What is the difference between 2G 2.5G and 3G?

2G mobile network is based on GSM(Global System for Mobile Communication). … Difference between 2G and 3G Cellular Network : 2G3GIt is less secure than 3G.Highly secure as 3G network permits validation measures.Video calls cannot be made.Video calls can be made.Difference between 2G and 3G Cellular Network – GeeksforGeeks www.geeksforgeeks.org › difference-between-2g-and-3g-cellular-network

2.75G EDGE It is an enhancement of GPRS and stands for Enhanced Data Rates for GSM Evolution. 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 .

GPRS is an up-gradation of GSM features over the basic features to obtain much higher data speeds and simple wireless access to packet data networks than standard GSM. It is the standard-bearer of the 2.5G technologies. … Difference between GSM and GPRS.
