| how would you stay online? If you are on a moving train, wouldn't a wifi signal continuously drop out and need to renegotiate every time you pass an access point? Or is this mainly for just the stations when you might be stationary? |

Hingham, MA | That's what I was wondering- MBTA Commuter Rail has Wi-Fi, (free to everyone, even) but it's provided by at&t (which defaced the carriages with its horrifyingly terrible logo and orange), which has a cellular network and so the Wi-Fi is provided by routers in each carriage... something like this would seem to make more sense. |

Princeton Junction, NJ | AT&T can do it at a low cost because it owns the cellular network. Cablevision only owns cable lines, and it's pretty hard to connect a cable line to a moving train. |

Remember metricom ricochet? They used transmitters on utility poles. |
