For the past four years this technology is maturing and in time we will see much deployments everywhere in the world through this technology.Though its maturing we have seen much developments in this technology like the lte-a and lte-u and the recent being the multifire .
On the handset space this technology is getting implemented slowly with handset manufacturers slowly launching volte phones around the world and as the handset ecosystem building .This problem is better taken care of.This would help the operators to roll out 4g networks all over the world.This will pace up the 4g launches in most countries. And we would soon be on the latest technologies.
In india the leading operator reliance jio is yet to launch with the news of commercial launch being on april with its differentiating factor been the voice over lte. It has been in much of the news for its latest technologies. Other operators have already launched 4g with its lte network in india like airtel being the first to launch 4g network and it has launched in an around 296 towns in india .with other operators like idea and Vodafone launching 4g recently .
So for the end user in india data would be cheap as competition gets intensified and tariffs would fall to new low post the 4G launch.
