AirFinder Industrial OnSite XLE: Ultra‑Long Battery Life & Precision Asset Tracking
Technology is evolving rapidly, reshaping how we drive, listen, and manage assets. In the IoT arena, connectivity solutions like Bluetooth continuously advance, driving greater efficiency across industries.
Classic Bluetooth has given way to Bluetooth Low Energy (LE), which stays in sleep mode until a system requests a connection. This power‑saving design lets a single battery last up to five years in many applications.
When it comes to asset tracking—where frequent updates are essential—battery endurance is paramount. That’s why Link Labs pioneered Xtreme Low Energy (XLE), a next‑generation industrial Bluetooth LE that can power a single tag for up to seven years. Below, we explore how XLE powers AirFinder’s Industrial OnSite solution.
How Industrial Bluetooth LE and XLE Track Assets
Bluetooth operates in the 2.4 GHz band, a spectrum shared by Wi‑Fi, ZigBee, and other devices. To avoid interference, Bluetooth employs short‑range frequency hopping across 80 channels (each 1 MHz wide), switching up to 1,600 times per second. This rapid hopping lets devices detect and negotiate clear communication paths.

AirFinder OnSite’s Bluetooth LE beacons locate tags by proximity—calculating signal strength relative to the nearest beacon. Accuracy improves only with increased beacon density, and precision is limited to the position of the closest beacon.
AirFinder OnSite XLE, however, uses phase‑ranging to pinpoint x/y/z coordinates with meter‑level accuracy. The process works as follows:
- A Bluetooth LE asset tag transmits a signal to all reachable beacons.
- Each beacon responds with matched tones or frequencies, focusing on phase differences rather than round‑trip time.
- Collected phase data allows the system to calculate distance from each beacon’s known location.
- With data from at least three beacons, the system triangulates the tag’s precise position.
- Location information is streamed in real time to the AirFinder IoT platform for immediate analysis.
Benefits of AirFinder XLE
XLE’s sub‑meter accuracy sets it apart from proximity‑based systems, which are confined to beacon locations. Additional advantages include:
- Wall‑powered beacons eliminate battery replacement costs.
- Tags enjoy extended battery life—up to 5–7 years—minimizing maintenance.
- Enhanced location precision for critical asset management.
- Coverage of larger areas with fewer beacons, reducing infrastructure complexity.
