In backscatter communication systems, a power-constrained wireless device piggybacks its data on ambient wireless signals instead of generating its own radio frequency . Backscatter is a method of communication in which an RFID tag without a battery (or any internal power source) receives energy from an RFID reader’s transmission and uses that same energy to send back a reply. The tag receives the energy via electromagnetic waves propagated from the reader/antenna.
In backscatter communication systems, a power-constrained wireless device piggybacks its data on ambient wireless signals instead of generating its own radio frequency (RF) waves, which would. In the past two decades, point-to-point BackCom has been widely deployed in the application of radio-frequency identification (RFID) for a passive RFID tag to report an ID to an enquiring Reader over the near field (typically several centimeters). This paper presents a 5.8-GHz RFID tag that, by exploiting the quantum tunneling effect, significantly increases the range of backscatter radio links. We present an electronically simple Tunneling RFID Tag characterized by return gains as high as 35 dB with link sensitivity as low as -81 dBm.Abstract: The interest in wearable antenna design has increased significantly due to its potential applications for humans, especially in the context of RF identification (RFID) technology. RFID transponders can wirelessly transmit identification numbers or sensor data over short distances.
This paper studies tag properties for optimized tag-to-reader backscatter communication. The latter is exploited in RF identification (RFID) systems and utilizes binary reflection coefficient change of the tag antenna-load circuit.
what is backscatter
Backscattering tags transmit passively without an on-board active radio transmitter. Almost all present-day backscatter systems, however, rely on active radio receivers. This presents a significant scalability, power and cost challenge for backscatter systems. The backscatter radio system allows passive tags to consume sufficient energy from incident RF carrier signals, generated by different sources, while reflecting back part of the carrier signals to transmit the tag’s data . We propose to leverage the deployment of LiFi networks built upon LED bulbs for pervasive RF backscatter. We experimentally demonstrate that LiFi, which passively leaks RF signals, can be exploited as a radio carrier generator for low-power RF backscatter.This work promises to enable low-powered wireless sensors and a new-generation of RFID applications. A retrodirective RF tag reflects and modulates incident radio waves back in the direction of transmission, much like a corner-reflector in optics.
