Re: size not a major consideration in wireline phone sets [Telecom]

It was the regular mobile telephones that were so big and used so much electricity that they were trunk mounted. This was prior to cellular phones.

Commercial cellphones didn't get commercially going til about 1983 when the AMPS ("Advanced" Mobile Phone Service) was introduced commercially (in Chicago I believe.)

***** Moderator's Note *****

I think some of the early cellular phones were made to fit the same mountings and use the same antenna cables as their MTS and IMTS predecessors, so they may have been "bulky" in order to fit the old hardware. Since cellular came long after transistorized RF decks were common, cell phones never had to support the power demands of vacuum tubers: ergo, they never had to be the same size unless there were compatibility issues.

Any Motorola/GE/? techs care to chime in?
