Abstract

Systems, techniques, and devices for performing variable power transmission for a battery-powered device are disclosed. In certain embodiments, the techniques include determining a proximity of the transmitter to a first display device. An output transmission power of the transmitter is determined based on the proximity. Analyte information from an analyte sensor coupled to the transmitter is transmitted to the first display device at the output transmission power.
