Walt, again they won't release significant details, but they (again) pointed me to their site re diff bw matched and correlation: <<Among GBT's most significant system advantages, is the ability to provide the means to achieve a connectionless packet switched network. In order to implement a packet switched architecture, the receiver must be able to rapidly detect and acquire the packet when it arrives; otherwise, because of the short packet duration, the receiver will miss the packet altogether. Achieving this rapid acquisition, in a wideband direct sequence system, precludes the use of the classic single correlator receiver, since such a receiver has an acquisition time which is much too long to be usable in this application. Although a correlation is acceptable for cellular circuit-switched telephony, it wastes capacity in a bursty environment such as Internet applications. However, if the correlator is replaced by a matched filter, rapid acquisition is an immediate outcome. GBT's proprietary matched filter based system design, will allow a wireless network to outperform a wireline network having the ability to handle individual datagrams without having to set up and maintain a continuous connection and thereby waste valuable capacity. In addition, because of surrounding interference, GBT also offers the best solution for highly congested environments because of its improved fade resistance. The GBT 2000 will support service information, wireless terminal equipment, wireless base station equipment, wireless switching office equipment, ancillary apparatus, auxiliary applications, inter-network and inter-system operations and interfaces. Narrowband-CDMA and GSM do not provide either wireline quality voice or the high data rate demands of third generation wireless standards. A fundamental weakness of CDMA systems is the near / far problem. In other words, CDMA systems require that all signals transmitted to the base station receiver, arrive at the same power level. This usually requires the use of complex algorithms to control the power of the users' near and far. If the users' power is not precisely controlled, the capacity and quality of the service will be significantly compromised.GBT's revolutionary adaptive power control overcomes the near / far problem by providing a fuzzy logic solution for each user. >> Q uses all correlation and would need a new ASIC to accommodate Nokia/ERICY branded WCDMA matched. I asked some specific questions. Let's see if he gets approval to answer them. He'll call back. gbtwireless.com
