Terrain and Access Issues (Mountainous, Wetlands, Private Land) Remote or environmentally sensitive locations: mountains, wetlands, or private. Understanding the variants of small cells (femto-, pico- and microcells) and the design challenges that come with each will help you find the right solution to fit your needs. This review will guide scholars to comprehend various existing and emerging interference challenges, for further. To ensure stable communication between a base station and connect with the stability of mobile devices, it is necessary to check radio communication performance and eliminate radio wave whether or not radio interference and other obstacles when installing the base station exists. Challenge 1:. This acts as the “blood supply” of the base station, ensuring uninterrupted power., competing radio signals interfering with radio propagation) and passive (e.
