Delta Airlines is currently planning to upgrade this TRS, and several others that they operate at other airports around the nation, to fully compliant Project 25 trunking technology. This project should be completed within the next 2.5 years, with major hub airports given priority consideration. No word on what vendor will receive the contract install the new digital trunking systems. Moreover, nearby public safety first responders, will be given a chance to use this system as a backup, should their primary radio system fail for any reason at Memphis International Airport.
