GSM GSM (Global System for Mobile communications) is a cellular phone system standard popular outside the USA. The speech signal is divided into blocks of 20 ms. These blocks are then passed to the speech codec, which has a rate of 13 kbps, in order to obtain blocks of 260 bits.
Note
The network administrator should balance the need for voice quality against the cost of bandwidth in the network when choosing CODECs.
