It's sad that with the political climate in Washington being what it is and the general election looming (albeit in five months) even a slam dunk issue like this one probably won't get the attention it deserves in a timely manner.
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.
