Wireless optical communication [WOC] is a recently emerging field, which gives solution for the drawbacks of radio and microwave communication issues. Optical fiber communication has already developed and accepted by its high performance such as high data capacity, speed etc. But WOC experiences atmospheric turbulence problems and distant dependent path loss. And scintillation and aerosol particles (rain, haze, fog and drizzle) bring this major challenge for the WOC system by inducing the atmospheric attenuation and scattering. The optimization of WOC system is required for atmospheric effects, fog attenuation, rain attenuation, physical obstructions, scintillations, building sway, etc. Relaying techniques are the best solution for minimizing the distant dependent loss. The idea of this optical system is so promising that this system can become the required solution to real time communication system. And this has been signified by the increasing sophistication of optical (and infrared) components and techniques, along with rapidly expanding communication requirements. Here we have made a review on various factors related to WOC and analyzed for improving its performance.Keywords: Wireless optical communication, scattering, atmospheric turbulence, outage probability, scintillation, attenuation, bit error rate
