Abstract

An improved multiple-input multiple-output (MIMO) solution is disclosed for customer premises equipment (CPE) in which a set of wireless interfaces (e.g., cellular and WiFi), each with a plurality of antenna ports for MIMO operation, couple to an antenna switch fabric, which is then coupled to a set of antennas. In some examples, the antennas are distributed for maximum isolation and separation in order to improve MIMO channel separation, for example in an approximately spherical arrangement. The antenna switch fabric is instructed to select the optimal antennas based on signal parameter measurements, in order to improve overall performance. Selection of uplink (transmit) versus downlink (receive) antenna sets may be independent and based on different signal parameter measurements (e.g., for frequency division duplexing, FDD).
