Abstract
A significant barrier in providing affordable rural broadband is to connect the rural and remote places to the optical Point of Presence (PoP) over distances of few kilometers. A lot of work has been done in the area of long distance Wi-Fi networks. However, these networks require tall towers and high gain (directional) antennas. Also, they work in the unlicensed band which has Effective Isotropically Radiated Power (EIRP) limit (e.g. 1 W in India) which restricts the network design. In this work, we propose a Long Term Evolution-Advanced (LTE-A) network operating in TV UHF to connect the remote areas to the optical PoP. In India, around 100 MHz of TV UHF band IV (470-585 MHz) is unused at any location and can be put to an effective use in these areas. We explore the idea of multi-hop topology for the proposed network. We also compare the performance of the multi-hop network with the…
