Abstract: A fixed wireless access system is implemented using orthogonal time frequency space multiplexing (OTFS). Data transmissions to/from different devices share transmission resources using—delay Doppler multiplexing, time-frequency multiplexing, multiplexing at stream and/or layer level, and angular multiplexing. Time-frequency multiplexing is achieved by dividing the time-frequency plan into subgrids, with the subsampled time frequency grid being used to carry the OTFS data. Antenna implementations include a hemispherical antenna with multiple antenna elements arranged in an array to achieve multiplexing.

Abstract: An antenna system includes a lens portion that has a spherical surface, and an antenna feed structure coupled to a surface of the lens portion. The antenna feed structure includes one or more feed tiles supported by an electrical connectivity layer conforming to the spherical surface. The antenna system also includes one or more offset structures positioned between the one or more feed tiles and an outer surface of the antenna system.
