They were become more popular along with problems. Problems are limited capacity, to handle many cells, one way communication and so on. But some of them were compact by the use of new technologies such as FDMA CDMA AND TDMA. One of the most common digital networks that were developed in order to get rid of all sort of hurdles of analogue PCS. It can handle a lot of cells and flexibility during conversation.
