Summit WMScanner Users Guide 79
The drawing map window is divided into two parts:
● Access Point Information - The Access Point area contains the following information about the
detected access points:
■ MAC Address - Media Access Control address for the corresponding access point.
■ SSID - Service Set Identifier for the corresponding access point.
■ Signal Strength - The average signal strength of the wireless connection as reported by the
client.
■ RSSI - Received Signal Strength Indication. This column indicates the power level of a
received signal. RSSI units are in dBm (decibels relative to one milliwatt).
■ Standard - Air Interface Standard for the corresponding access point (802.11a/b/g/n)
■ Noise - The radio power (in dBm) of the background noise on the frequency that the AP is
operating on. When the client is in promiscuous mode, the client constantly changes
frequencies and measures RF for all channels that it is scanning. The noise value is collected
from the perspective of the client (location wise), while the scanned channel data corresponds
to the advertised AP channel.
■ SNR - Signal to Noise Ratio. This is the signal power in dBm minus the noise power in dBm.
■ WEP - Wired Equivalent Privacy. This column displays whether the WEP setting for the
corresponding access point is enabled or disabled.
■ Channel (Ext) - The primary and extension channels for the AP. The extension channel is
indicated in parentheses. Whenever an AP is indicated to work in an extension channel, it
means that the AP will transmit/receive in 40 MHz channel width.
■ Channel Width - The channel widths the AP is capable to work in, 20 MHz only or dynamically
alternate between 20 MHz or 40 MHz.
■ Accepts GF - This column indicates whether the AP is capable of receiving 802.11n frames
transmitted in the Greenfield format. When frames are transmitted in the Greenfield format,
they are transmitted without any protection from legacy APs.
■ Has Legacy Client - This column indicates whether a legacy client is associated with an 11n AP
or not. This field will be indicated as “N\A” (not available) for legacy APs and as “Yes” or
“No” for 802.11n APs. This column indicates that the BSS is working in the HT Mixed mode.
● Marker Settings - Provides the following marker options:
■ Single Marker - In this mode, select an area of the drawing map to identify your current
location within the building.
■ Track Run - In this mode, select an area on the screen with the mouse where you are currently
standing within the building.
