Wireless History Timeline - 1970s
FCC authorizes developmental cellular systems launch in Chicago and the Washington, D.C./Baltimore region.
The FCC revises it cellular allocation from 75 MHz to 40 MHz, restricts eligibility to wireline carriers, and adopts a one system per market policy because of its belief that technical complexity and expense would make competing systems in a market unviable. The FCC also decides to license developmental systems.
The FCC modifies its 1970 decision to allow non-wireline carriers (non-telephone companies) as well as wireline (telephone) carriers to access the 75 MHz allocated for common carrier radio cellular systems.
The FCC allocates 75 MHz for common carrier cellular systems out of the UHF spectrum
