I'm looking to get a direct connection between an office and a flat across the street. The flat will be using this as its internet connection so VPN is out of the question.
I'd like to make the connection with two antennas that I would put in the windows; there's perfect line of sight, but three layers of glass in the way. Distance is about 100 meters.
- I'd like it to be cheap. The cheaper the better.
- I'd like it to be fast. At least 10Mbps, although 50Mbps would be nice.
- I'd like it to be reliable in that I wouldn't need to fiddle with the antennas every week.
- Low latency (under 100ms) is a major plus.
Which hardware should I get to do that? Are there risks in this approach that I should be aware of?
