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

Kenya kickstarts multi-billion-dollar Konza Tech City

The Kenyan government intends to spend a reported US$14.5 billion on the creation of Konza Technology City or "Silicon Savanna," which Kenyan President Mwai Kibaki hopes will become Africa's answer to Silicon Valley. Recently underway, the ambitious venture will see the construction of a brand new city on 20 sq km (7.7 sq miles) of what is currently natural savanna, 70 km (43 miles) southeast of Nairobi.Read More

UrbanHello aims to make the home phone cool again

Many of today's telecomms users find that their conversational needs are more than satisfied by smartphones, yet most still have a home phone connected to a landline. The latter has received something of a modern make-over at the hands of UrbanHello, a new startup founded in Paris, France by Hervé Artus and Catherine Seys. The appropriately-named Home Phone has simultaneously launched at CES 2013 and on Kickstarter.Read More

Researchers promise doubled wireless spectrum efficiency

Wireless carriers love to talk about a Spectrum Crunch. Like oil, wireless spectrum is a finite resource. Companies like AT&T warn that smartphone proliferation is eventually going to leave those "wells" dry. Carriers' answers to the problem usually involve government (less regulations, and more federally-owned spectrum released). However, researchers at U.C. Riverside have another solution: make those networks more efficient.Read More

US Federal Trade Commission offers US$50K prize for blocking robocalls

In the United States, about 30 billion robocalls (pre-recorded automatically dialed solicitations) are placed each year, and similar conditions hold across much of the world. In the U.S. and many other countries, most commercial robocalls are illegal. As part of an ongoing campaign against these illegal robocalls, the U.S. Federal Trade Commission (FTC) is launching its Robocall Challenge, seeking a solution that blocks illegal robocalls on cell phones and on landlines. It is offering a US$50,000 cash prize for the best practical solution. Read More

New power amplifier design could double smartphone battery life

Cell phones have come a long way in terms of battery life, but lets be honest, there's still plenty of room for improvement. The very fact that we talk about using a phone for eight hours as being good is, well, bad. While next-gen battery technologies present one solution to the dilemma, a new breakthrough from MIT spinoff Eta Devices takes a different tack – by improving power amplifier efficiency the company hopes to double the battery life of smartphones.Read More

CORDIS plans to "beam" people to meetings

In recent years, telepresence systems have become more common. Unfortunately, most of them are little more than a videophone on top of a motorized stick. The EU Commission’s Community Research and Development Information Service (CORDIS) wants to change that, by developing a system called “beaming.” When fully developed, it should reportedly provide telepresence so real that for the operator and the people at the other end, it will be like the person is actually there.
