Power efficient communications

摘要

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.

主权项

1. A wireless transmitting system, comprising:
an energy harvesting electrical power source, capable of producing an output power determined to be available; a transceiver configured to have 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; 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 determined available output power and to maximize consumption of the determined available output power by the transceiver; and a communication device, wherein a range between the transceiver and the communication device is estimated from the data reception rate and wherein an RSSI value is not needed to estimate the range.
