I've had a small wired/wireless network setup in our office for many years. I now need to connect the computers on that network with some new computers that are literally "across the street" in another building, less than 150 feet away. I'd love to make it a cabled connection but that is proving to be very impractical, so now I'm settling on a wireless connection.
I'm somewhat familiar with access point and bridge hardware, although I'm not entirely sure when one is needed/required over the other. I can easily get a run of ethernet from our current router to whatever device I might need. I would like to find devices that will not suffer any significant signal degradation over the proposed span between buildings. Oddly, most of the off-the-shelf access points all seem to have this problem, perhaps because of a significant amount of metal and concrete in the exterior walls of both buildings. Likewise, the signal is very different from one corner of the new building to another.
I'd like to know if anyone here has a recommendation for any type of hardware that would facilitate getting a much stronger signal at the "remote" building, and what would be needed/desired there to complete the connection. I've seen all sorts of things advertised from $50 to $5000 but don't really have a feel for what is truly necessary.
Any help would be really appreciated.
