Bluetooth AoA	Determines signal direction via antenna arrays for improved accuracy.	High precision (0.1–1m), ideal for indoor tracking.	Requires specialized hardware and calibration.
UWB (Ultra-Wideband)	Measures the time-of-flight of radio pulses for centimeter-level precision.	Ultra-high accuracy, resistant to multipath effects.	High cost, complex installation.

Communication Protocols

Protocol	Function	Strengths	Challenges
LoRaWAN	LPWAN uses unlicensed bands for long-range communication.	Long battery life, low power, and wide coverage.	Susceptible to interference, limited bandwidth.
NB-IoT	LPWAN over licensed LTE bands. Reliable, cellular-based data transmission.	Strong coverage, secure, suitable for remote environments.	Latency, infrastructure dependency, and higher cost.

Lansitec Positioning Solutions

1. B-Mobile

Description: B-Mobile employs Bluetooth beacons fixed to staff or items, along with Bluetooth gateways placed in stationary locations. The system transmits location data to a centralized server via LoRaWAN, NB-IoT, or alternative backhaul networks.

Key Features:

• Room-level presence detection.
• Accuracy: ~3–5 meters with two-point positioning.
• Gateways act as receivers; servers compute actual positions.

Deployment:

• Gateways are mounted on walls or ceilings.
• Beacons are carried by individuals or affixed to assets.

Use Cases:

• Personnel safety monitoring in healthcare or factories.
• General asset tracking in warehouses.
• Entry/exit alerts using geo-fencing.

Pros:

• Cost-effective.
• Scalable and easy to maintain.

Cons:

• Dependent on line-of-sight and signal strength.
• Limited to meter-level accuracy.

2. B-Fixed

Description: B-Fixed flips the B-Mobile configuration: Bluetooth beacons are installed at fixed points, while personnel wear badge-like trackers. Location is determined by signal strength as tracked devices pass fixed beacons.

Key Features:

• Real-time location with geo-fencing.
• Accuracy: ~2–3 meters using RSSI.
• Transmits data via LoRaWAN or NB-IoT.

Deployment:

• Static Bluetooth beacons at gateways, walls, or checkpoints.
• Mobile units (badges or tags) are worn or carried.

Use Cases:

• Tunnel safety systems.
• Visitor tracking in secured zones.
• Event management and access control.

Pros:

• Affordable and flexible deployment.
• Minimal hardware is required for personnel.

Cons:

• Susceptible to environmental signal variation.
• Accuracy is not suitable for fine-grained tracking.

3. Angle of Arrival (AoA)

Description: Lansitec’s AoA solution utilizes Bluetooth Low Energy and direction-finding antennas to identify the angle from which a signal is received. This enables the precise triangulation of a device’s location.

Key Features:

• Accuracy: 0.1–1 meter.
• Real-time tracking with motion trail capabilities.
• Requires fixed, synchronized anchor nodes.

Deployment:

• Strategically installed AoA gateways with antenna arrays.
• Devices emit BLE signals that receivers interpret directionally.

Use Cases:

• Real-time inventory management.
• Indoor navigation for personnel or AGVs.
• Hazardous area compliance.

Pros:

• Sub-meter accuracy.
• Detailed movement history.

Cons:

• Precision installation required.
• Medium overall cost due to infrastructure complexity.

4. Ultra-Wideband (UWB)

Description: UWB systems use ultra-short radio pulses to calculate the precise distance between tags and anchors via time-of-flight measurements. The result is highly accurate, real-time location data.

Key Features:

• Accuracy: 0.1–0.5 meters.
• Robust against multipath and RF interference.
• Requires synchronized UWB anchors and mobile trackers.

Deployment:

• Anchors installed in a 3D configuration for triangulation.
• Tags affixed to equipment, personnel, or robots.

Use Cases:

• Tool tracking in high-precision manufacturing.
• AGV and robot navigation.
• Secure access and high-value asset monitoring.

Pros:

• Best-in-class accuracy.
• Reliable in dense, complex environments.

Cons:

• High system and maintenance costs.
• Complex calibration and setup.

Selecting the Right Solution for Tracking

Choosing the right positioning solution requires balancing trade-offs:

Key Decision Factors:

• Accuracy Needs: Do you need sub-meter precision or room-level presence?
• Operational Environment: Is it an indoor, outdoor, or mixed setting? Are there obstructions?
• Scalability: Will the solution need to scale across buildings or regions?
• Power Budget: Can the devices be frequently charged, or must they last for years?
• Budget: Consider both CapEx (hardware) and OpEx (installation, maintenance).

Recommendations by Use Case:

• Warehousing & Retail: Start with B-Mobile or B-Fixed for cost-effective asset and personnel tracking.
• Healthcare & Tunnels: B-Fixed for safety compliance and real-time movement tracking.
• Manufacturing & Logistics: AoA for precise internal asset movement and flow analysis.
• Autonomous Systems & Robotics: UWB for precision-critical operations.
