A transmitting antenna with, for example, 40 watts radiated power on a 20-30 meter high mast can reach, depending on orientation, a larger area (e.g., 30 plots) at a distance of 200m with an average of 200-500µW/m². If I have a WLAN router in the technical room, the power in the immediate vicinity (0.5m distance) is about 500-1000µW/m², but the power decreases significantly with each meter of distance. A partition wall made of perforated brick or concrete slab makes a big difference here, as it significantly dampens the radiation cone of the router early on. For example, in my case, less than 1µW/m² from the router reaches the bedroom located opposite on the upper floor (concrete ceiling) in the house. This is just enough to load simple pages. In contrast, without protective coating during the interior construction, I measured over 200µW/m² in the bedroom from the mobile phone mast, which acted permanently on the area. The decisive factors are not only the transmission power but especially the orientation of the radiation cone, the duration of exposure, and the line of sight to the transmitter.No, that's correct. The emitted radiation is actually higher!!!
