RSSI threshold setting is recommended when deployed in high density scenario. Wireless access for client with lower RSSI value than configured setting is forbidden to access. By default, RSSI threshold is disabled (0). RSSI threshold can be applied to 2.4G band or 5G band separately. Recommended 2.4G (5), 5G (10).
Roaming RSSI is used in conjunction with 802.11k and 802.11v. Clients that support these protocols will be informed with sufficient information to which AP to roam to when the threshold is breached. Roaming RSSI is applied to 2.4G band and 5G band separately. Recommended 2.4G (10), 5G (15).
The relation between signal strength and configured RSSI is = (RSSI – 96) dBm
