India’s largest auction for 5G airwaves has ended after seven days, potentially setting the stage for a battle of supremacy over India’s digital future between two of Asia’s richest men – Gautam Adani and Mukesh Ambani. The government drew bids worth approximately $19bn from the three current players Mr Ambani’s Reliance Jio or (R-Jio), Vodafone Idea and Bharti Airtel – and from a fourth, new entrant, Adani Data Networks. The introduction of 5G in India is likely to usher in a new era of high-speed internet, allowing video downloads in seconds and enabling the use of advanced connected devices through cloud computing technologies. Is 5G safe for human beings?
