Southern Linc announces LTE-to-LMR interoperability for public safety customers with L3Harris XL series radios

Customized Project 25 (P25) and LTE radios enable cross-network communications from a single device

ATLANTA, April 17, 2023 /PRNewswire/ -- Southern Linc, the wireless subsidiary of Southern Company (SO), has announced the availability of L3Harris Technologies radios, providing communications across LTE and P25 Land Mobile Radio (LMR) networks. The company will offer the XL Converge™ and XL Onboard™ series of portable and mobile units from L3Harris.

As the first LTE carrier to have an LTE-to-LMR solution actively deployed in the marketplace, Southern Linc provides private sector customers with their own radio systems the ability to use Mission-Critical Push-To-Talk (MCPTT) across the 122,000 square mile CriticalLinc™ LTE coverage area. "This solution has expanded MCPTT communications in areas where there formerly was none," said Southern Linc CEO Carmine Reppucci.

Through the partnership with L3Harris, which designed and built the first converged LMR with LTE on a P25 network, Southern Linc now offers a new and expanded level of interoperability with the XL Series. "The many months spent in development and testing of L3Harris devices for Southern Linc's highly reliable, highly secure CriticalLinc™ network have paid off with a robust and reliable MCPTT product offering," stated Southern Linc Engineering Director Alan McIntyre. "The collaboration with L3Harris to enable Southern Linc MCPTT service with their XL series of devices has been outstanding -- it truly provides our customers with the best of both the LTE and LMR worlds in a single device," he continued.

Southern Linc and L3Harris custom configure each XL Series radio to meet group and private MCPTT needs of each customer. The XL-185P and XL-200P are currently available, while the XL-200M mobile solution will be available starting next month.
