- and as we push the boundaries to produce more and more cheaply-made digital logic-driven devices and wireless gadgetry we are adding to the background noise at a fantastic rate, 10dB every few years.
Thresholds are falling, noise rising, we are going to run out of SNR real soon and no amount of diversity, eye diagrams and microvoltmeters will help.
Finally we are going to have to pay attention to shielding, EMI design, precision filters and regulatory compliance just to get the simplest thing to work in this Tempest of our own making.
Only then, maybe, the unintended emitted noise will start to fall, and the power necessary to transmit useful signals will reduce, and a virtuous circle will be created to get us to where we should have been in the first place.
Funny old world, innit?
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.
