1. Cell Sites are the basic geographic unit of a wireless PCS or cellular system. A city or county is divided into smaller "cell" each of which is equipped with a low-powered radio transmitter/receiver. The cells can vary in size depending upon terrain, capacity demands, etc. By controlling the transmission power, the radio frequencies assigned to one cell can be limited to the boundaries of that cell. When a wireless PCS or cellular phone moves from one cell toward another, a computer at the switching office monitors the revenue generated by subscribers' calls outside of their system. In 1995, there were 22,663 cell sites and that number grew to 417,215 cell sites in 2020. In 2012 the average cell phone bill was $71 and the average annual data usage was 1468 megabytes. The number of subscribers increased from 33,786,000 in 1995 to 468,898,000 in 2020.
