A public safety ERRCS DAS system is a specifically engineered radio communications system enabling first responders to utilize their portable radios inside structures for communications where DAQ (digital audio quality) is either insufficient or no useable RF signal penetrates from the local agencies’ prime communications site.

Upon completion of the appropriate engineering, the layout and components of the public safety ERRCS DAS are then configured. Dependent upon the local AHJ requirements, these can encompass; one or more exterior donor signal antennas, multiple interior distribution signal antennas, plenum rated RF transmission cable and or fiberoptic cable, passive devices to split, direct or combine signals, one or more BDAs, one or more BBUs, and possibly multiple fiberoptic remote transmission devices.

iBwave engineering via building design studies dictate the system configuration, primary and infrastructure components, RF and fiber optic cable layout and optimum placement of the interior signal distribution antennas. This ensures reliable public safety radio communications and guarantees a successful AHJ test and certification.

ERRCS DAS installation by Airwave's highly trained and experienced technicians is crucial to a successful public safety ERRCS DAS project. Their training includes but not limited to the following manufacturers: Bird, Comba, Westell, ADRF, Cel-Fi, Fiplex, Solid, Motorola Solutions and more. Your decision to utilize Airwave Communications to facilitate your ERRCS DAS project will stand as one of your most successful
