What is the difference between 2G, 3G and 4G?

It is sometimes difficult to differentiate between these three expressions that are very much used by Telecommunications operators. These icons appear on the mobile next to the network bars and reflect the type of mobile network you are connected to. Each mobile network generation (2G, 3G, 4G) corresponds to a new technology (GSM, GPRS, Edge, UMTS). As a result, the mobile network is gaining performance and the data flows faster. The 4G offers a very high mobile speed compared to the two previous generations. On the other hand, 3G offers an improved bit rate and significantly better than 2G. With these generations of mobile phone standards, the customer benefits from a good experience since these higher speeds improve the quality of the existing service and allow new uses (mobile internet, television, etc.).
