Researchers from Osaka University and IMRA AMERICA demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.

Osaka Metropolitan University scientists detected, for the first time, collective resonance at remarkably high and broad frequency bands. In a magnetic superstructure called a chiral spin soliton lattice (CSL), they found that resonance could occur at such frequencies with small changes in magnetic field strength. The findings suggest CSL-hosting chiral helimagnets as promising materials for future communication technologies.

A research team based in Japan may be moving toward a more controlled walk by unveiling the mechanism underlying the directional decision of each quantum step and introducing a way to potentially control the direction of movement.

A research team has developed a cup holder that wirelessly charges smart phones at the same rate as wired chargers. The charger uses magnetic resonance technology to generate and transfer energy from the cup to the electronic devices.

A mobile hotspot network will enable riders on fast-moving trains to stream HD videos without interruption while underground, thanks in part to a newly-developed mmWave wireless backhaul technology. The first commercial service using this technology will debut later this year.

Satellite success is a big step forward for the Philippines and for broader efforts to establish a microsatellite consortium across Asia.

A multilevel modulation format developed by University of Nottingham Malaysia Campus researchers shows clear advantage in achieving longer fibre-transmission distances.
