Abstract :
The paper provides a comparison between terrestrial and mobile satellite based broadband network planning for use in feeding terrestrial wireless local loop (WLL) systems. After presenting a typical WLL urban scenario the terrestrial design for connecting the WLL nodes to a terrestrial backbone network via two pops (point of presence) is given. This design is followed by introducing the envisioned TELEDESICTM broadband mobile satellite network including its technical features and limitations. Based on this mobile satellite broadband network a design for connecting the same WLL nodes as in the first case is provided. Special limitations due to the characteristic requirements of the 20/30 GHz transmission environment as well as dynamic channel allocation issues are taken into account
