Communications

AGV's ultra-lightweight Sportmodular helmet is still my all-time favorite flip-face brain bucket, and the company has backed it up with a more affordable Tourmodular lid focused on longer rides, with the option to add an integrated Cardo comms unit.

Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.

We've heard about robots that communicate with one another via wireless networks, in order to collaborate on tasks. Sometimes, however, such networks aren't an option. A new bee-inspired technique gets the bots to "dance" instead.

Radio waves don't travel well through water, which is why devices such as ROVS have to be linked to their operator via a communications cable. According to a new study, however, solar panels may soon allow for practical light-based communications.

We generally don't think of fish as being a vocal bunch – after all, anglers don't typically use "fish calls" to lure them in. According to a new study, however, approximately two-thirds of all fish species probably use sound to communicate.

It feels like Wi-Fi 6 only just got here, but of course technology marches ever forward. Wi-Fi 7 is on the horizon already, and MediaTek has now announced the first live demos of the next-gen tech, which should be much faster than what we’re used to.

During the pandemic lockdowns, the humble webcam has helped many of us feel less isolated, but can lack depth. What we need is the kind of freestanding holograms like the one in Star Wars. We're not there yet, but the M by Portl comes pretty close.

Back in July, Sony launched a neckband speaker aimed at folks using a corner of the living room or spare bedroom as a home office. Now B&O and Cisco have teamed up to supply the hybrid workforce with a wireless comms hub you put on your head.

There have never been so many missions operating on the Red Planet at one time, but even after decades of technological advancements, these sophisticated robotic explorers are still at the mercy of celestial mechanics.

There are two main versions of 5G technology, depending on what you prioritize – speed or coverage. But now, engineers at UC San Diego have found a way to get the best of both worlds, using an algorithm to bounce faster signals around obstacles.

As 5G networks become more widespread, scientists are already preparing the next generation of the communication technology. Researchers at LG and Fraunhofer-Gesellschaft have now demonstrated 6G transmission across a new distance record.

It may feel like 5G networks are only just becoming mainstream, but the next iteration, 6G, is already in the works. Samsung has now demonstrated its first prototype 6G system in an over-the-air test, using terahertz (THz) frequencies.
