Samsung's giant satellite network could enable high-speed internet access across the globe

A highly ambitious proposal recently advanced by Samsung describes the deployment of a huge network of 4,600 near-Earth satellites that would provide internet coverage on a truly global scale. The artificial constellation would more than double the number of working satellites in orbit around our planet and lead to low-latency and (potentially) low-cost access to about 200 GB of internet traffic a month for up to five billion people, no matter their location.

Now researchers at Houston's Rice University have demonstrated how UHF frequencies can be used for so-called "super Wi-Fi" without significantly interfering with legacy TV broadcasts.

LED lightbulbs create wireless networks wherever they are installed

Various researchers have created ways to transmit wireless information from LED light fittings, to act as a form of enhancement to Wi-Fi based networks known as "Li-Fi." But now engineers at the University of Virginia (U.Va) have come up with a new twist on this theme – they claim to have created an algorithm that makes almost any device fitted with standard visible- light LEDs able to communicate with other equipment with similar LEDs. So, for example, the LED headlights in your car could communicate to the car in front of you through its LED taillights, or the LED display in your clock radio could tell the coffee maker to turn on via its indicator light.
