Have a building that needs internet access and the the people that were inside said that using their smartphones would be fine. Here is the problem: The building is steel and they cannot get cell service AT ALL. So of course no internet with phones. Is there a solution to this by placing an antenna or something outside of the building and running a cable to a wireless router inside that the phones can hook up to WIFI? Or is there a better solution for this scenario? I was hoping not to have to pull in an internet line that is not there at the moment.
