Abstract

A system for wireless communication comprises an architecture of routers connected to a network and having connected transceivers for wireless transmission and reception of data, and a plurality of hand-held communicators adapted for users to communicate with the network through the routers. The system is adapted to provide wireless Data Network Telephony (DNT), and the hand-held communicators execute Quality of Service (QoS) code adapted to prioritize DNT packet code over all non-DNT traffic, thereby preserving the real-time nature of the DNT code.

Claims

1. 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.

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

3. The system of claim 1 wherein one or more of the communicator units is equipped with noise cancellation microphone and speaker apparatus for creating a noise reduction zone in the region of a principle speech input microphone.
