Sony’s Xperia Z4 Tablet is light and has two good cameras

By putting its flagship tablet on a diet, improving cameras and battery life, Sony wants to bring back some luster to the tablet market. Unlike HTC and Samsung Electronics, Sony isn’t launching a high-end smartphone at Mobile World Congress, but is hoping to make up for that with a new flagship tablet, the Xperia Z4 Tablet. 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

Net neutrality could hamper new mobile services, Nokia CEO says

New net neutrality rules just established in the U.S. may face a cool reception here at Mobile World Congress, where carriers are prime customers. Nokia’s CEO took an early shot on Sunday night.“There are some services that simply require a different level of connectivity and a different level of service,” Rajeev Suri said at a press conference on the eve of MWC. Those include self-driving cars and remote home health care, which are too important to rely on “best-effort” networks, Suri said.He’s also worried about premium services to consumers: “You just need to be able to differentiate the quality of service for higher-paying consumers,” Suri said. Otherwise, those customers may feel discriminated against, he said.To read this article in full or to leave a comment, please click here

SanDisk pushes MicroSD to 200GB

SanDisk has managed to cram 200GB of memory into a MicroSD card.The new card is a 56 percent jump on the current highest capacity MicroSD, a 128GB card.SanDisk said it managed the higher capacity by using a proprietary design and production process that allows for more bits of memory per chip.It didn’t disclose details of the process, but the capacity of the card gives a clue as to how close it has come to the current limits of manufacturing technology.Memory chips are typically sized in powers of 2, with steps such as 16GB, 32GB, 64GB and 128GB. Keeping that patten would result in a 256GB chip, but it appears SanDisk wasn’t able to do that. Instead, it settled for 200MB.To read this article in full or to leave a comment, please click here

MediaTek wants to put its chips in Chromebooks

Most Chromebooks today are running Intel processors, but chipmaker Mediatek wants to change that as it sees an opportunity to expand its market beyond Android tablets and smartphones.MediaTek’s new high-performance mobile chip, the Helio X10, already supports Chrome OS, said Kevin Jou, vice president and chief technology officer at MediaTek, in an interview on Sunday ahead of Mobile World Congress in Barcelona. Besides powering Chromebooks, the chip is also a fit for other thin-and-light laptops and hybrid laptop-tablets, he said.Chromebooks are growing in popularity as a low-cost alternative to Windows PCs for users who do most of their computing while online. Most Chromebook applications require Internet connectivity, though more applications are moving to offline functionality as well.To read this article in full or to leave a comment, please click here

Samsung hopes better looks, more power will make the Galaxy S6 a winner

Using a mixture of metal and glass, Samsung Electronics has found its smartphone mojo again with the launch of the Galaxy S6 and the S6 edge, but the new, more premium design has a few drawbacks. After many teasers and leaks, Samsung finally launched its two new flagship smartphones on Sunday evening at Mobile World Congress in Barcelona. It’s no surprise that the vendor worked hard to drum up advance publicity, because it badly needs a hit. The biggest change with the Galaxy S6 and the S6 edge is Samsung’s choice of materials. The regular S6 trades the plastic of previous models for a metal frame and glass on the back. The edge model doesn’t have exactly the same frame, since the screen curves around both edges of the device.To read this article in full or to leave a comment, please click here

MIPS Creator CI20: Sort of a challenge to the Raspberry Pi 2 Model B

Single Board Computers are all the rage these days and for a good reason: The supporting technologies have become so sophisticated and powerful and the prices so low that off-the-shelf SBCs are great for everything from embedded systems in commercial products through supporting hobby projects to being educational tools. Perhaps the most famous of SBC is the Raspberry PI (I covered the latest version of this board, the Raspberry Pi 2 Model B, in a recent article) but that’s not the only contender in the SBC market as new ones are appearing all the time.To read this article in full or to leave a comment, please click here
