Combined Atmospheric Optical Wireless Radio
At the end of the last century, the optical communication via open space – FSO (Free Space Optics) was rapidly developing. FSO has certain advantages over other means of telecommunication such as: high speed, “wireless”, short installation time, secrecy of communication. System FSO + FR (IIMs) can be used for applications which do not allow even a single loss of information. Unlike FSO + FR (IIM) the system FSO + FR (CF) is cheaper and “long-range”, but fraught with packet loss when switching from the primary optical link (FSO) to the backup FR (SCM). The main sphere of use of the system is building urban network infrastructure.
