At this point the Motorola engineering aggroup had to design a large number of overlapping cells in a geographic area . This virgin technology would track the us! er through the system and automatically switched the call to a new cell and oftenness as the caller changed locations. As more than users signed on, the stem could be expanded by carve up cells and make smaller cells within the same geographic area. This went on for some(prenominal) years until September of 1983 when the worlds first commercial-grade portable cell phone was released.
