Finally the area and power estimation report is discussed. Which work similarly to fiber optic links, except the beam is transmitted through free space While the transmitter and receiver must require line-of-sight conditions, they have the benefit of eliminating the need for broadcast rights and buried cables. This paper includes analysis, optimization, and design and system level development of signal transformation between satellites or any two sources. Laser communication is one of the key area in wireless Communications. After these experiments, ground-to- OICETS laser communications experiments including four optical ground stations (OGSs) were conducted and laser beam propagation data were acquired. In Japan, the Optical Inter-orbit Communications Engineering Test Satellite (OICETS) developed by the Japan Aerospace Exploration Agency (JAXA) was launched in August 2005 and a laser communication link with the SILEX terminal was successfully established. In Europe, the European Space Agency (ESA) in its Semiconductor Laser Inter satellite Link Experiment (SILEX) has routinely used a 50Mbps optical communication link twice a day between a low earth orbit (LEO) and geostationary earth orbit (GEO) satellite since 2003. The benefits are due to optical waves high frequency. Another asset comes into play in free-space point-to-point links. The main driving force was that the usable bandwidth – and hence Transmission capacity – increases proportional to the carrier frequency. Communication technology has experienced a continual development to higher and higher carrier Frequencies, starting from a few hundred kilohertz at Marconi's time to several hundred terahertz since we employ lasers in fiber systems. However, recent progress in optics and laser technologies, especially in fiber optics, is ushering in an era of inter-orbit communications using laser beams. Nathdwara, India Nathdwara, India Nathdwara, India – In space, radio frequencies (RFs) are usually used for long-distance linkage.
