Evolution of Mobile
The first radiotelephone service was introduced in the US at the end of
the 1940s, and was meant to connect mobile users in cars to the public
fixed network. In the 1960s, a new system launched by Bell Systems,
called Improved Mobile Telephone Service" (IMTS), brought many
improvements like direct dialing and higher bandwidth. The first analog
cellular systems were based on IMTS and developed in the late 1960s and
early 1970s. The systems were "cellular" because coverage areas were
split into smaller areas or "cells", each of which is served by a low
power transmitter and receiver.
