Long range wireless for data and voice connectivity is being considered as a viable and affordable solution for rural India. Typical user cannot spend more than Rs. 300 (max) per month for Internet. There is a need for affordable and easily available system, using which broadband access can be spread to every village in India. We present one such solution, using cheap 802.11b chip-set but modifying the MAC for longer range, support for QoS and better efficiency.
