The Fresnel zone of the radio beam is an ellipsoidal region that surrounds the visible line of sight directly.

The antenna installation position should ensure that the two nodes of the link are visible, and try to ensure that there is no obstruction in the Fresnel zone.

Two nodes of the site link are visible, and the Fresnel zone boundary is blocked, which will not affect the link transmission effect.

The distance between the stations is 2 kilometers, and the radius of the Fresnel area is about 6 meters.

The STA listens to each channel beacon and finds that AP2 satisfies the roaming condition and sends a probe request to AP2.

AP2 responds by sending a response on channel 6 after receiving the request in channel 6 (the channel used by AP2)

The STA sends the 802.11 disassociation information to the AP1 through the channel 6 (the channel used by the AP2), and the association between the user and the AP1 is released.

The STA sends an association request to AP2 through channel 6, and AP2 responds with the association response to establish an association between the user and AP2.
