Deployment metrics for different tracking types 19Nortel WLAN - Location Engine 2340 Configuration - Using InterfacesContent DeliveryContent Delivery deployment tracks devices using an existing wireless network infrastructure. This type of deploymentrequires more precise location information, pinpointing devices to a smaller Locale. Therefore, this type of trackingrequires a greater number of Location APs, Locales, and RF Fingerprints.LocalesFor this variable grained tracking, you need to initially determine which areas require content delivery and which areasrequire less precise tracking to create Locales accordingly. For example, if you decide to have content delivery trackingin Marketing and Sales then device tracking or tracking is not required.Location AP Placement/DensityInstall Location APs in dense deployment areas where more accuracy is required, that is one Location AP for every3,000 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 therange of 3 meters within 3 minutes.RF FingerprintsThis 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 transitionpoints to enable the Nortel WLE2340 to correctly report the location of a device when it passes through the transitionfrom one Locale to the next. There is some flexibility for the numbers of RF Fingerprints that can be utilized to fine tunethe tracking.Note. For buildings that wrap around and enclose space (outside), such as buildings inthe shape of the letter ‘C’, a corresponding increase in the number of Location APs isrequired.
