发明名称 Methods and apparatus for enhancing wireless data network telephony including a personal router in a client
摘要 A data network telephony (DNT) wireless communication system has a base station connected to a DNT-capable data network and to a plurality of wireless transceivers, each transceiver transmitting to a distinct area, the base station adapted to operate the transceivers by a two-way, narrow-band, multiple-channel, real-time duplex radio protocol, and a plurality of portable computer-enhanced client communicator units, including microphone and speaker apparatus, each assigned a unique address and adapted to communicate with the base station via the transceivers by the two-way real-time radio protocol and to process DNT calls. The wireless system operates as a carrier-sense multiple access system with collision detection (CSMA/CD).
