Project 25 System of the Month:

Metropolitan Area Regional Radio System (MARRS), Kansas City

Mission Critical Magazine recently published an outstanding profile and history of the Kansas City P25 Regional Radio System.  The article was written by Jack Hart of Tusa Consulting Services, who has been the lead radio consultant for MARRS.

An excerpt from the introduction of the article is below. 

“A Kansas City area Project 25 (P25) network serves as a benchmark for multistate and regional public-safety radio communications.

By Jack Hart, Tusa Consulting Services

In less than eight years, MARRS has evolved from several incompatible, vendor-proprietary trunked systems and a conglomeration of conventional VHF, UHF and 800 MHz local systems into an integrated network that covers more than 4,000 square miles and serves a population of 1.2 million people. The entire system is designed to serve a portable on-hip user.

    MARRS consists of six large simulcast nodes plus multisites, for a total of 48 tower locations. The system supports radio traffic generated by more than 200 public-safety and public-service agencies across six counties — four in Missouri and two in Kansas — including 24 public-safety answering points (PSAPs). On an average day, system use is less than 50 percent, allowing sufficient available radio channel headroom for increased call volume because of a major incident or multiple incidents.”

The Project 25 Technology Interest Group is pleased to welcome our newest member Compliance Testing LLC.  Compliance Testing is a Full service Test Lab located in Mesa Arizona.  They offer Project 25 CAP testing services along with a wide array of other testing protocols including FCC, IC, CE, EMC, EMI, RF, SAR, and ETSI.  As a full service test lab with over 50 years experience, they can complete the entire FCC, IC, or CE compliance testing process for a client.

Most recently Compliance Testing has been promoting the concept of a single point test lab offering a multi-vendor P25 infrastructure test bed for P25 interoperability testing.  This concept would simplify and streamline P25 interoperability testing by eliminating the need and costs associated with visiting multiple P25 infrastructure vendors labs for testing. 

In addition, Compliance Testing published a recent P25 CAP AP report based on the CAP AP open meeting held at the APCO conference this year.  A link to this report is below.
