Abstract: Throughput is a critical performance metric in backscatter communication systems. Existing approaches either suffer from limited throughput or necessitate modifications to transmitters or ...

The promise of 5G Internet of Things (IoT) networks requires more scalable and robust communication systems -- ones that deliver drastically higher data rates and lower power consumption per device.

This paper presents the principles of backscatter modulation using a frequency-modulated continuous-wave (FMCW) radar system. The focus is on comparing QPSK modulation combined with two load ...

The researchers used circuit modeling, advanced modulation techniques, and polarization diversity to design a MIMO transceiver system for BackCom applications, achieving a spectral efficiency of 2.0 ...

Researchers have found a low-cost way for backscatter radios to support high-throughput communication and 5G-speed Gb/sec data transfer using only a single transistor when previously it required ...

Researchers from Pusan National University have designed a low-power backscatter communication system that they claim achieves a high spectral efficiency and enhanced energy efficiency when compared ...

The following is excerpted from Chapter 3: Radio Basics for UHF RFID from the Book, The RF in RFID: Passive UHF RFID in Practice by Daniel M. Dobkin. Order a copy of The RF in RFID: Passive UHF RFID ...

Low cost, long range, or low power — when it comes to wireless connectivity, historically you’ve only been able to pick two. But a group at the University of Washington appears to have made a ...

Passive and semipassive RFID tags do not use a radio transmitter; instead, they use modulation of the reflected power from the tag antenna. Reflection of radio waves from an object has been a subject ...
