Abstract

A range equalization transceiver system (100) for increasing efficiency of a continuous duty communications link includes a first transceiver (105) for transmitting data traffic over a broadband traffic channel and a second transceiver (107) for determining routing information using a discovery channel based on link quality. A controller (103) is used for interpreting routing information from the second transceiver (107) where the controller (103) selects a transmitting scheme based on data traffic conditions on both the broadband traffic channel and link quality channel for sending data over a wireless network.

Claims

1. A two-way radio transceiver system comprising:

a first transceiver for transmitting data traffic over a broadband traffic channel;

a second transceiver for determining routing information using a route discovery channel;

a controller for interpreting routing information from the second transceiver; and

wherein the controller selects a transmitting scheme based on the routing information for sending at least one data packet, wherein the transmitting scheme comprises;

transmitting, by the second radio transceiver, the at least one data packet along a route to a destination using both the broadband traffic channel and the route discovery channel when the broadband traffic channel is congested;

sharing transmitting, by the first radio transceiver and second radio transceiver, of the at least one data packet using both the broadband traffic channel and the route discovery channel when the route discovery channel is underutilized; and

transmitting, by both the first radio transceiver and second radio transceiver, a duplicate of the at least one data packet along a route to a destination using the broadband traffic channel and the route discovery channel when the at least one data packet has a high quality of service (QoS) requirement.

2. A two-way radio transceiver system as in claim 1, wherein the transmitting scheme includes both traffic modulation and coding of data packets.

3. A two-way radio transceiver system as in claim 1, wherein the second transceiver operates at a low power level for decreasing the amount of current drain.

4. A two-way radio transceiver system as in claim 1, wherein the second transceiver operates at a high duty cycle for continually receiving routing information.

5. A two-way radio transceiver system as in claim 1, wherein the first transceiver and second transceiver are used in an inversely proportional manner depending on utilization of the route discovery channel.

6. A two-way radio transceiver system as in claim 1, wherein

the first radio transceiver operates at a first power level;

the second radio transceiver operates at a second power level below that of the first power level; and

the controller selects the transmitting scheme based on quality of service (QoS) information within the routing information.

7. A two-way radio transceiver system as in claim 6, wherein the second radio transceiver operates at a high duty cycle in order to conserve current drain on the two-way radio transceiver system.

8. A two-way radio transceiver system as in claim 6, wherein the controller performs route discovery based upon the QoS information.

9. A two-way radio transceiver system as in claim 6, wherein the transmitting scheme includes both modulation type and coding scheme.

10. A two-way radio transceiver system as in claim 6, wherein the first transceiver and second transceiver are used in an inversely proportional manner depending on utilization of the route discovery channel.

11. A two-way radio transceiver system as in claim 6, wherein the first transceiver operates using an IEEE 802.11 standard.

12. A method for determining range equalization in a two-way radio transceiver system comprising the steps of:

establishing a broadband traffic channel for transmitting data using a first radio transceiver;
