1. A wireless device having a radio portion, the wireless device comprising:
- a beacon transmitter; and
a controller in signal communication with the radio portion and the beacon transmitter, wherein the controller instructs the beacon transmitter to transmit a beacon location signal that includes positional information of the wireless device in response to the radio portion of the wireless device that is in receipt of a beacon activation signal where generation of the beacon activation signal is initiated by at least one pseudolite or basestation.

Abstract
A wireless device capable of producing an emergency beacon signal is disclosed. The wireless device has a radio portion and may include a beacon transmitter and a controller in signal communication with the radio portion and beacon transmitter. The controller is capable of instructing the beacon transmitter to transmit a beacon location signal in response to the radio portion receiving a beacon activation signal. The wireless device may further include a satellite position system (“SPS”) receiver in signal communication with the controller.
