Lana and her husband just completed their 30 day cruise running a BEOS node. Here's the route data, color coded for when they were in international waters.
Coming into Vancouver
Note the route color change as we left international waters.
Trip overview - where we had connectivity
Final leg to Canada
So we pretty much demonstrated that at most latitudes we've got satellite connectivity to the BEOS network.
Currently a BEOS node with 5 peers consumes about 2.6 kbps down and less than 1 kbps up. This is easily handled by Royal Caribbean's high speed 10 mbps network.
Stay tuned when I check it out in the Atlantic Bermuda Triangle on my cruise with Bytemaster and family next month.
