BLE asset tracking platform features super-long battery life, improved location accuracy

Link Labs announced the release of its Xtreme Low Energy (XLETM) technology for IoT asset tracking. An innovative, patented wireless communication method, XLE extends the battery life of Bluetooth Low Energy (Bluetooth LE) tags by more than 400%, or by up to three years longer, and improves accuracy in asset location to within one meter. XLE is offered exclusively in Link Labs’ AirFinder OnSite IoT asset tracking platform, which launched in March 2021.

Bluetooth LE is a type of wireless communication technology that enables IoT devices to connect and communicate with each other. Because it transfers a very small amount of data at one time, Bluetooth LE consumes a very low level of power while increasing transmission speed and accuracy in determining an asset’s location. When used in an asset management system, these qualities can make a substantial positive impact on a company’s costs – by not having to replace batteries frequently in hundreds to thousands of IoT devices, companies can save costs on both the purchase of replacement batteries and the labor required to change batteries.

Link Labs’ XLE technology conserves even more of the battery life of an asset’s Bluetooth LE tag through phase-ranging, which also more accurately identifies an asset’s location to within one meter, or three feet. When tags and beacons communicate with one another using XLE, a phase measurement provides a precise location by triangulating the location of a tag from at least three beacons. Similar to GPS, tags in an AirFinder OnSite system measure ranges to known points to quickly and precisely calculate their own x/y/z coordinates. Using this method, XLE battery tags can last up to seven years, whereas traditional Bluetooth LE tags typically last around three years.

XLE is only available in Link Labs’ AirFinder OnSite IoT platform, which makes it possible for companies of all sizes to track thousands to millions of high-value assets in campus-based environments with a high degree of accuracy, unmatched power efficiency, and affordable cost. XLE can cover a very large area but can also be scaled down based on specific business needs or only where coverage is needed.
