Abstract

A method, system, and device provide power-efficient communications within the context of available power. Transmission and receipt data rates are scalable in accordance with output power available from a power source. Data is transmitted at a data rate determined, at least in part, by the available output power.

Claims

1. A power-efficient communication device, comprising:

a transmitter capable of a data transmission rate determined, at least in part, by output power available to the transmitter from an electrical power source.

2. The device of claim 1, wherein the data transmission rate is determined such that a transmission range of the transmitter is constant as the available output power varies.

3. The device of claim 1, wherein the device is a transceiver further comprising:

a receiver operable to receive data at a data reception rate determined, at least in part, by the output power available from the electrical power source.

4. A method of power-efficient communications, comprising:

determining an available output power of an electrical power source; and

transmitting data at a data transmission rate determined, at least in part, by the available output power.
