Ultraviolet (UV) communication can be operated in non-line-of-sight (NLOS) mode. In NLOS mode, UV communication systems are more adaptable to complex terrain, and they avoid the need for line-of-sight (LOS) wireless laser communication. Compared with radio frequency communication, UV communication also has the advantages of resistance to eavesdropping, low position discrimination, omnidirectionality, and strong anti-interference ability; it meets the requirements of tactical communication.
