Hi, Stewart, What does "LI" stand for? ISL is not mature enough for real adoption. The academia research suggested to use laser instead of microwave. When laser is used for ISL, there should not have spectrum license issue, I don't see the ITU or USA has spectrum allocation for the frequency of laser (400THz~700THz).

What I can guess now is that most of current technologies (with enhancement) can be used, but some new technologies might be needed to solve the satellite specific issues, such as fast mobility, frequent topology changes, constraints in satellite power, security in open space, etc. It is up to the community to decide what new technologies and what new protocols will be developed.

mp;reserved=0 Abstract: This document presents the detailed analysis about the problems and requirements of satellite constellation used for Internet. It starts from the satellite orbit basics, coverage calculation, then it estimates the time constraints for the communications between satellite and ground-station, also between satellites. How to use satellite constellation for Internet is discussed in details including the satellite relay and satellite networking. The problems and requirements of using traditional network technology for satellite network integrating with Internet are finally outlined.
