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.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
