I think there is another factor at play too. Equipment spending is heavily influenced by migration to newer technology nodes. Since fewer and fewer fabs are migrating to the more advanced nodes, due to complexity and cost, there are fewer technology migrations to drive equipment spending. Even if you argue that the fewer fabs will need to buy more equipment to cover the demand, it will at least induce more fluctuation in the spending as the process migration will be more sporatic with fewer players to even out the averages.
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.
