Push-to-Talk over Cellular (PoC)


Push to Talk over Cellular (PoC) uses 4G, 5G, LTE, and Wi Fi networks to provide secure, instant, wide-area radio-style communication. You do not have to buy, operate, or maintain traditional radio repeaters or base stations to reach drivers and field staff across town or across the country.

With Hytera PoC solutions from Fleet Radio, teams get one-button push-to-talk for individuals and groups, plus fast call setup that feels like a two-way radio, not a phone call. Voice is carried over commercial data networks, so you can talk between job sites, branches, and mobile crews wherever there is good cellular or Wi Fi coverage.

Modern PoC devices add more than voice. Many models support GPS location, text and multimedia messages, emergency alerts, and photo or video sharing to a dispatcher’s screen, helping supervisors see where people are and what is happening in real time. Cloud dispatch tools can manage talk groups, view live maps, and review call history from a browser-based console.

PoC works well on its own or as a partner to a DMR radio system. Hytera platforms can bridge broadband and narrowband, so office staff, phone users, PoC radios, and traditional DMR handhelds can all be part of the same talk groups when needed. Fleet Radio can help you determine when a PoC is the right fit, select the right Hytera devices, and set up a service plan that matches your routes, job sites, and budget.
