channel frequency matters also because due to the physics of electromagnetic propatation, the higher the frequency the higher the signal loss, so based on the Shanon channel capacity law, higher signal losses result in lower SNR, so higher frequencies, too, result in less throughput and less range.
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.
