From somebody who hasn't had physics 2 in 10 years this is a great refresher!
Minor correction after running the math:
"In contrast, a 1 GHz signal has a wavelength of 0.1 m (less than 1 foot). "
1GHz in vacuum is 0.3m = 30cm = less than 1 foot
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.
