我们也可以选择无线微波回程，但这必须保持发射塔在同一条视线上，而且在一些情况下数据必须通过有线网络传输。
There is also the option of a wireless microwave backhaul, but it requires cell towers that are in the same line of sight, and at some point the data still has to go wired.
利用大气对光的散射作用可以实现非视线通信。在单次散射假定下，研究了非视线光散射通信系统的大气传输模型。
Based on the assumption of single-scattering, atmospheric propagation model of non-line-of-sight optical scattering communication system is studied.
