CDL-based Channel Model for 5G MIMO Systems in Remote Rural Areas

Abstract

In the fifth generation (5G) mobile networks, it is expected that users experience high throughputs with an ultra low-latency network, while a massive number of devices are connected to the network. However, in remote rural areas, there is still a large number of people that do not have access to Internet broadband. To overcome this issue, a possible strategy is to exploit the excellent propagation conditions of very high frequency (VHF) and ultra high frequency (UHF) bands by allowing a secondary spectrum reuse in the TV white space (TVWS) channels. But for that, a reliable channel model is required to perform valid coverage and capacity prediction studies. In this paper, a channel model is proposed that takes into account large and small scale fading effects, as well as the particularities of such remote rural areas. The proposed model is simple to implement and can be used to provide fast link-level and system-level simulations. Numerical simulations are provided to validate the model and a capacity evaluation is done considering single input single output (SISO) and different multiple input multiple output (MIMO) configurations.
