Has anyone used these by chance? Looks like they create their own 5Ghz wifi connection to handle all the traffic. Says you can expand it up to 6 wireless devices all broadcast from the same base unit. I'm looking for a way to get 2 screens on opposite sides of a church and a 3rd at the rear of the church all connected. The building is very old and running cables can't be easily done through the walls so we're hoping wireless might work.
