Patent ID: 7664162

Claim:
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 the host transceiver unit; 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 unit 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, said instructions further providing a marriage ID, said marriage ID being used by both said host transceiver unit and said human interface device to calculate said spread spectrum modulation pattern, such that said spread spectrum modulation pattern is a new pattern for both said host transceiver unit and said human interface device; wherein said instructions on said computer readable media further include routines for said host transceiver unit to generate a new marriage ID in a scanning state, said new marriage ID being used to communicate with only one human interface device in a connected state, said new marriage ID being determined after a series of handshaking steps between said host transceiver unit and said human interface device; wherein said spread spectrum modulation pattern hops a constant increment calculated from said marriage ID.
