The problem with using radio signals so close to the GPS frequency (GPS is simply a very sensitive and sophisticated radio receiver) is that spillover can cause interference with the very faint radio signals received by GPS. Simply put, while we all want 5G, it can’t come at the expense of GPS .

In order to minimize and even avoid interference , the timing and synchronizations techniques used in the cellular network will need to evolve to support the new 5G requirements. The time of day messages and the timing pulse received from the GPS satellite constellation will also be used differently.
