Long Range, Low-Infrastructure Indoor Tracking


Huntsville, AL USA – Wednesday, September 28, 2016 Q-Track Corporation recently made available a video demonstrating the long range, low-infrastructure qualities of their indoor location systems. Exploiting the company’s proprietary Near-Field Electromagnetic Ranging (NFER) indoor location technology, this low-frequency approach to indoor location works well in non-line-of-sight indoor environments, delivering average accuracy better than 40cm (16in).

The video below shows how two receivers separated 130 feet apart are capable of accurate tracking in a 170ft x 70ft office facility with multiple intervening walls.
