Hi, I have read up until my head hurts......some advice please from those that know !!

I need to provide internet to a second property 150 metres away with clear line of sight. This is for streaming video and requires good up and down.

Plan is cpe210 set to access with poe cat 6 to roof from fibre router. Receive on cpe210 set as ap router (second ssid) on window wall (for wifi) Cat 6 to tv box.

There are a dozen or so wireless aerials / transmitters for internet by radio in the immediate area. I am told that interference to or from these is possible and that without being able to turn the transmit power down there is a danger of my blocking their signals.....all advice gratefully received.
