If based on standardization, there are only 2G and 3G at the moment. Any others self proclaimed 2.5G, 3.5G, 3.75G and 3.9G never existed. There are different releases and upgrades from the existing "G" from time to time. However, the standard never gives a "G" differentiation to the releases and upgrades.
1. WiMAX 2 and LTE-Advanced are 4G technologies.
2. WiMAX, HSPA, HSPA+ and LTE are all 3G technologies.
3. GPRS and EDGE are 2G technology.
The reason why there are so many self proclaimed "G" technology is more or less coming from the equipment vendors.
As the equipment vendors want to sell to the operators new equipment, they always grade it a few "G" higher than their existing one to convince them to upgrade/ purchase new one.
And also to the operator, to market their service better than existing one, they take the bait and use the higher "G" to market to their customers as well.
AND one important point is that, it doesn't matter how many "G" are there, everything comes back to average throughput per sub.
If a so-called 3.5G technology can reach a theoretical maximum of 14.4Mbps and sold to 20 people, average each will get is 700kbps.
If a so-called 4G technology can reach a theoretical maximum of 35Mbps and sold to 40 people, average each will get also 700kbps.
So what's the different between these two technologies, it's the SAME!
To operator, the more bandwidth the technology can provide, meaning they can sell to more people. But to the people, they are not getting anything extra!
This type of technology advancement will have no benefit to the user, it will only benefit the operator/provider.
You are conned if you go and subscribe because of the so-called NEW TECHNOLOGY!
