Satellite Networking Principles and Protocols
Satellite has played an important role in telephony communication and TV broadcasting services since the birth of telecommunication satellites. It is less known that satellite also plays an important role in broadband and Internet services and will continue to play an important role in the future generation networks. This is due to the satellite characteristics that make a niche position for satellites in the global network infrastructure...
