Eforthink’s RTLS solutions integrate multiple location finding devices and methodologies, including:
● UWB uplink/downlink ToA and TDoA.
● AoA and RSSI.
● GNSS, inertial navigation, and sensor fusion technologies.
Key advantages:
● Versatility: Compatible with diverse RTLS technology configurations, from standalone UWB base stations to hybrid systems.
● Customization: Tailored solutions for specific scenarios, such as combining real-time location tracking with environmental sensing.
● Scalability: Supports seamless integration of Personnel Location Tags and asset trackers across industries.

These terms describe the spatial resolution of location finding devices:

Uses 802.15.4g SubG (920–925MHz band, 200kbps rate, ≥1km range). Outperforms LoRa in data capacity, supporting dense location finding devices (e.g., UBeacons) for high-precision RTLS real time location system coverage.

Indoor positioning systems rely on radio signals, acoustic, optical, or inertial navigation technologies to determine location.
Common RTLS technologies include:
Radio-based protocols: UWB, ZigBee, LoRa, and WiFi.
Positioning methods: Time of Arrival (ToA), Time Difference of Arrival (TDoA), Angle of Arrival (AoA), Received Signal Strength Indicator (RSSI), and phase-based ranging.
Differences between technologies are determined by parameters such as:
● Accuracy: UWB location technology offers centimeter-level precision, while AoA or WiFi typically provide meter-level accuracy.
● Power consumption: AoA and LoRa excel in low-power applications, whereas UWB prioritizes high performance.
● Coverage and scalability: WiFi suits large areas, while UWB-based RTLS is ideal for localized, high-accuracy tracking.
For example:
Mining operations may use UWB ToF (Time of Flight) for Personnel Location Tag tracking.
Hazardous environments might combine RSSI with UWB TDoA to balance precision and low-power deployment.

Traditional UWB:
● Uses Time-of-Flight (TOF) between tags and base stations.
● Relies on wired connections (network cable/fiber) between base stations and servers.
● Combines UWB signals with ZigBee communication.
UBeacon (Eforthink Innovation):
● Integrates RTLS Technology with TOF ranging between tags and beacons.
● Transmits data via 915MHz ZigBee to servers (fiber/4G).
● Combines UWB signals with AoA, reducing wiring costs and enabling flexible deployment.

Dual-technology synergy: Combines UWB’s centimeter-level accuracy with AoA’s cost efficiency.
Scenario-based optimization: Deploy UBeacons in high-precision zones (e.g., hazardous areas) and iBeacons in low-precision zones (e.g., warehouses).
Seamless switching: Tags dynamically switch between UWB and AoA for uninterrupted real time location tracking.

Lower Deployment Density: UBeacon covers 0–80m vs. AOD’s 10m, reducing device count by 75–80%.
Superior Stability: UWB resists multipath interference, maintaining <10cm accuracy in metal-rich environments.
Flexible Installation: Wall/pole-mounted UBeacons avoid ground obstructions, unlike AOD’s central-floor placement.
