Free Space Optics (FSO) is a major hot topic in communication systems nowadays; it's a technology that uses light beam propagating from the transmitter through Free Space to transmit data received at the other side of the two point communication system. FSO is often referred to as Fibreless Optics or Optical Wireless Communication. It can be considered as an Optical Fiber replacement especially when the physical connections are impractical due to several considerations. Rapid increase of Wireless communications applications are usually faced by many of obstacles such as Bandwidth regulations, Power limit and high data rates.
