Abstract
A method and apparatus for wireless data transmission is provided between a base station and a backscatter-based transponder, in which the transponder generates a presence signal after initialization or at predetermined time intervals, independent of data transmitted by the base station. The presence signal is generated by phase modulation and backscattering of a carrier signal transmitted by the base station.
