What are the different generations of mobile communication?

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.

The speed increases and the technology used to achieve that speed also changes. For eg, 1G offers 2.4 kbps, 2G offers 64 Kbps and is based on GSM, 3G offers 144 kbps-2 mbps whereas 4G offers 100 Mbps – 1 Gbps and is based on LTE technology .

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 different types of mobile communication systems are a mobile two-way radio, public land radio, mobile telephone and amateur (HAM) radio .

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. See also wireless LAN, wireless glossary and Wi-Fi vs. cellular.

1G or (1-G) refers to the first generation of wireless telephone technology (mobile telecommunications). These are the analog telecommunication standards that were introduced in 1979 and the early to mid-1980s and continued until being replaced by 2G digital telecommunications.
