EAP-FAST
An EAP-FAST security method is designed for wireless environments where
both security and ease of setup are balanced together.
• Pressing the EAP-FAST button opens the EAP-FAST Settings dialog
(FIG. 107).
• The following fields are required : SSID, Identity, Anonymous Identity, and
Password
• Refer to the following Wireless Settings Page - Security Options -
Overview section on page 115 for further details on these security options.
Site Survey: The Site Survey tool allows installers to see all of the WAPs within the panel’s
communication/detection area.
• The information displayed includes: SSID, Channel, Signal Strength, Security
Type (if detectable), and MAC address of the WAP.
• From the site survey tool, a user can then select and connect to a WAP
although proper configuration of the security settings may still be required.
• Refer to the Using the Site Survey tool section on page 61 for more
information on using this feature.
RF Link Info: Sets the communication values for the internal wireless interface card.
SSID Displays the currently used SSID of the target WAP.
Channel The RF channel being used for connection to the WAP ( read -only ).
• This is determined through the WAP.
Link Quality Displays the current quality of the link ( as descriptive colored text ) from the
wireless NIC to the Wireless Access Point in real time.
• The bargraph has been replaced with a descriptions: None , Poor , Fair ,
Good , Very Good , and Excellent . Green color text indicates better
communication quality.
• It reports the quality of the signal over the air (direct sequence spread
spectrum). Even when the link quality is at its lowest you still have a
connection and with it the ability to transmit and receive data, even if at much
lower speeds.
Note: Both Link Quality and Signal Strength are applicable to the RF
connection only. It is quite possible to have an RF signal to a Wireless Access
Point but be unable to communicate with it because of either incorrect IP or
encryption settings.
Signal Strength
SNR (Signal Noise Ratio) is a measure of the relative strength of a wireless RF
connection. This indicator displays a description of the signal strength from the
Wireless Access Point connection.
• The bargraph has been replaced with a descriptions: None , Poor , Fair ,
Good , Very Good , and Excellent . Green color text indicates better signal
strength.
• Given this value and the link quality above, a user can determine the noise
level component of SNR.
Ex: If the signal strength is high but the link quality is low then the cause of the
link degradation is noise. However, if the signal strength is low and the link
quality is low the cause would simply be signal strength.
Data Rate The data rate (in Mbps) at which the panel is currently communicating with a
target WAP at (dynamic).
• As you move closer to the target WAP (and both the signal strength/quality),
the data rate increases and as the quality degrades this rate decreases.
• Data rates for 802.11b communication are: 1, 2, 5.5, and 11 Mbps.
• Ex: 802.11b has a max data rate is 11 Mbps.
