New technology may double radio frequency data capacity

A team of Columbia Engineering researchers has invented a technology—full-duplex radio integrated circuits (ICs)—that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same ...

Graphene could revolutionize the Internet of Things

PFL researchers have produced a tunable, graphene-based device that could significantly increase the speed and efficiency of wireless communication systems. Their system works at very high frequencies, delivering unprecedented ...

Fine-tuned: A wholly new approach to tuning a laser's frequency

(PhysOrg.com) -- For more than 30 years, scientists have been trying to harness the power of terahertz radiation. Tucked between microwaves and infrared rays on the electromagnetic spectrum, terahertz rays can penetrate clothing, ...

UK telecoms regulator studies possibility of 5G

(Phys.org)—Minding the need for more and more mobile spectrum in a post-4G environment, Ofcom, the UK telecoms regulator, announced on Friday that it is preparing to support the release of spectrum for future mobile services, ...

New algorithm resolves Wi-Fi interference problems

To overcome the problem of interference between wireless networks, a doctoral student at EPFL has developed an algorithm that automatically selects the best frequency band according to the usage of neighboring networks. This ...
