| Many things have been done with Satellite
Low Earth Orbit (LEO) only have a 200 mile to 950 mile trip at the speed of light lower ping times as with the new Hughes (aka the owners of DirecTV) system they are testing now with large down and upload speeds. I have used Satellite for many types of service and it works. The government as used it for many years and major phone companies used it for most international calls for years. Ever seen the ping times on an EV-DO system 200-1800 ms and the round trip on that system is only 1 to 4.5 miles. |

| EV-DO has ping problems because each packet uploaded must be given a time slot by the NOC's computers (which control many cell towers and control the hand offs between them) before it can be sent. So you need a couple round trips just to send the first packet in TCP 3 way handshake. |
