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

In December, work will take place in the NW corner of level D and the NW corner of level B in the Plaza Garage, and on both levels of the DOT Garage. No major impacts to parking or traffic are expected. See maps of the work areas.
