An effective IoT system needs more than low-powered IoT devices to do its job—it also needs a robust, secure and reliable network to relay and process data.
An IoT network is larger than its devices; it also incorporates the gateways that corral and route data and the systems that relay and process data. Exactly where the data is processed—in the cloud or at the edge—depends on the application, but this is the broad playing field in which IoT devices work. A low-power wide-area network is an ideal setup to support IoT sensors that cover large geographical distances and demand low power performance.
IoT networks also need the capacity to relay large volumes of data. 5G networks could be uniquely suited here as they offer the speed and capacity needed to reliably relay the sensor information that many IoT applications, including autonomous driving and robot-assisted surgeries, need to function. Network security is also a major concern, especially because IoT devices can be an easy entry point for cyber attackers.
The future of IoT looks promising, and the barriers to its adoption are, on a large scale, being eliminated. With sensor longevity and wide-area network technology starting to work together, the promise of revolutionary IoT applications are now that much closer to being realized.
