I attended a keynote speech by Irwin at ICASSP 2007 in Hawaii, and I kept a very good memory of him since then. I wish him well in his retirement!
As for Qualcomm, it was indeed "rapid innovation" for commercially relevant problems in Comms that pushed it to the front.
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.
