GSM is a cellular network, which means that cell phones connect to it by searching for cells in the immediate vicinity. There are five different cell sizes in a GSM networkâ macro, micro, pico, femto, and umbrella cells.
GSM uses a variant of TDMA (time division multiple access) that divides the frequency bands into multiple channels. With GSM, our voice is transformed into digital data, which is given a channel and a time slot. On the other end, the receiver listens only to the assigned time slot, with the call pieced together.
