What is a cellular network?

cellular network, also known as mobile network, is a hardware architecture of mobile communication, which is divided into analog cellular network and digital cellular network. Because the signal coverage of each communication base station that constitutes the network coverage is hexagonal, the whole network is named like a honeycomb. Common cellular network types: GSM network (called pcs-19 in some countries), CDMA network, 3G network, FDMA, TDMA, PDC, TACS, AMPS, etc.
