As more internet devices run increasingly data-heavy apps, there’s a squeeze on the wireless spectrum. High-frequency terahertz waves could ease the crunch with the help of chips that control the beams.

Our 25 years of scientific review shows that communications technology isn’t harmful to our health.
The new conditions that have been heaped onto Rogers as a result of the Rogers-Shaw merger could end up benefiting Canadian consumers and the economy at large.
There are fears that escalating US-Chinese tensions could threaten the independence of African and other nonaligned nations.
If a new non-alignment is to be achieved in Africa, the foreign military bases of the US, France, and China - and the Russian military presence - must be dismantled.
Chinese tech giant Huawei is among companies adopting new strategies to challenge national security reviews.
The deployment of 5G networks depends on the compatibility of the instruments and protocols of a handful of industry players.
Hiding in plain sight, they’re subtle reminders that we’re being watched, tracked, studied.
Taiwan dominates the global market for microchips – something that Washington is well aware of.
As the wireless telecommunications companies ramp up their 5G rollouts, they are beginning to pull the plug on their 3G networks. 2022 is the end of the line for the venerable cellphone service.
The radio frequency at which 5G operates in the US is close to that of an important piece of aircraft equipment, called radio altimeters.
Airplanes use radio waves to determine how far off the ground they are. New 5G cellphone services come close to the same frequencies the airplanes use. Here’s how that can be a problem.
5G is 10 times faster than 4G, promising better wireless internet access. It’s also expected to put the Internet of Things revolution in high gear.
While it may be difficult to enact a global set of regulations on surveillance technologies, individual countries can take the lead with enhanced monitoring and stronger laws.
‘Teleoperated’ HGVs combine the efficiency of automation with the safety of human oversight.
The murky blobs visible with today’s wall-penetrating radar could soon give way to detailed images of people and things on the other side of a wall – and even measure people’s breathing and heart rate.
At least half of Australians and New Zealanders in a recent study believed in one major conspiracy theory.
New 5G technologies also boast the raw ingredients needed to beam wireless power to small devices.
Technical advances are reducing the volume of e-waste generated in the US as lighter, more compact products enter the market. But those goods can be harder to reuse and recycle.
Over the coming decade, the arrival of constellations of small satellites will reshape the space industry. It constitutes a paradigm shift, particularly in terms of data gathering and processing.
