摘要： A method and apparatus for wirelessly communicating data that receives electromagnetic (“EM”) radiation incident upon an antenna of a mobile device from a base station is described. The antenna is an element of the mobile device that serves an additional purpose than just as a reflective antenna for backscatter communications. A radar cross-section of the antenna is modulated between two or more states using a backscatter tag coupled to the antenna. Data is encoded onto a backscatter channel of the EM radiation via the modulating. The data is transmitted to the base station over the backscatter channel.

摘要： Backscatter communication includes receiving electromagnetic energy from a base station and encoding first data and second data. The first data is encoded at a first frequency by adjusting a radar cross-section of a device to modulate the electromagnetic energy reflected back to the base station. The second data is encoded at a second frequency by limiting the adjusting of the plurality of radar cross-sections to either a first subset or a second subset of the plurality of radar cross-sections for a length of time. The second frequency is lower than the first frequency.

摘要： A system includes one or more optical emitters, a transceiver, and a body mountable device. The optical emitters emit light and are configured to be used in luminaires. The transceiver is coupled to receive input data from a data network and coupled to selectively modulate the optical emitters to transmit the optical data. Selectively modulating the optical emitters is in response to the input data. The body mountable device includes a photodetector coupled to receive the optical data and processing circuitry configured to initiate an action in response to receiving the optical data from the photodetector.

摘要： A method of wirelessly communicating a screen image between a mobile device and a base station coupled to a display terminal includes establishing a wireless display session between the mobile device and the base station. Electromagnetic (“EM”) radiation emitted from the base station is incident upon an antenna of the mobile device. The screen image is transmitted to the base station for display on the display terminal by modulating a radar cross-section of the mobile device between two or more states to encode the screen image on a backscatter channel of the EM radiation.

摘要： A backscatter receiving module and a method of backscatter communication is described. A front-end module receives the backscatter signal from an antenna and generates high-speed and low-speed data. A high-speed decoding module outputs first data in response to the high-speed data having high-speed symbols that were encoded at a first frequency. The high-speed symbols include a first subset of symbols and a second subset of symbols. A low-speed decoding module outputs second data in response to receiving the low-speed data that was encoded into the backscatter signal at a second frequency. The low-speed decoding module generates a first state of the second data when the high-speed symbols of the high-speed data are in the first subset for a length of time. The low-speed module generates a second state of the second data when the high-speed symbols of the high-speed data are in the second subset for the length of time.
