you will need a cell-phone booster, like you might use to illuminate an office area that is below ground for instance. You need a solar panel and battery pack to supply it. Then on the antenna side you need an elevated position and a small yagi beamed on the nearest cell phone base to get the down-load link sorted. Finally, on the up-link side into the tunnel you need leaky coaxial feeder from Andrew Corp.
That should do it.
