Blog Editor’s Note: GPS signals already contribute to efficient spectrum use. Precise GPS timing enables multiplexing, simultaneous use of the same frequency by multiple users.
This application allows 5G transmitters to determine if their physical surroundings shield them enough from other transmitters that they can use the same frequency without interfering with each other. – Pretty clever.
Folks just keep on finding ways our essential GPS signals can be used, making them even more essential!
So we really need to ensure they aren’t interfered with accidentally or on purpose – including legally authorized emissions from out of band.
Full disclosure, iPosi has been a corporate member of RNT Foundation since 2014.
The Defense Spectrum Office (DSO) of the U.S. Department of Defense (DOD) has contracted iPosi Inc. and Virginia Tech Applied Research Corporation (VT-ARC) to develop a GPS/GNSS system to measure radio frequency path loss that substantially increases shared spectrum without interference.
The contract addresses the need for increased shared spectrum between DOD and wireless providers who require expanded access because of skyrocketing demand for broadband 5G spectrum.
