If you do not choose the right radio, your emergency communications will not work.
A bold statement, but 9/11 showed that inter-agency radio operation is a challenging technical problem. Major public safety emergencies involve first-responders from many different government and private organizations. Personnel are borrowed from neighboring cities or states; thus, there is a need for communications systems that interoperate.
The FCC has moved aggressively to allocate spectrum and assist the industry in developing the necessary standards. In support of this, the agency has defined several topics related to reliable backhaul radio. These topics include operability, interoperability, security, efficiency, reliability, resiliency, redundancy, and scalability. A key component of this is the P25 digital trunk standard, which was created to facilitate radio interoperation, as well as other goals.
To insure interoperability, the FCC has set strict standards for P25 systems. Among these standards are requirements for digital traffic transport at very low latency and very low jitter.
Backhaul for P25 systems can be accomplished using a variety of different frequency bands and radio configurations, some more applicable than others depending upon the deployment scenario. Exalt offers an extensive range of microwave backhaul radios that meet the strict latency and jitter requirements for P25 while providing network designers with a variety of configuration and frequency options that allow for a custom-fit backhaul solution to the challenges
