The issue of communications interoperability is nothing new. After 9/11, however, all Americans learned a painful truth that government agencies of all types had known for decades: Namely, that our separate communications systems — especially land mobile radio (LMR) systems — didn’t talk to each other. Since then, billions of dollars have flowed into so-called “radio interoperability” projects. Communications interoperability was supposed to be long past solved by now — except it isn’t. This Center for Digital Government issue brief takes a look at how new software is bridging the communication gap in government. This software enhances LMR systems and allows governments to leverage existing mobile devices and infrastructure so that all government agencies can communicate, whether in times of an emergency or in day-to-day operations.
