How can I make a wireless connection that spans multiple floors of an office building?
There is no WLAN technology or product powerful enough to penetrate multiple floors of a building by going through the floors. But if you use two directional antennas arranged in a line-of-site shot up the outside of the building, the connection should be a piece of cake. Use two WLAN bridges and keep the antenna cable as short as possible, or use antenna / bridge products intended for outdoor use.
