Southern Linc Rolls Out Motorola PTT for Mission-Critical LTE Network
Thursday, November 03, 2016 | Comments

Southern Company subsidiary Southern Linc chose Motorola Solutions' broadband push-to-talk (PTT) solution for its mission-critical Long Term Evolution (LTE) network.

PTT is a critical communications service for Southern Co., and the WAVE 7000 solution will combine sub-second PTT call performance with various broadband applications. The technology will provide quick communications between coworkers, as well as interoperability with work groups and other organizations using the network, a statement said.

"PTT is a vital communications tool for our utilities and for public safety," said Tami Barron, Southern Linc President and CEO. "The value of PTT to Southern Company was demonstrated recently in the storm recovery efforts following Hurricane Matthew. PTT was an essential tool used to coordinate response activities with Georgia Power, Georgia Department of Transportation (GDOT), Georgia Emergency Management Agency (GEMA) and other first responders."

PTT users will be able to establish and participate in enterprise-level group calls, and they can create individual ad-hoc groups for personal group calls. Users can also use one-to-one private communications with individuals when needed. Broadcast group functionality — the ability to make announcements to teams of users and limit responses — is available as well.

To ease the transition from Southern Linc's iDEN network to the new LTE network, the PTT service will offer interoperability, enabling users on the LTE network to communicate with those on the iDEN network.

Southern Linc is constructing an LTE Advanced (LTE-A) network to meet the increasing mission-critical data needs of its largest customer, Southern Co.'s electric utilities. The highly reliable network will have the capacity to serve the most crucial data needs of area businesses and local government as well. The network will offer network encryption over the air (OTA), and the PTT service will be encrypted from user to user. In addition, the company is further strengthening emergency backup power capabilities with hydrogen fuel cell technology at key locations and is adding main power and core data center redundancy to increase the reliability of the new network.

Southern Linc plans to begin migrating existing PTT users to the new LTE PTT solution in 2018.
