When it comes to indoor positioning technologies, two contenders stand out: Bluetooth® Low Energy (LE) and UltraWideband (UWB). Let’s explore their key differences:
- Bluetooth® LE:
- Purpose: Designed for low energy consumption, Bluetooth® LE serves as an energy-efficient alternative to classic Bluetooth®.
- Beacons: Bluetooth® LE relies on beacons—small sensors strategically placed throughout a building. These beacons emit signals at specific intervals.
- Range: Typically covers 10 to 30 meters (up to 100 meters in some cases).
- Data Transfer Rate: Up to 2 Mbps.
- Advantages: Affordable implementation, long beacon service life (around 5 years), easy installation, scalability, and real-time positioning capabilities.
- UWB (UltraWideband):
- Range: UWB boasts an extended range, making it suitable for large facilities and comprehensive area monitoring. It can cover up to 200 meters (approximately 650 feet).
- Frequency Range: UWB signals operate across frequencies from 3.12 to 10.6 GHz.
- Accuracy: Known for its precision, UWB is ideal for scenarios where tracking an entire territory is essential.
- Advantages: Scalability, accuracy, and suitability for large spaces.
In summary, choose Bluetooth® LE if you prioritize battery life and UWB if you need broader coverage and precision. Each technology has its niche, so consider your specific requirements and infrastructure when making a decision.
