Avalon, NJ |  This system would have worse latency than planes using 3g
If this would ever be implemented, it is kind of funny that trains on the ground would have worse latency than planes would have that are now implementing 3G systems. |

Let's see those airplane 3G systems working over the middle of the Atlantic Ocean...
Similar issue with using terrestrial cell system design for trains in the middle of nowhere. Or in a car for that matter. No coverage.

And that is because major rail corridors are parallel to major highways(the rail corridors came 1st). And major highways are almost totally covered by cell towers in the US.

| I just drove from Colorado to California and back. Although I had cell coverage most of the way with my iPhone, probably 70%+ of the time, I couldn't even pull email/surf even though I had almost full bars. Talking and SMS would work great, it's just the data was useless. (this was on EDGE and 3G) |

And major highways are almost totally covered by cell towers in the US. While most commuter and short distance train routes are well covered (even here in the west), there are still plenty of places, especially on the long distance trains where you will lose cell service. For example, many of the long distance routes in the west, ie.the Coast Starlight, California Zephyr, Empire Builder, Sunset Limited, Texas Eagle, Southwest Chief, Pioneer, Desert Wind, have several places where they are out of cell range. A highway nearby does not always mean a cell signal  Something like this, especially here in the west would be awesome!

(this was on EDGE and 3G) If you went through Wyoming that is because in Wyoming you are on a partner network, which does not allow ANY data. Texting and voice work, but there is not enough bandwidth to allow data, would be nice though. Then there are parts of Nevada that are on partner networks as well that I could also not pull any data. When I was on AT&T's network I could pull data just fine. |

The Luneberg lens is a nice design, but by its nature is often too heavy, costly, or needs too much power (to drive the feeds) for consumer applications. Been used by the military and some commerical users (DBS) for a number of years. Maybe they have something here.
Not too sure how it stacks up against against a diversity reception design (multiple receive antennas) and an adaptive receiver. |

Not so fast, the Cascadia train between Portland,OR and Seattle passes through a rural areas. Add to that there are a lot of cell phone gaps on the I-5 if G3 was offered it would be spotty at best. We in the West are not dense as the East Coast. |

1 edit | train mounted satellite NOT new, just improved
A Pic of Via rail dome.
In north America as RR conductor said there is very spotty wireless tower access for Amtrak trains (except for the northeast corridor aka: NEC), so satellite would be the way to go. Also just getting regular cellular service is a miracle sometimes unless your on a CDMA network (Verizon) but GSM (ATT) is so broken up and spotty out side of major metro areas it defeats its own advantages. Also remember this is NOT new, just improved. or neighbours to the north(Canada) Operate VIA Rail trains and have had dome based satellite internet for a few years now. This dome functions exactly like the VIA Rails domes but is only half the height. This new dome wouldn't make much of a difference if installed on Amtrak long distance train, but would probably be needed ONLY on any Amtrak train that services the NEC where height in tunnels or Penn station are limited. Bottom Line... dome Satellite is needed on Amtrak LD trains, but this new half height dome is a waist of money for North American Trains outside the NEC.
link to a VIA rail dome when first added to there trains.
