为了向农村地区提供强大的宽带连接，印度政府根据BharatNet倡议，在全国铺设了连接农村办事处(名为Gram Panchayat)的光缆。这项工作探索了实施从这些Gram Panchayat到附近村庄的中英里网络的可行性，在那里将建立无线集群，利用电视白色空间上的LTE-Advanced，因为电视UHF频段的频率具有良好的传播特性。提出了一种比例公平的中英里网络无线资源分配方案，该方案采用了LTE-A提供的协调多点技术，满足了宽带的要求。仿真结果表明，对于小于5公里的小区协调区域，印度农村人口密度的每个终端用户可以达到1 Mbps的速率，高于印度电信管理局(TRAI)规定的512Kbps的目标速率。
With an intention to provide robust broadband connection to rural areas, Government of India is laying out optical fiber cables across the country connecting the rural offices (named Gram Panchayat) under the initiative BharatNet. This work explores the feasibility of implementing a middle-mile network from these Gram Panchayats to the nearby villages, where wireless clusters will be set up, using LTE-Advanced over TV White Spaces owing to excellent propagation characteristics of the frequencies in TV UHF band. A proportionally fair radio resource allocation over the middle-mile network is proposed that uses Coordinated Multipoint Technology offered by Long Term Evolution — Advanced (LTE-A) which satisfies the broadband requirement. The simulation results have shown that for a cell radius of Coordination Region below 5 km, a rate of 1 Mbps per end-user for rural population density of India is achievable, which is more than the 512 Kbps target rate prescribed by the Telecom Regulatory Authority of India (TRAI).
