Public private partnerships (PPPs) are, of course, necessary to get in the additional 100 billion dollars of investment, but having said that, there must be clear ground rules to make PPPs a success. Let the government confine its ambit to (a) rational spectrum release, allocation and pricing; (b) provision of land required for towers, laying of fibre optics and other infrastructure; (c) data security etc, giving a free hand to the private operators to handle all operational and pricing issues. They are all — Indian and foreign — a mature lot by now and, in any case, we have an excellent regulatory mechanism in Trai. God willing, we will succeed in realising our dreams.
