Licensed Points To Point Microwave Service
Licensed Microwave service has been used since the 1960s to transmit very large amounts of data. The AT&T Long Lines coast to coast backbone in the USA was largely carried over a chain of microwave towers. These systems have been largely using 3700-4200 MHz and 5000-6200 MHz. The 5 GHz band was even known as the "common carrier" band. This service typically was prohibitively expensive to be used for Local Loop, and was used for backbone networks. In the 80s and 90s it flourished under the growth of cell towers. This growth spurred research in this area, and as the cost continues to decline, it is being used as an alternative to T-1, T-3, and fiber connectivity.
