Last November, we published engineer Alex Bucknall’s essay “Taking the ‘Hard’ Out of Hardware.” We recently followed up with him to get his thoughts on the future of ‘Net-connected wireless devices and the Internet of Things (IoT).
As we enter an age of connected devices, sensors, and objects (aka the Internet of Things), we’re beginning to see a drive for lightweight systems that allow for low power, low complexity, and long-distance communication protocols. More of the world is becoming connected and not all of these embedded devices can afford high-capacity batteries or to be connected to mains power. We’ll see a collection of protocols that can provide connectivity with just a few milliwatts of power that can be delivered through means of energy harvesting such as solar power. It’ll become essential for embedded sensors to communicate from remote locations where current standards like Wi-Fi and BLE fall behind due to range constraints. Low-Power Wide Area Networks (LPWANs) will strive to fill this gap with protocols such as Sigfox, LoRa, NB-IoT, and others stepping up to the plate. The next hurdle will be the exciting big data challenge as we start to learn more about our world via the Internet of Things! — Alex Bucknall (Developer Evangelist, Sigfox, France)
