What is the history of cellular?
The mobile communications industry started in 1921 when two-way radios were installed in the cars of the Detroit Police Department. This equipment was bulky and awkward to use, but it allowed the department’s scout cars to keep in touch with headquarters.

No direct dialing capabilities were available. Therefore calls to and from mobile subscribers were routed through special operators. There were long waiting lists to become a subscriber and once service was obtained, users often experienced long delays because only a small number of channels (radio frequencies) were available. Mobile units used a single channel, push-to-talk system that allowed only one person to speak at a time.
