INDUSTRIAL RTLS
In-house research and implementation of RTLS algorithms using UWB, BLE and other wireless protocols
Tunnel BLE RTLS
One-dimensional location tracking for underground mines or factory tunnels using the reverse RTLS algorithm for BLE beacons
Much lower costs, no cabling is needed for RTLS devices, good scalability for tracking thousands of workers.
10-20 meters
60-80 meters
Good scalability – tracking thousands of workers per location. RTLS device density depends on the WLAN capacity only.
Low-power BLE beacons, up to 5 years on a single battery charge.
Low-cost system based on BLE beacons, lower than UWB costs.
Tunnel UWB RTLS
Location tracking for underground mines or factory tunnels using one or two UWB RTLS anchors
Tracking with sub-meter accuracy using one or two RTLS anchors. Less devices, less expenses.
Less than 1 meter
50-60 meters
- Settings for longer range : 1 Hz rate – up to 120 tags, 5 Hz rate – up to 25 tags.
- Settings for higher density: 1 Hz rate – up to 800 tags, 5 Hz rate – up to 160 tags.
The same as UWB TWR – constant 5V power supply is needed for RTLS anchors. RTLS tags are powered by the cap lamp accumulators.
Lower costs than typical 2D UWB RTLS installations, considering the lower amount of RTLS anchors.
UWB TWR
Custom implementation of the double-sided TWR based on Qorvo/Decawave DW1000 chipset, suitable for 1D-3D RTLS
The best location accuracy, suitable for 1D, 2D and 3D RTLS, including the collision avoidance scenarios.
Better accuracy than TDoA: 5-10 cm for static objects, 10-30 cm for moving objects.
- Settings for longer range: best case LOS – 80 meters, worst case LOS – 60 meters.
- Settings for higher density: best case LOS – 50 meters, worst case LOS – 30 meters.
- Settings for longer range : 1 Hz rate – up to 120 tags, 5 Hz rate – up to 25 tags.
- Settings for higher density: 1 Hz rate – up to 800 tags, 5 Hz rate – up to 160 tags.
TWR tags must be recharged every 12-48 hours or powered via USB (e.g. Tag PRO).
Slightly higher costs than TDoA, considering that TWR tags must be recharged on a regular basis or need to have the USB power supply.
UWB TDoA
Custom algorithm for the asynchronous TDoA without clock synchronizations for RTLS anchors, suitable for 2D RTLS
Much lower power consumption than TWR, better scalability than TWR. Good for long-term installations using batteries.
30-50 cm for static objects, 50-60 cm for moving objects.
- Settings for longer range: best case LOS – 80 meters, worst case LOS – 60 meters.
- Settings for higher density: best case LOS – 50 meters, worst case LOS – 30 meters.
Better scalability than TWR:
- Settings for longer range : 1 Hz rate – up to 360 tags, 5 Hz rate – up to 75 tags.
- Settings for higher density: 1 Hz rate – up to 2400 tags, 5 Hz rate – up to 480 tags.
TDoA tags consume approx. 50-80 times less power than TWR tags.
For the case of RTLS tags powered by accumulators or batteries – less expensive maintenance than UWB TWR.
Smartphone RTLS
Remote tracking and on-device indoor navigation for Android and iOS smartphones using BLE beacons and 2D RTLS
Lower cost installation – only BLE beacons are needed for tracking smartphones. Indoor navigation for smartphones is available.
From 1 to 3 meters depending upon the density of BLE beacons.
Up to 15 meters for RTLS using BLE beacons
Good scalability – tracking thousands of smartphones per location. RTLS device density depends on the server capacity only.
Low-power BLE beacons, up to 5 years on a single battery charge.
Low-cost system based on BLE beacons, lower than UWB costs.
BLE Zoning
RSSI-based tracking for BLE beacons and other BLE devices
The lowest cost tracking using inexpensive hardware, such as Locator MICRO devices.
Room-level or zone-level tracking, approximately 3-4 meters accuracy when in range (up to 15 meters).
Up to 15 meters
BLE beacon scanning per room/zone is limited to 30-50 devices per second.
Low-power BLE beacons, up to 5 years on a single battery charge.
Low-cost system based on BLE beacons and inexpensive RTLS anchors, such as Locator MICRO.
