Few things triggers more discussion than terms and definition. On one hand, you have a group of professionals that believe that the usage of a term has to be defined strictly in technical terms, and if a technology doesn’t meet the definition to 100%, it is non-compliant. Don’t say it is 4G, if it is not compliant to ITU’s definition, they claim.

The other camp, and I belong to this group, simply say that the new generation of technology is defined by both technical and commercial means. The 4th generation of mobile infrastructure is underway. LTE has a completely new air interface and a completely new core. In practice, the backhaul segment is also re-engineered. This is a huge new investment by mobile operators and the consumers have to buy new handheld devices. A new page in the history book of mobile infrastructure is being turned. I call that 4G.

The debate continues though. You can make your opinion heard here.  Or you can consider contributing to the wikipedia definition of 4G.
