Abstract:
1. A technique for adjusting a transmit power level in a master transceiver comprising: a. transmitting first data by a master transceiver; b. detecting a transmission from a slave transceiver indicating whether the first data was accurately received by the slave transceiver; c. if the master transceiver detects that the first data was accurately received by the slave transceiver, then transmitting an acknowledge signal by the master transceiver to the slave transceiver; d. automatically lowering a transmit power level of the master transceiver; e. after automatically lowering the transmit power level, transmitting second data by the master transceiver; f. detecting any transmission from the slave transceiver indicating whether the second data was accurately received by the slave transceiver; g. if the master transceiver detects that the second data was accurately received by the slave transceiver, then transmitting an acknowledge signal by the master transceiver to the slave transceiver; h. raising the transmit power level of the master transceiver in the event that the master transceiver does not detect that the second data was accurately received by the slave transceiver and retransmitting the second data; and i. repeating steps f-h until the master transceiver detects that the second data was accurately received by the slave transceiver.
