1.1 Frequency division multiple access (FDMA) FDMA is the most basic way of creating channels, by assigning users to nonoverlapping frequency bands, it was used in first and 2G cellular systems . In a system with N users and a total bandwidth W, each user can be assigned a bandwidth of W/N.

Read moreWhen was cellular network introduced?
History. The first commercial cellular network, the 1G generation, was launched in Japan by Nippon Telegraph and Telephone (NTT) in 1979 , initially in the metropolitan area of Tokyo. Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nationwide 1G network.
Read moreHow did cellular networks evolve?
The very first generation of commercial cellular network was introduced in the late 70’s with fully implemented standards being established throughout the 80’s . The radio signals used by 1G are analogue, meaning the voice of a call is modulated to a higher frequency rather than being encoded to digital signals.
Read moreWhat are cellular networks?
A Cellular network or Mobile network is a radio network distributed over land areas called cells , each served by at least one fixed-location transceiver, known as a cell site or base station.
