What is 1G

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 .

Enhancements that provide packet data capabilities over 2G networks . 2.5G improves the available data rates supported by the air interface, thereby permitting the introduction of new, data-oriented services and applications. General packet radio service (GPRS) is an example of a 2.5G technology. …

2G refers to the second generation of mobile networks based on GSM . The radio signals used by the 1G network were analog, while 2G networks were digital. 2G capabilities were achieved by allowing multiple users on a single channel via multiplexing. During 2G, cellular phones were used for data along with voice.

The “G” associated with cellular networks stands for generation . 5G is the fifth and newest generation of cellular network technology and it should expand the capacity for mobile networks, allowing more devices to use the network than ever before.
