The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
Receiver Start of Packet Detection Threshold (Rx SOP) determines the Wi-Fi signal level in dBm at which an access point's radio demodulates and decodes a packet. As the Wi-Fi level increases, the radio sensitivity decreases and the receiver cell size becomes smaller. Reduction of the cell size affects the distribution of clients in the network.
Note | RXSOP configuration is not applicable to 3rd radio module pluggable on 3600 AP. |
Verify information about Rx SOP thresholds for an 802.11 band by using theshow {802.11a | 802.11b} extended command.
Step 1 | Configure high,
medium, or low Rx SOP threshold values for each 802.11 band by entering this
command:
config {802.11a | 802.11b} rx-sop threshold {high | medium | low | auto} {ap ap_name | default} You can configure the Rx SOP thresholds for an access point or on all access points in an 802.11 band. |
Step 2 | Configure high,
medium, or low Rx SOP threshold values for an RF profile by entering this
command:
config rf-profile rx-sop threshold {high | medium | low | auto} profile_name |
Step 3 | View information
about Rx SOP thresholds for an 802.11 band by entering this command:
show {802.11a | 802.11b} extended (Cisco Controller) > show 802.11a extended
