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

1-7. -7. (cancelled)

8. A hand-held communication device, comprising:

microphone and speaker apparatus including converters for rendering audio data as audible speech, and for rendering audible speech as audio data;

a communication interface comprising circuitry for receiving and sending the audio data on a wireless network as Data Network Telephony (DNT) packets; and

circuitry including a Digital Signal Processor (DSP) recognizing human speech and processing audio data for DNT calls, the circuitry transmitting DNT data over the wireless network, enabling substantially human speech to be prepared as DNT packets for transmission.

9. The hand-held communication device of claim 8 wherein the device is implemented in the form of a cell phone.

10. The hand-held communication device of claim 8 further comprising a noise cancellation microphone and speaker apparatus for creating a noise reduction zone in the region of a principle speech input microphone.
