Positioning Engine is the heart of the RTLS system, including several patented algorithms and methods to calculate a precise real-time location withing the Wi-Fi network. It includes all necessary Adminstrator's controls over the system operation, and a flexible XML/HTTP API to export the location data to any outside system or ERP software. It provides accurate location, presence, and status information in real time for Wi-Fi tags and other supported Wi-Fi devices. PE also includes a framework to transmit messages and telemetry data from Wi-Fi tags to outside applications.

PE provides the best cost-performance compared to any other location server or appliance on the market. It can calculate a room-level location with the existing enterprise/VoIP grade Wi-Fi network, without any proprietary reader gates or additional Wi-Fi access points on site. 

To calculate the location of tracked items or individuals, PE must know the coverage area of each Wi-Fi access point, and the radio field strength patterns across the tracking area. This information is created by using Site Survey tool prior to the RTLS deployment.
