How do you extend/get cell coverage inside a tunnel?
I am doing a project at the moment and need as much
info as possible? What equipment to use etc?

Koos 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.
