GSM

udp

Global System for Mobile Communication (GSM) or 2G, is a mobile network in which the radio spectrum is divided into separate coverage areas (cells), each of which is served by a base station. Mobile devices (hardware) connect to the network via the radio channels available in the local service cell. GSM networks are divided into different frequencies. The speed is about 1 KB/s. This speed is too low to operate the emerging internet via devices. That’s why GPRS (2.5G) was designed. A data connection via GSM is no longer used, GPRS is the lowest connection standard.
