Our company is attending an expo. The building is a concrete building with a concrete roof. The 3G signal is extremely bad inside the building, so much that you loose connection. Yet when you go outside it is a good signal.
What is the best way to get better 3G signal inside for the week they are there and is mobile so that it can be packed up and brought back to the office to use again some place ells.
Keep in mind there is other companies as well, thus we can just run cables from outside to inside at our leisure or where we want to.
