I would suspect that the same types of techniques used in military radar to protect against jamming and other electronic countermeasures could be applied to an ultrasonic system if necessary -- at added cost of course.
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.
