Ultra-Wide Band and BLE for real-time tracking
PRODUCTS
One-dimensional location tracking for underground mines or factory tunnels using the reverse RTLS algorithm for BLE beacons
Main Advantages
- Much lower costs, no cabling is needed for RTLS devices, good scalability for tracking thousands of workers.
Accuracy
- 10-20 meters
Range
- 60-80 meters
Scalability
- Good scalability – tracking thousands of workers per location. RTLS device density depends on the WLAN capacity only.
Power Consumption
- Low-power BLE beacons, up to 5 years on a single battery charge.
Location tracking for underground mines or factory tunnels using one or two UWB RTLS anchors
Main Advantages
- Tracking with sub-meter accuracy using one or two RTLS anchors. Less devices, less expenses.
Accuracy
- Less than 1 meter
Range
- 50-60 meters
Scalability
- 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.
Power Consumption
- The same as UWB TWR – constant 5V power supply is needed for RTLS anchors. RTLS tags are powered by the cap lamp accumulators.
Costs
- Lower costs than typical 2D UWB RTLS installations, considering the lower amount of RTLS anchors.
Custom implementation of the double-sided TWR based on Qorvo/Decawave DW1000 chipset, suitable for 1D-3D RTLS
Main Advantages
- The best location accuracy, suitable for 1D, 2D and 3D RTLS, including the collision avoidance scenarios.
Accuracy
- Better accuracy than TDoA: 5-10 cm for static objects, 10-30 cm for moving objects.
Range
- 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.
Scalability
- 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).
Costs
- Slightly higher costs than TDoA, considering that TWR tags must be recharged on a regular basis or need to have the USB power supply.
Custom algorithm for the asynchronous TDoA without clock synchronizations for RTLS anchors, suitable for 2D RTLS
Main Advantages
- Much lower power consumption than TWR, better scalability than TWR. Good for long-term installations using batteries.
Accuracy
- 30-50 cm for static objects, 50-60 cm for moving objects.
Range
- 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.
Scalability
- 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.
Power Consumption
- TDoA tags consume approx. 50-80 times less power than TWR tags.
Costs
- For the case of RTLS tags powered by accumulators or batteries – less expensive maintenance than UWB TWR.
Remote tracking and on-device indoor navigation for Android and iOS smartphones using BLE beacons and 2D RTLS
Main Advantages
- Lower cost installation – only BLE beacons are needed for tracking smartphones. Indoor navigation for smartphones is available.
Accuracy
- From 1 to 3 meters depending upon the density of BLE beacons.
Range
- Up to 15 meters for RTLS using BLE beacons
Scalability
- Good scalability – tracking thousands of smartphones per location. RTLS device density depends on the server capacity only.
Power Consumption
- Low-power BLE beacons, up to 5 years on a single battery charge.
Costs
- Low-cost system based on BLE beacons, lower than UWB costs.
RSSI-based tracking for BLE beacons and other BLE devices
Main Advantages
- The lowest cost tracking using inexpensive hardware, such as Locator MICRO devices.
Accuracy
- Room-level or zone-level tracking, approximately 3-4 meters accuracy when in range (up to 15 meters).
Range
- Up to 15 meters
Scalability
- BLE beacon scanning per room/zone is limited to 30-50 devices per second.
Power Consumption
- Low-power BLE beacons, up to 5 years on a single battery charge.
Costs
- Low-cost system based on BLE beacons and inexpensive RTLS anchors, such as Locator MICRO.
SOFTWARE SOLUTIONS
Our UWB technologies offers a number of benefits for indoor location tracking on your mine site, including high precision and accuracy, a longer range, and the ability to pass through solid objects. BLE has the advantage of being more energy efficient and less expensive to implement, but its lower precision and range may not be suitable for all indoor location tracking applications. The choice between UWB and BLE will depend on the specific needs and constraints of the application.
