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 wireless transmitting system, comprising:

an electrical power source, capable of producing an available output power; and

a transceiver capable of a data transmission rate determined, at least in part, by the available output power and receiving data at a data reception rate determined, at least in part, by the available output power.

2. The system of claim 1, wherein the data reception rate is determined such that a reception range of the receiver is constant as the available output power varies.

3. The system of claim 1, wherein the data transmission rate is determined such that a transmission range of the transceiver is constant as the available output power varies.

4. The system of claim 1, wherein the system further comprises:

an electrical power monitoring circuit coupled to the transceiver and operable to monitor a power level of the available output power supplied to the transceiver by the electrical power source.

5. The system of claim 1, wherein the system further comprises:

a controller coupled to the transceiver that controls the transceiver to keep the power drawn by the transceiver from the electrical power source less than the available output power.

6. The system of claim 5, wherein the system further comprises:

a communication device, wherein a range between the transceiver and the communication device is estimated from the data reception rate.
