Abstract:
1. A system for wireless transfer of data, said system comprising: a host transceiver unit configured to be connected with a host via a bus, and configured to wirelessly exchange data with a human interface device; a human interface device configured to wirelessly exchange data with a host transceiver; and computer readable media having instructions thereon, said instructions comprising routines for synchronizing said host transceiver unit and said human interface device for wirelessly exchanging data between said host transceiver and said human interface device at a spread spectrum modulation pattern which is determined by said host transceiver unit after said host transceiver unit and said human interface device have acknowledged each other's presence; wherein said host transceiver unit is configured to broadcast at one of a plurality of host spread spectrum modulation patterns, each of which is a function of a host communication state; said human interface device is configured to broadcast at one of a plurality of device spread spectrum modulation patterns, each of which is a function of a device communication state; and wherein said host transceiver unit and said human interface device broadcast at a same spread spectrum modulation pattern after said host receiver and said human interface device have acknowledged each other's presence.
