Link Labs launches low-cost UWB plus XLE asset tracking
Link Labs has launched Ultra, a new asset tracking product that combines UWB with their patented Xtreme Low Energy (XLE®) technology to provide greater precision for indoor location tracking at the same low cost.
With this UWB product, Link Labs has achieved location accuracy of up to 30 centimeters, enabling indoor and on-site use cases that require a more granular precision. With this level of accuracy, manufacturing operations can effectively distinguish between boarding work stations for applications such as WIP and tool tracking.
Ultra provides the accuracy and precision of UWB without the high power consumption that drives up costs. Instead, by combining UWB with XLE®, the difference in power consumption and price from XLE® alone is negligible compared to the improved accuracy. This system also supports both UWB and XLE® tags simultaneously, allowing companies to further drop prices by using the higher accuracy tags only where they need it. Tags are as low as $1 to $3 per tag per month.
With this patented technology, Link Labs provides increased value to manufacturing and other indoor or campus-based operations — pushing boundaries to provide the greatest possible location accuracy at the lowest possible cost while maintaining customer satisfaction.
XLE® is a groundbreaking proprietary 2.4 GHz radio protocol that extends the battery life of Bluetooth Low Energy IoT tracking devices by up to three years and improves accuracy in asset location to within a meter. It has two key components: an ultra low-power communications protocol and a phase-based positioning system. The addition of UWB in Ultra boosts accuracy even further.
The phase-based positioning used in XLE is a two-way Time-of-Flight (ToF) ranging technique that measures time indirectly via phase. This technique involves a tag and beacon forming a 20ms connection to make a series of phase measurements, from which the tag can estimate the distance between it and the beacon. When range measurements to sufficient beacons are collected, the tag can use them to calculate its position.
