If the relative altitude of wireless aps is changed into (10 meters of h3 from h1<h2<15 meters, for example, h3 is 12 meters), if not
The antenna of wireless aps work at present is adjusted, then interference, such as Fig. 5 (c) are easily produced between wireless aps
With Fig. 5 (e) Suo Shi, because wireless aps 1 are identical with the channel of wireless aps 5, and A1 and A5 is overlapped,
Then wireless aps 1 produce interference with wireless aps 5, because wireless aps 3 are identical with the channel of wireless aps 4, and A3
