Cell on Wheels. 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 used to provide expanded cellular network coverage and/or

capacity at special events such as major sporting events, while an Emergency COW is used in disaster areas where

cellular coverage either was never present (e.g. in a wilderness area where firefighters have set up a command center

during a major forest fire) or was knocked out by the disaster (such as a hurricane or large wildfire). COWs may also be

known as COLTs (Cell On Light Trailer) by some companies.
