GSMNetworkOverview

SmallFormFactor

• Integrated BSC and BTS improves stability over VSAT

• Low power requirement -- POE

• Simple to configure and deploy

• Integrated GPS receiver

• Up to 12 active calls, plus SMS and 2.75G “EDGE” data

• Can limit max simultaneous calls as needed

• 8kb/s per call and 5Mb/month “idle state” usage.

VSATchallenges

• QoS – Virtually no support for QoS by the VSAT vendor

• Heavy use of Address/Port Translation

• Crazy firewalling

• Bandwidth – typical available bandwidth is 128kbit/s (for the entire vessel)

• RTT is way over 900ms

• Jitter is way over 200ms

• Packet Loss can easily go over 1%

• Non VSAT based systems: Inmarsat Fleet Broadband and Thuraya
