South Metro Fire Rescue Authority (South Metro) in Colorado upgraded its mobile emergency communications network with Exalt Communications’ microwave radio systems. The organization deployed 4.9 GHz radio systems to increase bandwidth and reduce interference issues it faced with legacy Wi-Fi-based radio systems.

“We initially moved to a radio-based infrastructure about five years ago to improve capacity and eliminate recurring costs from leased T1 and ISDN lines, but we had a lot of challenges with interference from other users in the 5.3 and 5.8 GHz bands,” said Rob Krause, IT director at South Metro Fire Rescue Authority. “By using Exalt microwave radio systems in the 4.9 GHz public-safety frequency, we eliminated our interference problems while further improving capacity.”

To connect two towers, five fire stations and two headquarters buildings, the authority has so far deployed 20 radio systems in weatherproof enclosures, with six more systems yet to be deployed. The radio systems carry 55 megabits per second of Ethernet traffic support South Metro’s CAD system, IP telephony system, e-mail and other applications.

South Metro provides fire and emergency services over 176 square miles in Douglas and Arapahoe counties.
