What is Fleettalk?
Fleettalk began in the early 2000s when a group of land mobile radio dealers across the United States partnered to build a large, multi-state system using the newly developed NXDN (Next Generation Digital Network) protocol. Over time, the network expanded to support 12 dealers across 7 states.
What is Fleettalk by Rock?
Fleettalk by Rock is the portion of the system that covers South Carolina and parts of North Carolina. Known as System 219, it consists of more than 130 sites and nearly 1,000 channels, making it the largest NXDN Type-C trunking network in the world.
Where does it work?
The Fleettalk by Rock network provides mobile coverage to more than 99% of South Carolina, with strong portable coverage in many major metro areas including Columbia, Charleston, and Greenville, and extending into Charlotte, North Carolina.
What makes Fleettalk by Rock different?
Fleettalk by Rock is locally owned and operated. Our team includes people who have spent their careers in public safety and engineering. Together they bring more than 250 years of real-world experience, with over 200 of those years spent directly in public service. That kind of background is why the Fleettalk network performs the way it does when it matters most.
The performance speaks for itself. During Hurricane Helene in 2024, Fleettalk was recognized as the most reliable communications network in South Carolina. That level of reliability comes from the way the system is built. Fleettalk does not rely on traditional land-based interconnects. It operates on a statewide microwave network with both microwave and land-based redundant paths, and its decentralized architecture removes any single point of failure. There is no core, no need for site-trunking, and no scenario where one failed failure can take the system down.
Is Fleettalk by Rock P25?
No. Fleettalk uses NXDN, not P25, though the two have a lot in common. Both use the AMBE vocoder for high-quality audio, and both are open standards that allow multiple manufacturers to develop equipment.
The real difference is the platform. South Carolina’s statewide system, Palmetto 800, is an 800 MHz P25 network owned and operated by Motorola Solutions. Fleettalk by Rock, by comparison, is a statewide 450 MHz NXDN network. The lower frequency provides better in-building performance and wider coverage per site, which is a major reason Fleettalk by Rock delivers such consistent service across South Carolina.
