Abstract:
Automatic establishment of a connection between a human interface device and a host transceiver unit. A marriage ID is exchanged in a synchronization step. The marriage ID being used by both the host transceiver and the human interface device to calculate a spread spectrum modulation pattern. In one embodiment the spread spectrum modulation is a frequency hopping spread spectrum modulation.
