description A system for use with vehicle-based wireless multiple-input multiple-output (MIMO) communications equipment has several directional sub-arrays mounted on different faces of the vehicle. It is contemplated in typical operation that each sub-array will experience different channel conditions that can be evaluated with the help of pilot tones or training sequences transmitted from a remote communications device. Based on channel rank, or other appropriate metric, the system selects the sub-array with the best predicted performance for communication with the remote device. The system achieves better MIMO performance while contributing less interference to other nearby co-channel users and allows full use of the limited number of MIMO antenna elements supported by conventional 4G wireless standards.
