Wireless active feedback loop for backscattering communication

The rise of the Internet of Things (IoT) is creating new communication needs that require us to completely rethink how we design wireless interaction between potentially diverse devices, which must be increasingly environmentally friendly and agile. This article introduces a wireless communication method elegantly grounded in the principle of the RF feedback loop. Unlike traditional communication methods, this approach does not require the reader to emit any waves in the absence of a transponder. Instead, communication occurs when a self-sustaining wave spontaneously emerges as the transponder enters the reader's reading zone, forming an active feedback loop between the two devices. This novel method of transmitting RF signals creates a new paradigm in the communications field that will significantly influence modes of interaction, especially in the IoT. This method significantly decreases the emission of unnecessary RF waves and ensures complete discretion for the reader when no transponder is within range. The principle of Wireless Active Feedback Loop Communication (WAFLC) has been validated through both simulations and practical tests, showing a strong correlation between the two.
