the throughput vs. channel width is explained by modulation. the wider the band, the higher the data rates can be. you really need to get into the modulation theory to undrstand why wider bandwidth results in higher throughput, so look at any modulation starting with AM, FM, PSQ, QPSK, QAM, etc. for symbol rate vs. channel width concept.
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.
