If you have a pretty decent signal, then something like the unit you posted would work fine, I think the protocol is WDS, many apple product do this, a couple of the portable travel routers do this and other AP's. But, this requires that this device can GET/SEE the signal we are talking about. They basically act as a repeater, whereas the other solutions act as a way to REACH the signal that is far away. In the above example, there was NO WAY I was going to be able to see/reach the signal at BI or other locations, but once I could get it, then I could distribute it.
