Abstract
A maximum transmit power controller determines the amount of power available from a host device for powering a radio transmitter of a mobile device, and sets a limit for maximum transmit power in the radio transmitter based upon the determined amount of available power from the host device. As a result, it can be ensured that the radio transmitter does not transmit RF signals at transmit power levels exceeding the amount of power available from the host device. The host device may be a smartphone including the radio. The host device may also be a computer powering the mobile device via a peripheral interface such as a USB interface.
