RTLS and IPS


ZoneRTLS

ZoneRTLS is the optimal tradeoff between cost and performance, for real-time estimate of presence and position of people and assets in operating environments.
Fixed BLE receivers use smart antennas that reduce multipath effects, allowing for a more stable RSSI (Received Signal Strenght Indicator) computation. A positioning engine, based on trilateration algorithms, provide reliable estimate of BLE tag position with accuracy of a few meters.
ZoneRTLS is the right choice for real-time tracking and localization of people and assets in plants, warehouses, hosptials, and for presence/access control.

Architecture

Fixed anchors (antennas are BlueBeacon Gateway D/W for indoor, BlueBeacon Gateway O for outdoor) are installed at known positions inside the environment where localization is required. Antennas are installed on the ceiling or on walls for indoor systems, on poles for outdoor systems. Density of antennas depends on the required accuracy in a certain zone: a rule-of-thumb is to use inter-antenna distance 3-to-5 times the required accuracy.
Each antenna receives the signal from BLE tags, and computes RSSI. Antennas are connected through LAN/WLAN to a local server where the Zone Positioning Engine (ZPE) is installed. ZPE integrates advanced algorithms based on trilateration, that allows to compute tag position from RSSI information from each antenna. Also, an estimate of the error is provided. Thus the tag location is actually a circular area centered on the estimated position.
ZPE provides REST APIs in standard JSON format, that allows to get tag(s) position in real time.

Main features

Typical positioning accuracy around 3m . Accuracy demands can vary from one area to another and can be controlled by altering the number (density) of antennas (accuracy tipically ranges from 1/4 to 1/3 of antenna inter-distance).
Location update rate of up to 1 Hz and latency down to 1 s . Update rate and latency are excellent for all use cases where (position-time) information is required (e.g. tracking of assets, access control, room presence control, ...).
ZoneRTLS is easy to integrate into existing systems with pull APIs, that offer standard JSON/REST format.
Wired anchors available in several options: LAN for data communication, 5Vdc for power; WLAN for data communication, 5Vdc for power; PoE LAN for both power and data communication.
Long battery-lifetime tags : power consumption of the BLE tags are optimized for low energy consumption.
