Knowing Where – Anywhere with Near-Field Electromagnetic Ranging
GPS provides a near-pervasive location capability outdoors. However, GPS works worst where it is needed most - in the indoor environments where we spend most of our time. A variety of technologies try to address the problem of indoor location. This talk focuses on an emerging approach: Near-Field Electromagnetic Ranging (NFERR) Real-Time Location Systems (RTLS).
Near-field wireless delivers robust short-range links due to superior propagation characteristics. NFERR RTLS uses low frequency (~1MHz) long wavelength (~300m) signals to deliver 30cm-1m accurate location at ranges of 20-60m. NFERR RTLS enables Dosimulation Systems that train nuclear workers how to minimize radiation dose. Other applications include proximity detection and collision avoidance systems to keep workers safe from their robotic co-workers, and systems that track athletes' performance. NFERR RTLS can provide location data to power a host of process control and work-flow analysis applications. This talk will discuss not only the physics and technology behind NFERR RTLS, but also existing and potential future applications.
