Context aware multiple-input and multiple-output antenna systems and methods

摘要

A method, a system, and a server provide context aware multiple-input-multiple-output MIMO antenna systems and methods. Specifically, the systems and methods provide, in a multiple MIMO antenna or node system, techniques of antenna/beam selection, calibration, and periodic refresh, based on environmental and mission context. The systems and methods can define a context vector as built by cooperative use of the nodes on the backhaul to direct antennas for the best user experience as well as mechanisms using the context vector in a 3D employment to point the antennas in a cooperative basis therebetween. The systems and methods utilize sensors in the nodes to provide tailored context sensing versus motion sensing, in conjunction with BER (Bit Error Rate) measurements on test signals to position an antenna beam from a selection of several “independent” antenna subsystems operating within a single node, as well as, that of its optically connected neighbor.

1. A method, comprising:
receiving sensor measurements from a plurality of nodes tethered therebetween and each with a plurality of antennas and at least one sensor; developing a context vector for each of the plurality of nodes based on the sensor measurements, wherein the context vector for each node comprises conditions sensed by the node; determining a preferred orientation for each of the plurality of antennas based on the context vector for each of the plurality of nodes; performing calibration measurements for each of the plurality of antennas; and aligning one or more of the plurality of antennas at the plurality of nodes based on the calibration measurements and the preferred orientation for each of the plurality of antennas.
