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 .
Read moreWhat is difference between 2G 2.5G and 3G?
3G typically operates in separate frequencies than 2G and 2.5G uses , thus allowing mobile phones to switch from one to the other when capable. Summary: 2.5G implements packet switching along with the circuit switching in 2G. 2.5G has much faster data rates than 2G.
Read moreWhat is the architecture of 2G?
The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user’s mobile device and the base station and two core networks; one for circuit-switched voice and another for packet-switched data .
Read moreWhat is UMTS architecture?
UMTS system uses the same core network as the GPRS and uses entirely new radio interface . The new radio network in UMTS is called UTRAN (UMTS Terrestrial Radio Access Network) and is connected to the core network (CN) of GPRS via Iu interface.

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 . … This evolution journey was started in 1979 from 1G and it is still continuing to 5G .
Read moreWhat is speed of 2.5G network?
2.5G improves the available data rates supported by the air interface, thereby permitting the introduction of new, data-oriented services and applications. The increased data rates rise to a theoretical maximum of 384 Kbps , although in the field available data rates may often be as low as 20 Kbps.
Read moreWhat is difference between 2G 2.5G 2.75 g?
As in the case of 2.5G (GPRS), data is transmitted via the 2.75G (EDGE) network in small packets. The difference is that 2.75G delivers much faster data connectivity as the result of greater spectral efficiency . 2.75G EDGE can achieve download rates of up to 220 Kbps.
