Telecommunications

An extraordinary library of original files, scripts, letters, diary entries and photographs from the early days of British television went under the hammer in London earlier this year.

Google’s parent company Alphabet has decided to ground a venture aimed at bringing internet connectivity to remote corners of the globe through stratospheric balloons, announcing today that its Project Loon will be winding down.

Researchers in China have demonstrated a quantum communication network where entangled photons are beamed between drones and ground stations, successfully maintaining their quantum link over a distance of 1 km.

A quantum internet would be much faster and more secure than the regular web – and now it may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

This year has been quite a ride for OneWeb and its globe-connecting constellation of low-Earth-orbiting broadband satellites, with Chapter 11 bankruptcy, followed by a cash injection from two major new investors. Now it's back launching satellites.

Over the past few years many of us have become accustomed to unlocking phones and computers with our fingerprints, but a prototype device from a team at Purdue could one day allow payments, passwords and photos to be sent via touch.

The current pandemic has seen an uptick in online video chats. You can use smartphones and laptops, but those who prefer quality webcams may find them out of stock. Jeff Geerling built his own using a Raspberry Pi Zero W and a HQ camera module.

An Alphabet X innovation lab project has been working on a high-speed wireless optical communications network that uses beams of light instead of cables or radio waves, and folks in Kenya will be the first to benefit from the fruits of these labors.

An internet-beaming balloon has broken a flight record, staying aloft in the stratosphere for 312 days straight. Developed and launched by Loon, the balloon circumnavigated the globe for 10 months, demonstrating the resilience of the network.

SpaceX began launching its Starlink satellites into orbit last year in a bid to eventually blanket the Earth in high-speed internet, and while the mega-constellation is far from complete, some are already tapping into the connectivity on offer.

A new internet speed record has been clocked at an incredible 178 terabits per second (Tb/s) – fast enough to download the entire Netflix library in under a second. It's achieved by modulating light in new ways before beaming it down optical fibers.

The US Department of Energy (DOE) has announced and detailed a blueprint for a national quantum internet that would be super-fast and nigh on unhackable. The document describes four priority research areas, and five major milestones on the path.
