I was late to the party. Looks like a good presentation.
I tried measuring connectorized FR4 backplane S-parameters (your slide 13) back in the day when 1Gbps Fibre Channel was leading edge. My intent was to import the s-parameters into ADS for simulation of signal performance, specifically eye patterns. I never could get good correlation between the simulated system performance and real measured system performance.
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
