In 1983 the microwave link was used for one tv channel, but computer processors are thousands of times faster now so many tricks can be used to increase the bandwidth,
real time compression can be used,this would have been impossible in the eighties
The faster processor also allow the microwave to be changed more times per second.
The low powered Raytheon units can do 20megaBYTES per second, so high powered towers must be able to do more.
The satellite internet must only work when the boat is perfectly still? If I Bob's up and down it would probably lose its signal right?
The coverage area for this boat internet seems to hug the coastlines of several countries and actually mimics the flat earth map!
Ie hardly any coverage in the southern hemisphere,except next to land!
