Abstract

Unitary transceiving units employ a multiple carrier, time-division-multiple-access (TDMA), time-division-duplex (TDD protocol to conduct concurrent wireless voice and data communications wherein a first transceiving base station unit tethered to a network interface wirelessly communicates to a second, mobile transceiving unit. The mobile transceiving unit wirelessly transmits and receives packetized voice and data information that is separated and routed to respective voice or data networks. The unitary mobile transceiving unit thus functions as a concurrent voice phone and data communications terminal/computer.

Claims

1. A method, comprising for concurrent wireless voice and data communications between first and second transceiving units, the first transceiving unit tethered to a voice network and to a data network and the second transceiving unit being mobile comprising the steps of:

(a) providing plural frequency, time-division-multiple-access/time-division-duplex, channels;

(b) combining and transmitting both voice and data information on the plural channels; and

(C) receiving and separating the voice and data information.

2. The method as recited in claim 1 wherein the voice and data information are packetized into plural time slots within a time frame and share equal amounts of the time frame.

3. The method as recited in claim 2 wherein each of the plural time slots changes to a different one of the plural frequency channels after a predetermined number of consecutive frames.

4. The method as recited in claim 2 wherein a time slot containing data information further comprises a forward error correction code.

5. The method as recited in claim 2 wherein the number of plural frequency channels is greater than the number of plural time slots.

6. The method as recited in claim 2 wherein the number of plural frequency channels is less than the number of plural time slots.

7. The method as recited in claim 2 wherein the number of plural frequency channels is equal to the number of plural time slots.

8. The method as recited in claim 1 wherein step (a) adheres to the Digital Enhanced Cordless Telecommunications standard.

9. The method as recited in claim 1 wherein step (a) complies with Digital Enhanced Cordless Telecommunications standards.

10. The method as recited in claim 1 wherein the plural frequency channels operate between 2.4 GHz and 2.5 GHz.

11. A unitary transceiving unit comprising:

(a) a transceiver employing multiple frequency time-division-multiple-access time-division-duplex channels that supports concurrent wireless voice and data communications; and

(b) a baseband processor including a CODEC and at least one sub-processor to process audio generate tones provide echo canceling and to program slot and frame timing for the transceiver.

12. A unitary transceiving unit as recited in claim 11 wherein voice and data information are packetized into plural time slots within a time frame and share equal amounts of the time frame.

13. A unitary transceiving unit as recited in claim 11 wherein each of the plural time slots has a different one of the multiple frequency channels.

14. A unitary transceiving unit as recited in claim 11 wherein each of the plural time slots changes to a different one of the multiple frequency channels after a predetermined number of consecutive frames.

15. A unitary transceiving unit as recited in claim 11 wherein a time slot containing data information further comprises a forward error correction code.

16. A method comprising:

recieving voice information at a first transceiving unit over a first dedicated set of time slots associated with a first plurality of time frames of a wireless channel;

receiving data information from the first transceiving unit over a second dedicated set of time slots associated with the first plurality of time frames of the wireless channel; and

wherein each time slot of the first and second dedicated sets of time slots has a fixed time slot position for the plurality of time frames.

17. The method of claim 16, further comprising changing a carrier frequency of the wireless channel in a psuedo-random manner.

18. The method of claim 16, wherein the first dedicated set of time slots is a first number of time slots and the second set of dedicated time slots is a second number, the first number different from the second.

19. The method of claim 16, wherein the plurality of time frames comprises a sync bit associated with a first time slot of the first dedicated set of time slots and further associated with a first time slot of the second dedicated set of time slots.

20. The method of claim 19, wherein the first time slot of the first dedicated set of time slots and the first time slot of the second dedicated set of time slots are adjacent.
