Satellite Communication Networks Performance
A number of serious consortiums develop satellite communication networks. The paper is to service personal communication users almost everywhere on earth. The inter satellite links in those projects use microwave radiation as the carrier. Free-space optical communication between satellites networked together can make possible high-speed communication between different places on earth. Some advantages of an optical communication system over a microwave communication system in free space are smaller size and weight, less transmitter power, larger bandwidth, and higher immunity to interference.
