Higher price of airwaves, willingness of customers to switch to 5G and pay more, and the capital expenditure to be incurred by telecom companies to deploy the technology are among some of the key factors which will determine successful implementation of 5G technology in the country, India Ratings and Research (Ind-Ra) said.
