Claim:
1. A wireless transmitting system, comprising: an energy harvesting electrical power source, capable of producing an available output power for an indefinite period of time and having a defined peak power characteristic; a power efficient transmitter, configured in operation to enable a ratio of peak-to-average power consumption of the available output power of the energy harvesting power source to be minimized and to enable energy consumption of the available output power of the energy harvesting power source to be maximized per unit time and capable of a data transmission rate, wherein the data transmission rate is determined, at least in part, by the available output power; and a power efficient receiver configured in operation to enable the ratio of peak-to-average power consumption of the available output power of the energy harvesting power source to be minimized and to enable energy consumption of the available output power of the energy harvesting power source to be maximized per unit time and operable to receive data at a data reception rate determined, at least in part, by the output power available to the receiver from the electrical power source; wherein a range between the transmitter and the receiver is determined from the data transmission rate of the transmitter, and wherein a received signal strength indication (RSSI) value is not needed to estimate the range.
