A couple wireless carriers in India, Airtel and BSNL, are working with Nokia on the next generation of wireless technology. Even though the country is still lacking in 4G coverage, both providers have signed agreements with Nokia to upgrade their infrastructure to support 5G.

Thoughts behind these MoUs [memorandum of understanding] would be to introduce 5G here, and what are the steps required for the same, besides identifying applications to define the target segment, which will lead to a complete 5G strategy for telcos.

Testing of 5G capabilities has already begun in some countries and the roll out of 5G could begin within five years. Airtel and BSNL clearly want to be prepared.
