        abstract = {In recent period of communication there is a necessity of structures with high capability and bandwidth. This is done by means of the non-fiber optics based gadget recognized as free space optical communication device. These systems which are reliant upon optics in free area, does no longer require any license for its operation. Free space optical (FSO) wi-fi communication has emerged as a possible generation for bridging the distance in current excessive date charge fiber network and as a temporary backbone for swiftly deployable mobile wi-fi communication infrastructure. Free space optical communication gives the capacity to ship massive amount of data security over slight distances without the fee of laying fiber optic cable. The era is useful in which the physical connection of the transmitter and receiver locations is hard. These sturdy structures which establish communication links by way of transmitting laser beams immediately through the surroundings, have matured to the point that mass produced fashions are now to be had. FSO device offers many functions among them being the low-begin up and operational fee, fast improvement and excessive fiber- like bandwidth. In this paper first component introduces the FSO device, its advantages, and risks its packages. Second part informs about the demanding situations which a FSO system faces while running. The demanding situations faced with the aid of FSO device is atmospheric attenuation. The atmospheric attenuation is caused by the fog, smog, rain, smoke, hen flap and many others.},
