Real-Time Location System (RTLS) anchors are the battle-tested, fixed radiofrequency (RF) readers that determine the precise location of tags and devices. Building a highly reliable advance tracking system requires a scalable anchor infrastructure to deliver proactive visibility and measurable ROI. By triangulating exact physical coordinates, these vendor-neutral anchors play a crucial role in eliminating operational bottlenecks, making them indispensable in industries ranging from heavy manufacturing to healthcare.
Functionality of RTLS Anchors
RTLS anchors work by detecting signals from RTLS tags and transmitting this data to a central location server.
Through advanced tracking technologies and triangulation methods, anchors calculate the real-time position of tags, providing actionable insights into asset and personnel movement.
RTLS providers have advanced filtering algorithms to determine the exact location of assets across challenging environments.
Types of RTLS Anchors
Ultra-Wideband (UWB) Anchors
- Known for their high precision, UWB anchor trackers offer location accuracy within centimeters.
- Ideal for environments requiring granular tracking, such as manufacturing and healthcare.
- Typically require PoE, however there are a few providers that offer battery powered anchors.
Bluetooth Low Energy (BLE) Anchors
- Energy-efficient and cost-effective, making them suitable for large-scale deployments.
- Often used in retail, offices, and other environments with moderate accuracy requirements.
Wi-Fi-Based Anchors
