The Situation and Scope of LTE in India

People may argue that India doesn't even have 3G in all of the areas of the country but, Airtel and Reliance have already made their move to implement the 4th Generation Long Term Evolution also known as LTE.

Airtel is the first provider in India to give LTE services in Kolkata, Bengaluru, Pune, Chandigarh, Mohali, Panchkula, Ludhiana, Jalandhar, Amritsar, Kapurthala, Phagwara, Hoshiarpur, Patiala, Nagpur, Nasik & Vasai-Virar-Nalasopara (Source)

With Aircel bring the second in India with LTE services in Tamil Nadu, Jammu & Kashmir, Andhra Pradesh, Assam, Bihar and Orissa. Reliance Jio is expected to launch it's services in March 2015 with trials starting in late December or early January 2015. According to the spectrum rules, if the stakeholders of the 4G frequency are unable to roll out LTE in at least 90% of their covered area, the Department of Telecom will have the right to withdraw those frequencies.

There are primarily 2 modes of LTE: Frequency Division Duplex (FDD) and Time Division Duplex (TDD). FDD uses 2 different bands of frequency for uplink and downlink whereas TDD uses the same band but a time gap between uplink and downlink.

In India, LTE is implemented as TDD in Band 40. In other countries where LTE is being pushed aggressively, FDD and TDD are used simultaneously. FDD currently uses band between 1 & 22 and TDD uses bands between 33 & 41. 

While buying an LTE enabled phone to use in India, make sure that it supports Band 40 or 2300 MHz for 4G. You can check that by seeing the phones specifications. As an example, you can see below that the Motorola Droid Turbo doesn't support Band 40 (2300 MHz) whereas, the iPhone 6 does. Most Indian variants that are advertised as LTE enabled support Band 40 but just to be sure, check out before buying one.
