lCell phones may be new devices, but they originated in the 1920Õs. Radios were used since 1921. Features were put
into these radios in the 1940Õs, 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.
lThe 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.
