Abstract

The American Telephone and Telegraph Company (AT&T) invented cellular telephony and launched the world’s first commercial mobile telephone service in St. Louis in 1946. However, it was launched under the tight regulation of the U.S. Federal Communications Commission, which controlled the frequencies allocated for the radio component of the system. Despite efforts by AT&T to persuade the FCC to extend spectrum allocation to permit the widespread deployment of the U.S. AMPS cellular standard, the FCC did not conclude its allocation of radio spectrum for radiotelephony until 1977.
