Wi-Fi that finds you

There's a lot of buzz around "smart home" products and the convenience of advanced automation and mobile connectivity. However, new research may soon be able to add extra emphasis on "smart" by enhancing wireless technology with greater awareness. A team at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a system that enables a single wireless access point to accurately locate users down to a tenth of a meter, without any added sensors.

World's smallest TV antenna gets the job done

Researchers have developed the world's smallest television antenna without having to compromise on reception or the conditions under which it can operate. The dual antenna created at the University of Morelos (UAEM) in Mexico receives analog TK and digital broadcast channels while measuring just 11 centimeters long, 6.5 cm wide, 6 mm thick and weighing only 12 grams (when coated, the weight reaches 80 grams).Read More

Shooting planes with lasers makes for better comms

Whether they're flying over battlefields, disaster sites or search-and-rescue operations, aircraft can prove to be a valuable "eye in the sky" for ground crews. Usually, data is transmitted from those planes using radio signals. Such signals can be jammed or intercepted, however, plus bandwidth limitations put a damper on just how much data can be sent. That's why scientists from the University of Oxford and Airbus Group Innovations are now using lasers instead.Read More

Google Fiber is heading to San Francisco

Google Fiber is continuing its scattershot approach to bringing gigabit Internet to the people. Google announced Wednesday that the company will use existing fiber optic cables to bring broadband to certain apartments and condos in San Francisco.Read More

Off-grid device keeps you connected when your network can’t

Areas devoid of wireless service, or events where too many users overload the network, could become less of a connectivity issue with the recent launch of the Beartooth. Working on a sub 1 GHz bandwidth, the device is claimed to turn your smartphone into an off-grid network that enables users to talk, text and find their friends on maps where cellular service and Wi-Fi connections are non-existent.Read More

Simplified optical receiver would cut cost of fiber-to-the-home broadband

Researchers at University College London (UCL) have successfully created a new optical receiver that they believe is simple and cheap enough to produce and install on a large scale. The new technology uses a fraction of the components of existing tech, and could provide in-home data transmission rates of up to 10 Gb/s.Read More
