Content Delivery; Locales; Location Ap Placement/Density; Rf Fingerprints - Nortel 2340 Configuration Manual

Content Delivery

Content Delivery deployment tracks devices using an existing wireless network infrastructure. This type of deployment
requires more precise location information, pinpointing devices to a smaller Locale. Therefore, this type of tracking
requires a greater number of Location APs, Locales, and RF Fingerprints.
Note.
the shape of the letter 'C', a corresponding increase in the number of Location APs is
required.

Locales

For this variable grained tracking, you need to initially determine which areas require content delivery and which areas
require less precise tracking to create Locales accordingly. For example, if you decide to have content delivery tracking
in Marketing and Sales then device tracking or tracking is not required.

Location AP Placement/Density

Install Location APs in dense deployment areas where more accuracy is required, that is one Location AP for every
3,000 square feet for these areas. For areas requiring less accuracy, a less dense deployment is required.
The Location AP placement restrictions are:
• Use at least four Location APs per building (this ensures accurate tracking).
• Do not install a Location AP within 10 feet of an outside wall.
• Do not install Location APs near windows or other expanses of glass that border the outside.
When using this density of Location APs in a deployment, typical precision and latency numbers can be expected in the
range of 3 meters within 3 minutes.

RF Fingerprints

This type of location tracking requires one RF Fingerprint per Locale and more for rooms in excess of 500 square feet.
As you test the tracking with walkthroughs, you may find that you need to add RF Fingerprints in certain transition
points to enable the Nortel WLE2340 to correctly report the location of a device when it passes through the transition
from one Locale to the next. There is some flexibility for the numbers of RF Fingerprints that can be utilized to fine tune
the tracking.
