We played with wireless calculators a little, and came up with these tables.
The tables are based on perfect conditions – interference, weather, alignment will affect your real life results.
The data was taken from the product specifications, and entered into wireless calculators.
The table shows the max distance if you want to get max data rate at 802.11ac or 802.11n, and the max distance if you don’t care about speed.
We used -70 as the signal for the high distance result, if lower signal is acceptable, you will get bigger distances.
