coverage gap

[wyfy-2015]

Hi,

While roaming the station shows no signal (lets say -80 to -84 )  bar but still seems it's connected . 

does it indicate the coverage gap ? 

Thanks

Yes, if clients shows -84dBm which is a weak signal. I would try to keep -70dBm overlap coverage from two APs in order to achieve smooth roaming

Hi,

What is the action controller takes based on the below  setting 

And  what is  "Power Threshold(-80 to -50 dBm)  "

Thanks

Refer this section of RRM whitepaper to understand how coverage hole detection works

The client will be allowed to rejoin the AP when the client RSSI value has increased to 6 dBm above the disassociation threshold. For example, if the Data RSSI threshold is -80 dBm, the client will be allowed to re-associate once the RSSI values is increased to -74 dBm.
