Non-line-of-sight communication is particularly advantageous in urban areas where there are numerous physical obstacles like buildings, trees, and other structures that can impede direct line-of-sight paths between transmitting and receiving antennas. In such environments, signals can reflect, refract, or diffract around these obstacles, enabling communication where traditional line-of-sight methods would fail. This capability is essential for maintaining reliable connectivity in dense urban settings, where the landscape is complex and may obstruct direct communication paths.

Additionally, in non-line-of-sight scenarios, lower frequencies are often utilized, which can penetrate obstacles better than higher frequencies. This characteristic makes non-line-of-sight communication a preferred choice in cities, addressing the challenges posed by the urban infrastructure and ensuring effective and robust communication links.
