Abstract
A method of wirelessly communicating a screen image between a mobile device and a base station coupled to a display terminal includes receiving, at the mobile device, electromagnetic (“EM”) radiation emitted from a base station and incident upon an antenna of the mobile device. A screen image generated by the mobile device is encoded onto a backscatter channel of the EM radiation by modulating an impedance of the antenna. The screen image is transmitted from the mobile device to the base station for display on a display terminal coupled to the base station.
Claims21
A method of wirelessly streaming display data, the method comprising:
- receiving, at a mobile device, electromagnetic (“EM”) radiation emitted from a base station and incident upon an antenna of the mobile device;
- encoding a screen image generated by the mobile device onto a backscatter channel of the EM radiation by modulating an impedance of the antenna;
- and
- transmitting the screen image from the mobile device to the base station for display on a display terminal coupled to the base station.
At least one non-transitory machine-readable storage medium that provides instructions that, when executed by a mobile device, will cause the mobile device to perform operations comprising:
- modulating a radar cross-section of the mobile device between two or more states;
- encoding a screen image generated by the mobile device onto a backscatter channel of electromagnetic (“EM”) radiation incident upon the mobile device via the modulating;
- and
- transmitting the screen image from the mobile device over the backscatter channel of EM radiation for display on a display terminal remotely located from the mobile device.
A base station, comprising:
- backscatter transceiver circuitry coupled to output electromagnetic (“EM”) radiation and to receive a backscatter signal of the EM radiation;
- a display adapter;
- and
- control circuitry coupled to the backscatter transceiver circuitry and the display adapter, the control circuitry including logic, that, when executed by the control circuitry, will cause the base station to perform operations, comprising:
- output the EM radiation;
- establish a wireless display session with a mobile device;
- receive the backscatter signal of the EM radiation carrying a screen image signal encoded onto the backscatter signal from the mobile device;
- decode the screen image signal from the backscatter signal of the EM radiation;
- and
- output a screen image from the display adapter based upon the screen image signal for display on a display terminal.
