Satellites:
ISLs: 7 - 10 Gbit/s

Three kind of “terminals”:
Provider / Control Center with Feeder Link: 32.768 Mbit/s

Portable Terminal: 2.048 Mbit/s
Mobile Terminal: 384 kbit/s

Simulation Assumptions & Restrictions
Channel usage continuous (not in 16 kbit/s steps)

ISLs
not bottleneck; true for “good” routing

delay uncertain (see later slide), depends on routing
included in “final” simulation phase
No reduced throughput due to “double-slot FEC”
Right now: “single-hop” scenarios with different bit rates
