18 Deployment metrics for different tracking typesNN47250-504 (324122-A Version 01.01)LocalesAt the maximum, create one Locale for each RF Fingerprint. A good rule is to create one Locale for each departmentinside the building, and then create one Locale for each compass direction outside the building (example:Outside-northwest).Location AP Placement/DensityThe general guideline for asset tracking is one Location AP for every 4,000 to 5,000 square feet of space. In addition, foreach building, make sure that there are two Location APs within 50 feet of the building entrance or exit.The Location AP placement restrictions are:• Use a minimum of four Location APs to ensure 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 5 meters within 3 minutes.RF FingerprintsThe minimum number of RF Fingerprints required are:• One RF Fingerprint for every 3,000 square feet.• Two additional RF Fingerprints per entrance, one inside and one outside.• Four additional RF Fingerprints outside the building, one at each compass pointFor example, a 21,000 square foot first floor of an office building with two entrances would require 15 RFFingerprints, this includes:• Seven RF Fingerprints of 3,000 square feet each• Four RF Fingerprints for the two entrances• Four outside at the compass pointsThis coverage ensures the Nortel WLE2340 can tell when a device moves across the physical perimeter boundary. If theRF Fingerprints are large, the location reported is fairly coarse.Note. Evaluate each public and semi-public space, such as lobbies and loading docks.Determine whether they can be considered as inside or outside Locales.
