Ultracompact photodetector for optical data transmission

Data traffic is growing worldwide. Glass-fiber cables transmit information over long distances at the speed of light. Once they have reached their destination, however, these optical signals have to be converted into electrical ...

Faster prediction of wireless downtime

As the number of mobile devices grows along with demand for faster connections and larger data volumes, wireless networks can easily exceed capacity, resulting in severe network slowdowns and outages. While engineers have ...

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 ...

A yacht that pilots itself

Driverless technology is making inroads in maritime shipping, search-and-rescue operations and security work. But it has been conspicuously absent from recreational boating.

Many antennas, multiple benefits

A concept that balances large-scale installations of low-cost and low-power antennas to boost cellular coverage in difficult environments will also provide better connectivity to more users. Developed by A*STAR, this new ...
