Device-to-device communications in 5G—known as sidelink—promise to provide new flexibility and functionality, but its potential range is expected to pale in comparison to the land-mobile-radio (LMR) direct-mode offerings used by public-safety responders today, according to National Institute of Standards and Technology (NIST) research.

Chunmei Liu, a researcher in the Wireless Networks Division of the Communications Technology Laboratory (CTL) at NIST, said that 5G New Radio (NR) sidelink is projected to support device-to-device communications at a maximum distance of 981.8 meters—slightly less than 5/8ths of a mile—in an “idealistic” scenario outdoors with line of sight, based on simulation research (graph pictured above). More realistic scenarios in the research indicate a device-to-device range of 644.9 meters (705.3 yards) for a pedestrian user and 582.0 meters (636.5 yards) for a user inside a vehicle.
