IoT Devices: Most Initially Fail EMI Testing
According to IEEE, the basic definition of an IoT device boils down to any object that can be assigned an IP address and has the ability to transfer data over a network. Thus, an IoT device can be just about anything. Indeed, IoT devices range from low-cost consumer gadgets like $5 Bluetooth-enabled key finders to complex highly advanced sensor grids for medical, manufacturing, transportation, and utilities. Most (but not all) IoT products involve some sort of wireless, and for many designers, the RF component can be a stumbling block, with some engineers not taking wireless and EMI testing seriously.
Ultimately, there is no one-size-fits-all definition for IoT and what it means to be an IoT designer. Even the IEEE in the white paper mentioned above says the definition is “fuzzy.” An engineer working on the Bluetooth key fob faces very different challenges from someone designing industrial-grade sensors or life-saving medical devices. Similarly, they face very different test and measurement challenges. Read more…
