—Broadband penetration in developing countries such as India is still very low, especially in rural areas, because of the prohibitive cost of laying cable and fiber. Recently, wireless solutions based on Wi-Fi have been proposed as a cost-effective solution to bridge the last-mile problem. However, Wi-Fi normally operates in the 2.4 GHz band and above,(More)
—In this paper, we present ROSALNet, a low-cost TDM mesh network which is designed to opportunistically exploit TV white spaces (TVWS) to provide broadband Internet connectivity to remote rural areas.

We present ROSALNet, a low-cost TDM mesh network which is designed to opportunistically exploit TV white spaces (TVWS) to provide broadband Internet connectivity to remote rural areas. Exploiting TV white spaces for broadband connectivity can potentially bring down the cost of wireless networks to a more affordable level. ROSALNet is implemented on(More)
