Wireless connectivity has become ubiquitous. As consumers, we have a sound appreciation of the battery life of our favorite connected tech, with some of the wearable gadgets requiring daily charging. Connectivity is the essential ingredient in the rise of the internet of things and its industrial twin, IIoT, placing much reliance on low-power wireless communication, especially for battery-powered devices. As microcontroller and wireless vendors continue to optimize their devices to consume even less power, the number of potential IoT/IIoT use cases grows further.
