If you Google "SCPC VSAT" you'll see the geostationary equivalent of what o3b is competing with... 495ms latency, dedicated 1:1 ratio frequency allocation, FDD. Usually 2.4 meter and larger sized dishes.
o3b provides a 100/1000 Mbps Ethernet handoff from the satellite modem that us logically the same, but much lower latency and less $/month per dedicated Mbps. >From a router or network equipment perspective the two can be identical, or different... An SCPC circuit can be a layer 2 bridge between two modems, or a /30 OSPF link net, or an IP default route (your ISP owns the far end and gives you a /29 or 30 and default GW).
