5. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna. READ MORE
