Kris, the MEMS microphones market is commoditized to the hilt with low margins. The volumes have to be high enough to erase Wolfson's losses. Besides Wolfson may also have loss-leading product lines which might have been offset by the microphone sales.
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.
