You can scan the broadcast vicinity to see if there are any other access points broadcasting nearby. Running a site survey allows you to see if there are any rogue access points in the area. A site survey detects any access points emitting a beacon in the area and records the following details about each detected access point:
Index: Entry number.
SSID: Service set identifier (SSID).
MAC Address: MAC address.
RSSI: Received signal strength indicator (RSSI). The RSSI numbers are in decibels (dBs) that indicate the signal-to-noise ratio (SNR). The SNR is the signal level (in dBm) minus the noise level (in dBm), which results in a value representing signal strength.
Channel: Broadcast channel of the access point.
Note: Depending on your network, a site survey can take up to 60 seconds to complete and disrupts wireless network traffic.
