Not particularly impressive, considering acam of Germany's TDC-GP22 and -GPX chips, which get down to mm accuracy (sub 30 ps). And they're cheap ($20 ish). TDC is straight LIDAR; the chief advantages of UWB are noise immunity and non-line-of-sight use. Time Domain also compete here on UWB, but they are pricey ($2K per Tx/Rx).
Ever since ill-fated IEEE802.15.3a UWB fiasco, I've been fascinated with possibility of the pure impulse radio. It is glad to hear there are people still exploring this technology.
By the way isn't "IR" short for Impulse Radio could be confusing with InfraRed?
A few cm accuracy at 880 metres with UWB IR is close to 2 orders of magnitude improvement on the previous state-of-the-art. Saying it is not novel/surprising is like saying that a GHz pentium running at 70mW is not novel or surprising.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
