LOW COST PROXIMITY PAIRING MECHANISM IN WIRELESS PERSONAL AREA NETWORKS
First Claim
1. A wireless networking method, comprising the steps of:
- placing a master device and at least one peripheral device within proximity of each other;
transmitting a radio frequency request for proximity pairing from one of the peripheral device and the master device to the other of the peripheral device and master device;
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; and
after the proximity pairing is complete, transmitting operational signals from the master device to the peripheral device, the operational signals being transmitted with a second level of transmission power, the second level of transmission power being greater than the first level of transmission power.

Abstract
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.

15. A wireless networking method, comprising the steps of:
-
periodically transmitting synchronization beacons from a master device; placing the master device and a peripheral device within twenty feet of each other; receiving at the peripheral device at least one of the synchronization beacons from the master device; transmitting a radio frequency request for proximity pairing from the peripheral device to the master device; reducing a level of transmission power in the master device for proximity pairing; transmitting a radio frequency request for confirmation of the radio frequency request for proximity pairing, the request for confirmation being transmitted from the master device to the peripheral device; transmitting node identification information and security information from the master device to the peripheral device; and after the proximity pairing is complete, increasing the level of transmission power in the master device for future communication with the peripheral device. - View Dependent Claims (16, 17, 18, 19, 20)
