1. A data network telephony (DNT) system, comprising:
- a base station connected to a DNT-capable data network and to a wireless transceiver and adapted to operate the transceiver by a two-way, narrow-band, multiple-channel, real-time duplex radio protocol, and to process DNT calls on the DNT-capable data network and to broadcast and receive the DNT calls to and from the plurality of communicator units via the transceiver as DNT data packets; and
a plurality of portable computer-enhanced communicator units, including microphone and speaker apparatus, each adapted to communicate with the base station by the two-way real-time radio protocol and to process DNT calls;
wherein the portable, computer-enhanced communicator units are adapted to prioritize DNT data over other data when transmitting on the wireless network, such that DNT data always is processed before non-DNT data.

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.

5. In a system providing wireless communication between a portable communication unit and a base station over a dedicated channel, wherein the portable device is adapted for Data Network Telephony (DNT), a method for enhancing quality of DNT calls, comprising steps of:
-
(a) monitoring all outgoing wireless traffic at the portable communication unit;
(b) recognizing DNT data as opposed to non-DNT data; and
(c) transmitting DNT data always with preference over non-DNT data. - View Dependent Claims (6, 7)
