The solar blind ultraviolet communication is a new technology which bases on atmosphere scatter and absorption. The wireless ultraviolet (UV) communication technology has received great attention for either short-range high data-rate services or medium-to-large range low-rate sensing applications. This paper described the characteristics and the main atmospheric factors affecting LOS (line of sight) and NLOS communication. Then described the principle and properties of UV communication link. Established the geometric and mathematic models of NLOS link of UV communication system and analyzed the receiving energy of a detector in UV communication system.It studied several important problems of the solar blind ultraviolet Ad hoc networks. These problems included atmospheric characteristics of UV communication, network access control technologies and network routing technologies. These technologies will be widely applied in the commercial and military sectors.
