The network you trust has gone mission critical.

Introducing the CriticalLinc LTE network.

We've built redundant network data centers in Birmingham and Atlanta with backup power systems in each location.


Each cell site has an emergency generator or backup fuel cell to keep the power running for days during an outage.


We secured the CriticalLinc network in lockstep with Southern Company's multilayer, 24/7 IT security systems.

Mission Critical Push To Talk (MCPTT)

Don't sweat, CriticalLinc brings the mission critical PTT performance you trust. We've also added robust new Push To Talk features, so you can keep your team coordinated.

  • Priority Talk Group Scanning
  • Enterprise PTT Groups and PTT Contacts
