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.
