Nokia, DoCoMo test high-frequency mobile with an eye on 5G

Nokia Networks and Japanese carrier NTT DoCoMo are testing networks using extremely high frequencies that may someday deliver multi-gigabit speed to mobile devices. The companies’ technology trial is using 70GHz radios that today are about the size of a carry-on suitcase. Eventually, the technology will shrink down to about 5 millimeters across to fit in a mobile device. So-called millimeter-wave radios can pack a lot of data into a narrow beam, and the frequencies they’re designed to use aren’t in high demand these days. That’s why Nokia and other vendors see this technology as a key part of the future 5G mobile standard coming in 2020.To read this article in full or to leave a comment, please click here

Qualcomm puts silicon brain in flagship Snapdragon 820 chip

Qualcomm wants to help future mobile devices learn about their users, by putting cognitive computing capabilities into its next mobile microprocessor, the Snapdragon 820. The chip will provide mobile devices with some brain-like learning capabilities by incorporating features from Qualcomm’s Zeroth platform. Mobile devices built with the Snapdragon 820 will be able to learn about users over time, picking up human activity patterns and anticipating actions. Putting the machine learning features on the chip, rather than in the cloud, will make mobile devices more personal and more useful than they are today, said Derek Aberle, president of Qualcomm, in a news conference at Mobile World Congress in Barcelona on Monday.To read this article in full or to leave a comment, please click here

Will network disaggregation play in the enterprise?

Disaggregation seems to be all the rage in networking these days.HP is the latest to decouple merchant silicon-based hardware from operating system software, following Dell and Juniper. The strategy is to attract web-scale companies like Google, Facebook and Amazon who need the flexibility, choice, rapid deployment/decommissioning and cost efficiency of commodity “white box” switches capable of running a variety of software packages.To read this article in full or to leave a comment, please click here

It has a 10.1-inch, 1600 x 2560 pixel screen and is powered by Qualcomm’s octa-core Snapdragon 810 processor. The Wi-Fi version weighs 389 grams while the LTE version is slightly heavier at 393 grams, and both are 6.1 millimeters thick.+ See our full coverage of MWC 2015 +To read this article in full or to leave a comment, please click here

For a speed boost, Alcatel-Lucent says use both cell and Wi-Fi

If you have both cellular and Wi-Fi, why not use both? At Mobile World Congress, Alcatel-Lucent is demonstrating a way to do that as part of the same network. Cellular and Wi-Fi are rubbing shoulders more than ever, even if that can cause friction in some cases. It’s all part of the quest for more mobile capacity for applications like video streaming. Several ways of using them together are on show at MWC. Like other vendors, Alcatel is pursuing LTE-U, which lets an LTE network use the unlicensed spectrum that powers Wi-Fi. But the French-American company is also demonstrating a technique it calls Wi-Fi boost, where users can upload data to the Internet over cellular and download it using Wi-Fi. The company plans trials of Wi-Fi boost in the second quarter of this year and will start selling it in the second half.To read this article in full or to leave a comment, please click here

NSA authorization to collect bulk phone data extended to June 1

A U.S. secret court has extended until June 1 the controversial bulk collection of private phone records of Americans by the National Security Agency.The government said it had asked for reauthorization of the program as reform legislation, called the USA Freedom Act, was stalled in Congress. The bill would require telecommunications companies rather than the NSA to hold the bulk data, besides placing restrictions on the search terms used to retrieve the records.An added urgency for Congress to act comes from the upcoming expiry on June 1 of the relevant part of the Patriot Act that provides the legal framework for the bulk data collections. Under a so-called “sunset” clause, the provision will lapse unless it is reauthorized in some form or the other by legislation.To read this article in full or to leave a comment, please click here

How a Blu-ray disc could install malware on your computer

A pair of vulnerabilities found in hardware and software for playing Blu-ray discs might come in handy for secret snooping by the U.S. National Security Agency.Stephen Tomkinson of NCC Group, a U.K.-based security consultancy, engineered a Blu-ray disc which detects the type of player the disc is running on and then picks one of two exploits to land malware on a computer. He presented the research at the Securi-Tay conference at Abertay University in Scotland on Friday.One of the problems is in PowerDVD, an application made by Taiwanese company CyberLink for playing DVDs on Windows computers. The company’s applications are often preinstalled on computers from manufacturers including HP, Dell, Acer, Lenovo, Toshiba and ASUS, according to its website.To read this article in full or to leave a comment, please click here
