TACN – Tennessee Advanced Communications Network


The Tennessee Advanced Communications Network (TACN) is a statewide radio system that provides communication connectivity infrastructure for local, state, and federal first responders. With TACN, first responders, including law enforcement, fire, EMS, and healthcare providers, have reliable communications capabilities for daily operations and the ability to talk to each other to coordinate at the local, regional, and statewide level to respond in the event of an emergency or disaster.

TACN is made up of mobile and fixed radio transmission sites across the state so that from Tennessee’s urban to most rural areas, first responders will have consistent communication coverage. No matter where you are in Tennessee, even when other means of communication fail, TACN offers seamless communication for our partners. TACN has built-in redundancy to ensure the network will still offer statewide coverage in the event any location becomes inoperable after a natural or man-made disaster.

Because disasters know no boundaries, with TACN, local, state, and federal public safety agencies can respond as many but communicate as one. This interoperable communication is key to providing a swift and organized response that will save time, money, and citizens’ lives.

TACN, a division of the Tennessee Department of Safety and Homeland Security, is funded by the Governor and Tennessee General Assembly.
