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 ...
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 ...
Researchers from Pusan National University in South Korea recently published research into a backscatter technique they argued could prove key to enabling IoT offerings spanning smart cities, industry ...
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 ...
How a battery-free, untethered underwater camera gets its operating power via wave-energy harvesting. How the camera captures images with minimal power use. How the camera communicates captured image ...
Wireless communication systems enable the transmission of information without physical conductors by converting digital data into electromagnetic waves and propagating them through air or space. At ...
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 ...
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.
