Radio Deployment Wave Overview
The deployment waves are the end-user agency groupings and the timeframe in which they will be exchanging their current radios for new radios. The PSERN Project assigns agencies to waves based on their primary geographic location of daily operations and the talkgroups (radio channels) they utilize on the emergency radio system. Wave start and end dates shift due to several factors, but the latest estimated wave dates can be found here:
