications demand the dynamic architecture and flexibility of TDD. We intend to accelerate the growth of broadband applications through our open interface initiative and encourage vendors of alternative technologies to do likewise. This not only ensures that service providers will have choices, but that these choices will be provided cost effectively through multiple vendors offering interoperable products."
