These days most global roads to economic growth possibilities lead invariably to India. The latest traveller by this road is Tim Cook, who, liberally scattering praise for India, hinted at iPhone manufacturing in the country. Now we hear that Satya Nadella of Microsoft is coming to Delhi on May 30, where he is expected to push Microsoft’s White-Fi technology, using which he is ostensibly lobbying for free allotment of precious spectrum in the TV UHF bands 4 or 5 (470-590 and 585-806 MHz, respectively) for provision of broadband internet services in rural and remote areas. On the face of it, this is a noble and laudable mission, and Microsoft has been driving it for over three years in India. But if one undertakes a deeper technical analysis, one begins to see huge challenges and clearly worrisome developments.
