Hello!
I face the problem of getting GSM signal into a reinforced concrete structure. It acts like a Faraday cage so there is not signal inside.
Due to legislative I can not use active repeater. So how can I get it inside passively?
Outside of the building a cellphone shows "full" signal. I thought I will buy two GSM antennas connect them with a coax cable. One antenna would be outside one inside. Will it work?
How much gain should antennas have? I know "higher is better" but give me a starting point so I can decide if it is doable.
edit: The nearest cell tower is only 2,5km.
