New tech to reuse radio signals around us for IoT

We live in an age where the idea of being connected is the primary objective of the technology. When the internet came into being, it showed the world the wonders of an ecosystem what a bunch of connected computers can do. The world moved on and adopted the internet as their primary source of gathering information and entertainment. But, with the newer times, the world realised the need for letting the computers talk to each other for specific tasks where there was no need for human intervention. Therefore, the Internet of Things (IoT) came into existence for fulfilling that need. However, embedding even the basic mini computers require a hefty power source to be tagged along, which slows down the implementation of IoT in the wild.

This is where Disney Research, a network of research laboratories from the Walt Disney Group, stepped in with their novel concept meant to give a boost to the implementation of IoT devices quickly – ultra-wideband (UWB) ambient backscatter system. It may sound rocket science but works on the simple principle of borrowing unused stuff lying around. In this case, that unused stuff is wasted radio signals from TV signals and mobile communication bandwidth around us.
The concept lets the devices to communicate with each other by sending radio signals borrowed from available radio waves around the device. By borrowing other’s radio signals, the receiver devices can use less power for sending signals and more for the computational section. The receiver devices are basically sensors that can reflect back the signal through ambient radio signals.
