Base Station (BS) - The node that logically connects fixed and mobile subscriber stations to operator networks. The BS governs access to the operator networks and maintains communications with client devices. A BS consists of the infrastructure elements necessary to enable wireless communications, i.e., antennas, transceivers, and other electromagnetic wave transmitting equipment. BSs are typically fixed nodes, but in a tactical environment, they may also be considered mobile.
