Low cost proximity pairing mechanism in wireless personal area networks

摘要

A wireless networking method includes placing a master device and at least one peripheral device within proximity of each other. A radio frequency request for proximity pairing is transmitted from the peripheral device to the master device. Radio frequency proximity pairing signals implementing the proximity pairing are transmitted from the master device to the peripheral device. The proximity pairing signals are transmitted with a first level of transmission power. After the proximity pairing is complete, operational signals are transmitted from the master device to the peripheral device. The operational signals are transmitted with a second level of transmission power greater than the first level of transmission power.

1. A wireless networking method, comprising the steps of:
placing a master device and at least one peripheral device within proximity of each other; implementing a standard pairing process between the master device and the at least one peripheral device; transmitting a radio frequency request for proximity pairing from one of the at least one peripheral device and the master device to the other of the at least one peripheral device and master device after the standard pairing process; transmitting radio frequency proximity pairing signals implementing the proximity pairing from the master device to the peripheral device, the proximity pairing signals being transmitted with a first level of transmission power, the first level of transmission power being less than a second level of transmission power used during the standard pairing process; identifying a signal strength of the proximity pairing signals; and disconnecting a connection established in the standard pairing process based on the signal strength of the proximity pairing signals being less than a predetermined threshold signal strength.
