Millimetre waves for the last mile

Reseachers at ETH Zurich have developed a modulator with which data transmitted via millimetre waves can be directly converted into light pulses for optical fibres. This could make covering the "last mile" up to the internet ...

Optical fibers in materials: an artificial nervous system

(Phys.org)—When placed inside a material, optical fibers act like artificial nerves, transmitting valuable information about a structure's state of fatigue and wear. A new technique developed at EPFL makes it possible to ...

Submarine cables: billions of potential seismic sensors

Scientists have for the first time shown that it is possible to detect the propagation of seismic waves on the seafloor using submarine telecommunications cables. According to their observations, this existing infrastructure ...

Trapping T-rays for better security scanners

(Phys.org) —Medical diagnostic and security scanners with higher sensitivity could result from University of Adelaide research into detecting T-rays (terahertz waves).

S.Africa behind other African states in Internet access
