Mobile Data Networks Understanding 2.5G vs 3G vs 4G

Real 4G comes? Let’s understand what real 4g and fake 4g.

Some people call HSPA+ as 4G, actually there is a real definition of 4G networks.

Ever since Some carriers launched their HSPA+ 4G data services in some countries a lot of people have been saying “it’s not ‘real’ 4G”. But what is ‘real’ 4G anyway? Who decides what 4G ‘is’? Let’s look at the mobile networks that have been deployed, from GPRS 2G to 4G HSPA+.

Just to answer the question of who controls the classification “4G” – the International Telecommunications Union (ITU), a body created under the United Nations regulates the global telecommunications industry. One of the core mandates of the ITU is to establish worldwide telecommunications standards, and they determine the official classification (2G/3G/4G) of mobile data networks such as GPRS, EDGE, HSPA+, WiMAX, etc.
