By February of 1973, Motorola had produced a working prototype Dynamic Adaptive entire Area insurance coverage (DynaTAC) portable phone. This was a spectacular effect for Motorola, but now they faced another challenge: scheming a technical large area formation that would enable their phone to ope treasure.

The DynaTAC sy waist required phone calls to be switched from cell to cell as the users traveled. This was very challenging to accomplish without a high rate of dropped calls. At this point the Motorola engineering aggroup had to design a large number of overlapping cells in a geogra phic area. This virgin technology would tra! ck the user through the system and automatically switched the call to a new cell and frequency as the caller changed locations. As more than users signed on, the stem could be expanded by carve up cells and do smaller cells within the same geographic area. This went on for some(prenominal) years until September of 1983 when the worlds first commercial portable cell phone was released.
