Most IoT systems use the internet to transfer data to the cloud, either via WiFi with very limited range, or an expensive cellular data connection. Sony's ELTRES LPWA network harnesses low-power wireless technology to transfer low-bit data across a wide area, with lower power consumption, making it feasible to connect a wide range of devices.
The CXM1501GR chip transmits signals in the 920MHz band to Sony's ELTRES network, and is also equipped with GPS/GNSS sensors to obtain time and position data. Sony said it'll work in a "broad range of IoT devices, aiming to develop various services making the most of stable wireless communications over long distances and while moving at high speeds, thereby creating a new market."
In a use case document, Sony said the tech could be used to "help friends find each other at a ski hill," track wildlife, geolocate ships, follow yacht races, monitor bike rentals, while tracking numerous things like drones, rental cars and trains.
The technology appears to be limited to Japan for now, where Sony recently launched an application program for interested companies. It plans to build out the network there and do extensive testing. If it works out, it could make things much more connected than they are now, with all the good -- and bad -- that entails.
