I would imagine it would be quite expensive to get mobile signals through smaller tunnels and around tunnel corners. Couple that with being in an almost Faraday cage on rails, with multipath problems off any metallic ore in the rock and I guess it would make a good wireless technology testing bed for harsh environments.

Most other countries manage it fine. Go to Shenzhen and there is full 3G and 4G on all networks on the trains, in the underground stations, parking structures etc. Prettymuch total cell coverage on all the rail lines that are thru civilized areas.

IMO the telcos should be forced to sort this out as part of getting a spectrum license.

 

edit: Off topic... these video ads are driving me nuts. Now there's two... one that covers the top corner and another down the left side covering the names of the poster. When I blow them up, this old machine struggles to open the full video view so I can close them. Only would a functional MRI based advertising technology annoy me more.

 

Sounds like your computer isnt capable of operating on the internet then. Perhaps time to look at a new one?
