They are in a strong position when it comes to modem technology. In other areas, I'm not sure. It really depends on how you read their results--which are definitely higher than their expectations, for one.
I think many try to judge Qualcomm's performance based on that of other high-tech companies, especially those they compete against Qualcomm in mobile SoCs. However, Qualcomm's strength is really in its cellular modem technology and even if they don't win the SoC socket, they often win the modem, especially in applications using LTE. Qualcomm has a clear leadership position in modem technology and it is difficult seeing this changing anytime soon.
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.
