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.

Since many of us can no longer have face-to-face chats with family and friends, we've turned to online video meetups. Google is opening up its Meet video conferencing portal to everyone with a Google account for free.

Wi-Fi 6 is finally here. The FCC has officially adopted new rules that open up the 6 GHz band for use by regular routers and wireless devices. Basically, that means much faster Wi-Fi speeds for devices that make use of this new legroom.

Digital rights advocacy group Access Now has released its annual report revealing that governments around world are increasingly shutting down the internet, often to stifle dissent particularly during times of protest or elections.

Everything needs to be online nowadays, from vending machines to smart speakers, but that costs in terms of bulk and energy use. Now researchers have come up with a chip that gets devices connected with 5,000 times less power draw than normal.

The next generation of Wi-Fi is here, with improved capacity, better performance in crowded networks and a welcome speed boost of up to 40 percent.

A new MIT system is designed for charging batteries to power a network of sensors that would transmit data from the sea floor.

​Though most of make use of radio waves to wirelessly transfer data to and from our work mobile devices and computers, there is another way. Signify has just launched a new lighting range called Trulifi that leverages light waves to send and receive wireless data throughout the workplace.​

Web forum OGUsers, popular with individuals who seek to access other people's online accounts, has itself been hacked, exposing the details and messages of some 113,000 users.

Researchers have, for the first time, used a semiconductor laser​ to send and receive radio signals. The hybrid electronic-photonic device uses a laser to extract and transmit microwave signals, providing a data rate that may one day lead to ultra-high-speed Wi-Fi.

The SLAC National Accelerator Laboratory has developed a compact antenna that can transmit radio signals underwater, and even through solid earth. The new 4-inch (10-cm) antenna exploits the piezoelectric effect to generate Very Low Frequency (VLF) waves that normally require antennae miles long.
