Long-Range IoT on the Road to Success
Most engineers consider the Internet of Things (IoT) as a collection of short-range wireless technologies that connect devices to the internet for some useful purpose. And most current IoT applications seem to fall into that category. However, that mindset is changing.
Many wireless standards are limited by their range, which is problematic for a number of useful applications that require much longer paths. To overcome that hurdle, a collection of newer longer-range wireless technologies have emerged. Called low-power wide-area networks (LPWANs), these links fill the gap between traditional short-range technologies and the more costly M2M alternatives (see table). Read more…
