Innovation at the edge: IoT 2.0

The IoT market predictions are astounding. By 2025, the industrial IoT market is predicted to be ${\$}$500B [1], and there will be 27B active IoT gateways [2]. There were 4.5B Bluetooth devices shipped in 2021, and this is expected to rise to 6.4B by 2025 [3]. Finally, the potential economic value of the IoT is at least ${\$}$5.5T [4]. Although each of these predictions covers a different portion of the IoT market, they all confirm that computation and communication at the edge will become ubiquitous. The low-power IoT market saw its naissance in earnest more than 20 years ago with the launch of the first commercial Bluetooth device. Today, IoT connections are growing at an average rate of 20% per year [2] with no end in sight. The exponential rise in the demand for IoT devices necessitates significant innovation in improving wireless range, increasing performance, reducing form factor, and improving interoperability and ease of use - all within an ever-decreasing power budget.
