Communication to a distance more than 1Km which is NOT a line of sight, natuarlly requires more power with matched antennas, and in India transmitting more than 0.5 watts except for educational purpose or remote controls, is illegal and you are governed by Wireless planning and co-ordination New Delhi.

All right, but who said the guy above is from India? There are countries where even 1W without license is permitted.
