It has been almost two years since Bharti Airtel launched 4G services in India. Launch of the fourth-generation of mobile telecommunications had come at a time when 3G was still in its nascent stage. While 3G coverage has grown significantly, 4G seems far from becoming mainstream. Though Airtel has rolled out 4G in some more circles, other telecom operators such as Aircel, Videocon Telecom and Reliance Jio are likely to launch their 4G services around year-end or starting next year. Deployment of 4G network in India is certainly not going to be easy as the telecom operators face the challenge to launch a new network along with improving the existing 2G and 3G networks in the country.
