@krisi: In the article it is mentioned as 70% energy efficient. If you take a look at the Samsung website below, it also advertises 70% energy efficient. Now 70% wih respect to which "benchmark"?...not sure.
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.
