I need to get two buildings hooked up through a wireless connection and have a fair bit of concrete (not real worried about), steel and insulation. Now, there is a high amount of security that is needed to be in place, which is what's making me lean away from a standard omni-directional
802.11G antenna. I was thinking that a pair of low power directional antennas may do the trick and for them to just be placed on the out side of the buildings, or even inside if the signal reaches.My question is how narrow is the wireless field? The building is about
50ft away, not real far, but I want to be very careful that the wireless signal is not going right down the block. My other ocnsideration was using an infrared connection between the two buildings, but have found little in terms of products that will have an "ease of use" in terms of connecting to the existing network.
