A Cell on Wheels, usually referred to as a “COW“, is a mobile cell site that consists of a cellular antenna tower and electronic radio equipment on a truck or trailer, designed to be part of a cellular network.
COWs are typically used during special events where a larger number of people will converge on one area, or in disaster areas if the base station has been damaged. The COW vehicle will consist of a cellular tower and all the support equipment needed to provide mobile wireless communications.
