AP EVAL DATA
The AP Eval Data web page contains information on each of the access point modules that the subscriber module has visibility to. For each access point module that can be seen certain bits of information are shown on this web page. An example of the information shown on this web page for each access point module:
Index: 0 Frequency: 0 MHz ESN:
Jitter: 5 RSSI: 1295 Beacon Count: 37
Type: Multipoint Avail: 1 Age: 0 Lockout: 0 RegFail 0 Range: 245 feet TxBER: 1

Descriptions of the parameters that can be useful for managing and troubleshooting a Canopy System are:
Index: each access point module that a subscriber module can see is assigned an index value for purposes of this web page only. The index number starts with 0 and increases by 1. This index is used to tell the operator which access point module the subscriber is currently registered to. For example, the first line of text on the web page says “Current entry index: 5”, the operator would then scroll down the list of access point modules to the module with “Index: 5” to view information about the link.
Frequency: displays the transmit frequency of the access point module.
ESN: displays the electronic serial number (MAC address) of the access point module.
Jitter: displays the last jitter value captured between the subscriber and access point module.
Range: displays the distance (in feet) between the subscriber and access point module. This parameter will only be valid when observing the data for the access point module that the subscriber is currently registered to.
Session Count: displays the number of times the subscriber module has gone in and out of session with the access point. If this number is particularly large, it typically signifies that there is some sort of issue with the link (i.e. non line of sight, interferers, etc.)
Out of Range: displays a counter for the number of times the access point module has seen a subscriber module who has attempted to register and has been farther away than the max range parameter on the access point.
Sector ID: displays the sector ID of the access point module.
Color Code: displays the color code of the access point module.
Sector User Count: displays the numbers of registered subscriber modules on the access point module.
Rescan APs: click on this button to force the subscriber module to redo the scanning process. The subscriber module will scan, through the frequencies checked on the Configuration web page, for all available access point modules and register to the one that provides the best results for RSSI, Jitter, and number of registered users.
