It was 1993 when they build the first CDMA phone and tried to leave out alot of filters and RF components......only you were never able to BUY it.

They kept trying to build CW (continuos wave) type systems for a (CDMA) very linear system. analog is simple, kinda like building a CB radio. GSM is also very simple, just a simple digital modulation ontop of an analog waveform. Close to a CW system.
