Abstract

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).

Claims

1. A data network telephony (DNT) system, comprising:

a base station connected to a DNT-capable data network and to a wireless transceiver and operating the transceiver by a wireless protocol;

a communicator unit, including microphone and speaker apparatus, adapted to communicate with the base station by the wireless protocol and to process DNT calls; and

at least one Digital Signal Processor (DSP) for recognizing human speech in each of the communicator units;

wherein the base station processes DNT calls on the DNT-capable data network and broadcasts and receives the DNT calls to and from the communicator unit via the transceiver as DNT data packets, and wherein the communicator unit creates data packets for transmission only in response to the DSP recognizing human speech by monitoring voice inputs for non-descriptive audio, which may be ignored as non-speech.

2. The telephony system of claim 1 wherein the DNT-capable data network is a local area network (LAN).

3. The telephony system of claim 1 wherein the voice recognition function of the DSPs may be programmed or trained to recognize different languages.
