Abstract:
A wireless backscatter communication system, which may provide wireless control or input, is disclosed. The wireless communication system includes a source of an interrogating field and a reader. The wireless communication system also includes a device having a modulator for modulating the interrogating field with a coded signal and providing a backscatter modulated interrogating field which is detected by the reader. Shared reader circuitry also provides active wireless communication such as WiFi or Bluetooth. A non-limiting example application in a computer system and wireless keyboard is disclosed.

Claim (Index 10):
A wireless communication system adapted to wirelessly communicate with separate external devices respectively employing active RF communication and backscatter RF communication, comprising:\n a source of an RF interrogating field; at least one antenna adapted to receive RF signals from external devices including a backscatter modulated interrogating field signal and an active RF communication signal; and receive circuitry coupled to the at least one antenna for detecting information in the received RF signals including shared circuitry for detecting the backscattered and active signals, wherein the shared circuitry includes filtering circuitry functional to block signal components introduced by sharing of the circuitry.
