Before cell phones …

In 1978, Bell Labs launched a trial of first commercial cellular network in Chicago using AMPS [1]. … The first handheld mobile phone to become commercially available to the US market was the Motorola DynaTAC 8000X, which received approval in 1983. Mobile phones began to proliferate through the 1980s with the introduction of “cellular” phones based on cellular networks with multiple base stations located relatively close to each other, and protocols for the automated “handover” between two cells when a phone moved from one cell to the other. At this time analog transmission was in use in all systems. Mobile phones were somewhat larger than current ones, and at first, all were designed for permanent installation in vehicles (hence the term car phone). Soon, some of these bulky units were converted for use as “transportable” phones the size of a briefcase. Motorola introduced the first truly portable, handheld phone. These systems (NMT, AMPS, TACS, RTMI, C-Netz, and Radiocom 2000) later became known as first generation (1G) mobile phones.
