After introduction of the 3G services, there is the move for the 4G. It is reported that the major private mobile companies are preparing for the launch of 4G by the end of 2012. Though  customers have taken 3G services, many of them are stated to be inactive. The reason seems to be that most of the important regular  activities can be done by the 2G itself or so. However, the 4G may be different.

What about BSNL and MTNL. is there any preparation by them with regard to 4 G services?
