New DOCSIS Compliant Wireless Transceiver: A Low-Cost, Fast Deployment For Immediate Revenue Generation (2001)
By Ali A. Sayyah, AML Wireless Systems Inc.
This paper describes a low-cost wireless transceiver system that can be introduced as an alternative solution for difficult return path environments. The design challenges of such a transceiver system are discussed for both CATV and SMATV bands. The lack of a guard-band in the CableLabs DOCSIS protocol has been resolved by a novel frequency plan. Also, innovative techniques have been introduced for system automatic gain control and phase locking. Two-way digital testing of the new low-cost transceiver system has shown complete support of the DOCSIS protocol. Finally, testing has demonstrated full Federal Communications Commission (FCC) compliance for the wireless transceiver system.
