FieldComm 91 is LCWC's Field Communications Unit. The unit went into service April 2nd, 2003. The vehicle is a converted 35-foot motorhome that is used to provide on-scene communications and coordination at major emergencies and large public gatherings.

The interior of the vehicle is divided into two sections. The front section is a meeting area where command officers for the police, fire and ems agencies can meet to coordinate their response. The rear section of the vehicle is the communications area where LCWC's telecommunicators and supervisors handle most on-scene communications.

The communications section of Field Comm 91 contains three telecommunicator work areas. Each area is equipped with programmable radios capable of working on all public safety radio frequencies, a 4-line telephone set, and computer workstation. Other equipment in the communications section includes an aviation radio, a citizens band radio, a Uniden scanner, a radio interconnect unit, a combination printer/fax/copier/scanner and a 24" plotter for maps and posters.
