Researchers developed a compact aperture-adjustable antenna that maintains strong performance across the 57–71 GHz 5G band and improves signal strength by up to 62.2% at both lower and upper-band-edge frequencies. The system achieves data transmission speeds of up to 56 Gb/s, supporting future Beyond 5G and 6G applications.
A team at the University of Kansas will develop intelligent spectrum management frameworks to enable reliable communication for drones. They aim to study how to use a proposed 5030-5091 MHz frequency band efficiently, with potential benefits including quicker deliveries and improved emergency response.
Southwest Research Institute (SwRI) has installed a private 5G network to boost security, eliminate dependency on outside mobile networks, and expand off-site capabilities for advanced 5G projects. The secure network supports various 5G advancements, including cybersecurity research, drone technology, and antenna development.
A team of scientists from Tokyo Institute of Technology has developed a wirelessly powered transmitter-receiver for 5G networks that can transmit power and signals simultaneously. The device overcomes the limitations of previous devices by generating power over large angles and distances.
Researchers developed a novel receiver scheme for detecting complex-valued double sideband signals with field recovery, called carrier-assisted differential detection (CADD). CADD doubles the electrical spectral efficiency compared to conventional carrier-less differential detection, and is insensitive to chromatic dispersion.
Dartmouth researchers create customized reflectors using 3-D printing to optimize wireless coverage, strengthening signals while making them more secure. The technology reduces interference and costs, offering improved performance and physical security for a fraction of the cost of traditional solutions.
Researchers analyzed firefly flash signals to understand how new mating signals arise through evolution. They found variations in luciferase and opsin genes didn't correlate with signal color changes, suggesting natural selection may be acting on unknown DNA sequences.
Researchers at UT Austin break reciprocity in conventional antennas, enabling independent control of incoming and outgoing signals with large efficiency. This breakthrough technology may lead to faster data rates, improved connections, and reduced bulky systems in various applications.
