This will be very different than the current satellite internet offerings. Currently the Geo-Stationary satellites are used which are 22,500 miles above the Earth making the signal delay in the 1/2 second range for each round trip. There can be dozens of round trips to get one page to open.
The new satellites will only be 250 miles above the Earth cutting the latency (delay) to a much more reasonable time. Due to the low altitude, they will have to go faster than the Earth rotation and in different directions so you have to have a chain of satellites that hand the signal off to each other as on rises above the horizon as the other falls below. It will be interesting to see what the net result is.
