Wi-Fi Low RSSI Threshold
If Cisco TAC instructs you, use the following setting to change the threshold for the Wi-Fi low Received
Signal Strength Indicator (RSSI).
Table 79: Wi-Fi Low RSSI Threshold
Description
Default
Field Type or
Choices
Field
Voice quality can degrade if the Wi-Fi
signal is too weak. The RSSI changes as
the user moves closer to or away from the
connected AP. The RSSI threshold value
setting is the RSSI level at or below which
the phone seeks a better AP. The phone
uses many attributes of an AP to determine
if it is a good candidate including the
current load on the AP, the available
bandwidth on the AP, and channel.
Sometimes the best AP may have an RSSI
value lower than other candidates.
Consult Cisco TAC before you
change the RSSI threshold
value.
