A Framework for Wireless Broadband Network for Connecting the Unconnected
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 Point to
Multipoint (PMP) topology. The results show that multi-hop network performs
much better than the PMP network. We then formulate a Linear Programming (LP)
problem of generating optimal topology and compare its performance with the
multi-hop network. Overall, the analysis implies that an optimally planned
LTE-A network in TV UHF band can be a potential solution for affordable rural
broadband
