Distributed Antenna System (DAS)

Distributed Antenna System (DAS)

Status: Construction

DES is working to install a Distributed Antenna System (DAS) in the Columbia, Plaza, Natural Resources Building and Transportation parking garages. The systems will improve public safety and security in the garage by improving radio and cellular communications. DAS also improves support for other systems that require cell phone connection within parking garages, such as EV chargers, automated key boxes and GPS mapping.

Latest updates

Throughout January, work continues in the DAS room near the Washington Street entrance of the Plaza Garage. No impacts to parking or traffic are expected.
