Digital
The current mobile technology that all networks in the UK use. Digital phones convert sounds into digital signals before transmission. At the receiving end, the information is reconverted. This allows better sound quality and increased security. Another advantage of digital mobile phones is that they allow several phones in the same area to use the same frequency simultaneously.
Digital networks include mobile systems GSM, D-AMPS, CDMA, TDMA and UMTS. They offer better coverage, more services and are more secure than the old analogue networks.
