I think that reports of the death of copper are greatly exaggerated. As an engineer working to validate 10GBase-KR backplane channels running over 30 inches of copper PCB laminate and two board to backplane connectors, I am writing to report that copper backplanes are still alive and well in 2010. This copper versus optical debate reminds me a bit of the semiconductor's optical lithography versus e-beam lithography debate. Design engineers have this habit of overcoming one obstacle after another and continuing to squeeze more performance out of systems than anyone expected. The IEEE 802.3ba committee and the OIF-CEI-25 committees both working on 25Gbps copper channels haven't thrown in their towels yet either.
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.
