Any other vendor is going to have to offer something pretty unique in order to unseat Qualcomm from this position. They are definitely the safe choice in this arena, so unless there is a clear advantage to another product I would expect that most will stick with the Q.
Another question is whether or not leadership in this space will translate to other design wins. Success in smartphones doesn't automatically carry over to tablets, TVs, or even watches. That is going to be far from the home court advantage that Qualcomm enjoys in smartphones.
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.
