I infer from the article that the positioning will all be done by the router so the consumer will not need any new hardware on their Smartphone to reap the benefits of the precise indoor positioning. I guess then the questions will be how quickly the map programs can implement the associated indoor maps ... and what options consumers have to "opt out" of being tracked.
Several nanoseconds probably refers to the time resolution of the tracking method. 3.33ns would be about 1m, and later it's indicated that location resolution is to within a meter, so while the sentence is a bit nebulous, this seems to be the intent.
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.
