Lucent ASIC doubles voice capacity in BTSs Posted : 26 Dec 2002 eetasia.com Lucent Technologies has developed an ASIC that can deliver a two-fold increase of voice capacity in 3G cdma2000 basestations (BTSs) by utilizing an intelligent antenna feature. Designed for integration into Lucent's Flexent Modular Cell 4.0 cdma2000 basestation, the IC is claimed by the company to be capable of boosting the data capacity by more than 100 percent to accommodate the growing demand for mobile high-speed data services, as well as increasing the data throughput. Without per-user intelligent antenna processing, a BTS' antennas produce a wide-angle radio signal beam that transmits to all users in a given area. However, with per-user intelligent antenna processing, the BTS sends a separate, dedicated, narrower beam to each active user, which adaptively follows them as they move through the basestation's coverage area. Transmitting simultaneous, dedicated beams to each active user makes more efficient use of spectrum and reduces interference, resulting in capacity gains. Lucent's intelligent antenna processing techniques are also applied to the "reverse link," or the signal a basestation receives from a mobile device when a voice or data call is active. ----- This would seem to mean that such enhanced technology could be implemented w/o any handset changes. Also note that not only would this double capacity, but it would increase data throughput.
