phones may be new devices, but they originated in the 1920’s. Radios
were used since 1921. Features were put into these radios in the 1940’s,
and they were used by police. The concept of the cellular phone was developed
in 1947 which originated from the mobile car phone. The concept of the
cellular phone was produced by Bell Laboratories.
first actual cell phone was made in 1973 by Martin Cooper of Motorola
and other assisting inventors who used the idea of the car phone and applied
the technology necessary to make a portable cell phone possible. Cell
phones were first made available to the public in 1984. Back then, they
were very large, expensive instruments.
Federal Communications Commission made a regulation that limited radio-spectrum
frequencies. This is the reason only twenty-three simultaneous conversations
were possible in the same service area. In 1968 the FCC decided to increase
the frequencies to allow research for better connections. The FCC worked
together with AT&T and Bell Towers to establish broadcast towers.
The towers were small with low power and covered a “cell”
that was a few miles in radius, but actually covered a larger area. This
allowed calls to pass from tower to tower.
