Location Aps Malfunctioning; Empty Rf Fingerprints; Duplicate Rf Fingerprints - Nortel 2340 Configuration Manual

38 Nortel WLAN Location Engine 2340 Web GUI
The report shows the evaluation for each locale selected. For example, here is a sample report for the 3 different Locales:
The report flags following types of problems and indicates the fix:
• Malfunctioning Location APs, not enough Location APs
• RF Fingerprints the Tracking Engine has trouble distinguishing
• Human error (e.g. RF fingerprints that are too large/small, duplicate, or for which no RF data was captured). Before
moving on to the walkthrough stage, problems can be addressed and the report rerun until the report indicates that
there are no problems.
The following sections elaborate on the causes and suggested responses to each of the problems the Evaluator is able to
catch.

Location APs malfunctioning

This error appears if a Location AP that can be reporting has failed to deliver consistent data.

Empty RF Fingerprints

The Calibration RF Fingerprints page allows you to name RF fingerprints and bind them to locales before calibration, so
that the capturing of RF Fingerprint data can be handled by a different person from the person who is selecting the locale
and RF Fingerprint names. This opens up the possibility that some RF Fingerprint names will be entered into the system
but the Tracking Engine will lack the required RF data. If this happens, then the missing RF Fingerprint data can be
captured.

Duplicate RF Fingerprints

Duplicate RF fingerprints are the result of two types of human error:
• Two of your personnel have independently captured RF data for the same RF Fingerprint
• Calibration is occurring at a date after the names have been entered and bound to locales, and the wrong RF
Fingerprint is selected from the drop down list (e.g. the person is in Conference Room A, but selects Conference
Room B from the list). In the first instance, all duplicate RF fingerprints can be deleted; in the second, the RF
Fingerprint can be bound to the correct locale and new data captured.
