Exploring an unmapped cave system is a daunting enough prospect on its own, but think how risky it would be to do so on another planet such as Mars. That's why a new system is in the works, which would use "breadcrumb"-dropping rovers to do the job.

While short-range radio remote control may be fine for consumer drones, long-distance delivery drones often use cellular networks to communicate with their operators. A new mobile network system could make the latter method much more reliable.

GPS has its limitations in urban areas where signals can get noisy. Now, engineers in the Netherlands have developed “SuperGPS” – a hybrid positioning system that combines wireless and optical connections to pinpoint locations within centimeters.

As part of a fast-track program to protect military satellite communications (SATCOM), Boeing recently demonstrated its new system at White Sands, New Mexico, that can autonomously detect and counter jamming efforts at the source in real-time.

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second.

Scientists have demonstrated a technique to allow quantum computers to store more information in photons of light. The team encoded eight levels of data into photons and read it back easily, representing an exponential leap over previous systems.

It may feel like 5G only just arrived, but 6G is already on the horizon. Engineers at LG and HHI have now tripled the distance record for data transmission over 6G, reaching a new milestone for practical urban coverage.

When it comes to communicating with one another while underwater, scuba divers typically use either hand signals or writing boards … both of which have limitations. Soon, however, they could be utilizing an app on their existing smartphone.

Researchers at NIST have shown that a cloud of atoms can be used as a receiver to pick up video transmissions. The team demonstrated this “Atomic Television” by transmitting live video feed and even video games through the atoms to a monitor.

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.
