Optimation Free Space Optic (FSO) Design with Kim Model Using Space Diversity
JURNAL INFOTEL, 2019 The development of communication services in remote rural areas is difficult to use cable-based systems such as Digital Subscriber Line (DSL) and FTTx. One solution to solve this problem is to use a wireless system such as radio communication. Free Space Optic (FSO) communication system is a better choice compared to radio communication because of the ...
