Abstract:
A data network telephony (DNT) system, comprising:a base station connected to a DNT-capable data network and to a wireless transceiver operating the transceiver by a two-way, narrow-band, multiple-channel, real-time duplex radio protocol, and processing DNT calls on the DNT-capable data network; a plurality of portable computer-enhanced communicator units, including microphone and speaker apparatus, each communicating with the base station by the two-way real-time radio protocol and processing DNT calls to and from the base station via the transceiver as DNT data packets; and a plurality of Digital Signal Processors (DSPs) operating in one or more of the communicator units for recognizing human speech; characterized in that the portable, computer-enhanced communicator units prioritize DNT data over other data when transmitting on the wireless network, such that DNT data always is processed before non-DNT data, and further characterized in that audio data for DNT calls is processed by the DSPs, allowing substantially only human speech to be prepared as DNT packets for transmission.
