Plug pulled on the world's last commercial electric telegraph system

After linking the world for 167 years, the commercial electric telegraph is no more. The speed with which electromagnetic telegraph systems took over both short- and long-distance communication in the mid 19th century set the pattern which telephones and the internet would follow, spawning the connected world we now live in. The closing down of India's state-run Bharat Sanchar Nigam, Ltd. (BSNL) network on Monday sparked a last-minute rush of people looking to send a souvenir telegram to mark the historic event before the electric telegraph was relegated to the history books.

Google floats balloon-powered internet network with Project Loon

Almost two-thirds of the world still does not have access to high-speed internet, but Google is determined to change that. Unfortunately, setting up an affordable infrastructure in remote areas is beyond even a huge multinational corporation's capabilities, which is why the company had to devise a completely out-of-the-box solution called Project Loon. As part of the project, Google recently launched a series of internet-enabled balloons into the stratosphere over New Zealand to provide broadband connectivity to rural areas. Read More

Big Brother is here, and his name is PRISM

If there was any doubt that George Orwell's Nineteen Eighty-Four was a prophetic piece of fiction, you can pretty much put that to rest. The more skeptical among us have claimed for years that, in the age of the internet, nobody has real privacy. During the last 24 hours, those fears emerged from the shadows. Details leaked of the secret US National Security Agency (NSA) program called PRISM, which may as well have been called Big Brother.Read More

Sports broadcasts could soon feature Matrix-style replays

Along with its nihilistic cyberpunk style, the film The Matrix is famous for popularizing what’s known as “bullet time” photography. You know the shots where someone would run and jump, then they’d freeze and the camera would appear to track around them as they were frozen in mid-air? That’s bullet-time. Now, that same technology may be coming to live televised sporting events. Read More

Record 40 Gbit/s wireless data transmission rate matches it with optical fiber

If you thought 5G wireless was fast at one Gbit/s, how does 40 Gbit/s sound? That's the new wireless data transmission record set by a team of engineers in Germany using integrated solid state mm-wave transceivers. This data transmission rate was demonstrated over a distance of 1 km (0.6 miles) and it is hoped that such links could be used to close gaps between optical networks in rural areas at a fraction of the cost of installing optical fiber.Read More

Samsung 5G development "several hundred times faster" than LTE

LTE may only be wiping its feet on the proverbial doormat, and yet Samsung has already announced a significant breakthrough in the development of 5G mobile communications. The company says this will pave the way for next-generation mobile networks offering transmission speeds in the tens of gigabits per second, hundreds of times faster than LTE.Read More

Quantum key air to ground transmission could be future of cryptography

For the first time, quantum cryptographers have successfully transmitted a quantum key from a fast-moving object – a Dornier 228 turboprop. The experiment involved sending a secure message from the aircraft to a ground station via laser beam, and can be considered a significant step toward the creation of a network of “unbreakable” satellite data transmissions.Read More

Closing the gap to improve the capacity of existing fiber optic networks

A team of researchers working through Australia’s Centre for Ultrahigh Bandwidth Devices for Optical Systems (CUDOS) has developed data encoding technology that increases the efficiency of existing fiber optic cable networks. The researchers claim their invention increases the data capacity of optical networks to the point that all of the world’s internet traffic could be transmitted via a single fiber.Read More
