What is generation of cellular network?

2.3. GSM uses a digital modulation format called 0.3GMSK (Gaussian minimum shift keying) . The 0.3 describes the bandwidth of the Gaussian filter with relation to the bit rate. GMSK is a special type of digital FM modulation.

1G, 2G, 3G, 4G and 5G are the five generations of mobile networks where G stands for Generation, and the number denotes the generation number . 5G is the latest generation, whereas 1G networks are now obsolete. The cellular technologies GSM, UMTS, LTE and NR enable 2G, 3G, 4G and 5G, respectively.

The coverage area of cellular networks are divided into cells, each cell having its own antenna for transmitting the signals. Each cell has its own frequencies. Data communication in cellular networks is served by its base station transmitter, receiver and its control unit.

A. The cellular communications networks are known by their numeric generation : 1G, 2G, 3G, 4G and 5G. We are currently fully deployed in 4G with 5G gaining ground.
