Abstract:
An electronic device (50) includes an infrared transceiver (510) having adjustable infrared signal intensity capability. The electronic device (50) commences to establish communications with a secondary device (420 and/or 430) at a first power level, if the communication link is not established, the electronic device (50) increases the IR power level and tries again to establish communications. In an alternate embodiment, the electronic device (50) includes a power level table which keeps the power level which has been established for each secondary device (420, 430) using the method described above. The electronic device (50) before communicating with each of the secondary devices determines the proper power level to use depending on the secondary device (420, 430) it wants to communicate with. In still a further embodiment, instead of determining the power level to use at the start of the communications, an ongoing exchange of signal quality information is sent between the communicating devices in order to adjust the power level of the devices during the communication session.
