Abstract
A wireless switch or sensor is provided that includes a radio frequency (RF) transponder including a narrowband receiver operable to generate power from a received narrowband RF signal and an ultra wideband (UWB) transmitter operable to transmit UWB pulses using the generated power.
Claims15
A wireless switch, comprising:
- a radio frequency (RF) transponder including a narrowband receiver operable to generate power from a received narrowband RF signal and an ultra wideband (UWB) transmitter operable to transmit UWB pulses using the generated power;
- and
- a switch, wherein the RF transponder couples to the switch to sense an on or off switch state for the switch, and wherein the UWB transmitter modulates the transmitted UWB pulses to transmit the sensed switch state.
A wireless sensor, comprising:
- a radio frequency (RE) transponder including a narrowband receiver operable to generate power from a received narrowband RF signal and an ultra wideband (UWB) transmitter operable to transmit UWB pulses using the generated power;
- and
- a sensor, wherein the RF transponder couples to the sensor to receive a sensor state for the sensor, and wherein the UWB transmitter modulates the transmitted UWB pulses to transmit the sensor state.
