Is Verizon Interested In Clearwire?

Verizon Wireless reportedly has offered $1 billion to $1.5 billion to acquire some of Clearwire’s spectrum leases, possibly complicating Sprint Nextel’s attempt to buy out the company in conjunction with its acquisition by Softbank.

Clearwire is struggling financially but owns broad swaths of spectrum, the lifeblood of wireless networks. The April 8 bid from “Party J,” which Clearwire disclosed in a Securities and Exchange Commission filing on Friday, is the latest in a series of offers for its spectrum licenses. Unnamed people familiar with the matter identified “Party J” as Verizon Wireless, according to a report in The Wall Street Journal.

Clearwire is a key part of a complicated set of possible transactions that could make a much stronger competitor out of Sprint, the country’s third-largest mobile operator. Sprint already owns roughly half of Clearwire and is bidding about $2.2 billion to buy the rest of its stock. That deal depends on Softbank’s planned $20.1 billion offer for 70% of Sprint, which is still undergoing regulatory review.

Clearwire holds 150MHz of spectrum or more in most major markets of the U.S. Verizon would buy only a portion of that spectrum. “Party J offered to acquire Clearwire spectrum leases generally located in large markets,” Clearwire said in the Friday filing, a proxy statement to shareholders on the Sprint buyout bid. The proposed gross price of $1 billion to $1.5 billion would be reduced by what Clearwire pays for the leases, which could be substantial, according to Clearwire’s filing. The company said it would discuss the offer with “Party J” and Sprint.

6 of 10 Companies Approve BYOD

More than six out of 10 companies allow or mandate the use of employee-owned mobile devices for work in order to increase productivity, according to a survey published on Tuesday.

While the BYOD (bring your own device) push has been at the forefront of press coverage, the majority of companies still provide at least a subset of devices to employees. One third of companies strictly mandate which devices can be used for work purposes and don’t allow any type of device provided by the employee, according to the survey conducted by the Computing Technology Industry Association (CompTIA), a nonprofit trade group.

The online survey of 502 U.S. IT and business executives was conducted in February. It also found that the most popular option, at 58%, was to have a mix of corporate-owned and employee-owned devices.

For 53% of those surveyed, the top reason for allowing employees to use or select their own devices was to increase productivity while employees are away from the office. Another reason was that employees like to use familiar devices.

Twelve percent of the respondents stated it was simply too difficult to stop employees from using their own devices.

CompTIA’s report said that companies looking to maximize the benefits of a mobile device-enabled workforce must “look beyond simply which devices are used and re-examine business processes and workforce needs.”

Companies should assess the specific needs of workers, rather than just deploying one device over another on a corporate-wide basis, said Seth Robinson, director, technology analysis, at CompTIA.

TSMC Testing ARM’s Cortex A57

ARM and TSMC have manufactured the first Cortex A57 processor based on ARM’s next-gen 64-bit ARMv8 architecture.

The all new chip was fabricated on TSMC’s equally new FinFET 16nm process. The 57 is ARM’s fastest chip to date and it will go after high end tablets, and eventually it will find its place in some PCs and servers as well.

Furthermore the A57 can be coupled with frugal Cortex A53 cores in a big.LITTLE configuration. This should allow it to deliver relatively low power consumption, which is a must for tablets and smartphones. However, bear in mind that A15 cores are only now showing up in consumer products, so it might be a while before we see any devices based on the A57.

In terms of performance, ARM claims the A57 can deliver a “full laptop experience,” even when used in a smartphone connected to a screen, keyboard and mouse wirelessly. It is said to be more power efficient than the A15 and browser performance should be doubled on the A57.

It is still unclear when we’ll get to see the first A57 devices, but it seems highly unlikely that any of them will show up this year. Our best bet is mid-2014, and we are incorrigible optimists. The next big step in ARM evolution will be 20nm A15 cores with next-generation graphics, and they sound pretty exciting as well.

Blackberry Plans New Tablet

BlackBerry plans to roll out a larger tablet and two phone-tablet combos, or phablets, over the next year, according to a leaked road map presentation slide.

The three devices will run the BlackBerry 10 mobile operating system, which powers the Z10 smartphone and the upcoming Q10, which features a physical qwerty keyboard, according to the slide, which first appeared over the weekend on Twitter as @BB10Leaks.

BlackBerry officials didn’t comment on the road map. However, in comments to analysts last Thursday, CEO Thorstein Heins said repeatedly that the company will introduce more BlackBerry 10 devices this year, though he didn’t indicate what form factors the products would feature.

The three new devices shown in the slide include a BlackBerry 10 tablet with a widescreen aspect ratio, as well as a “U10″ phone-tablet, which some call a phablet, and an “R10″ phablet with a physical qwerty keyboard.

The slide indicates that the B10 tablet will ship in the third or fourth quarter, while the two phablets will be released later, with the U10 shipping at the end of the year and the R10 in spring of 2014.

There are no specifications on the slide, but the devices appear to be shown roughly in proportion to one another, with the phablets appearing to be wider than the existing Z10 and Q10 smartphones.

BlackBerry already has a 7-in. tablet called the PlayBook that is more square in shape than the widescreen look of the B10 in the slide. Some analysts and bloggers said it’s possible that BlackBerry is developing a competitor to the various 9-to-11-in. tablets already on the market, including many Android tablets, as well as the 9.7-in. iPad.

“BlackBerry wants to be a full-line competitor, particularly for business users, so they have to have a full line of products to compete head-on with Apple and Android, primarily Samsung,” said Jack Gold, an analyst at J.Gold Associates. “I would expect any viable competitor to establish a full line of products touching on all the various preferences of the marketplace, which includes smartphones, phablets and tablets.”

Gold couldn’t confirm whether any of the details in the leaked slide were accurate, but he noted that it doesn’t appear to include the mid-priced smartphones that Heins and other executives have hinted that BlackBerry may launch over the next few quarters.

The PlayBook tablet first went on sale in April 2011, running on what BlackBerry then called the BlackBerry Tablet OS, based on QNX. BlackBerry later said it would merge that tablet operating system into BlackBerry 10. The company also released a major update to the PlayBook tablet operating system in February 2012.

The first release of the PlayBook was criticized for not having native email.

Analysts are not sure that BlackBerry can keep up with production demand for so many new devices that depend on a relatively constrained supply chain for displays and other components. But to boost its global smartphone market share, currently at less than 10%, BlackBerry will need a product lineup with a variety of options.

Lenovo To Buy NEC’s Mobile Phone Unit

Japan’s NEC Corp is in negotiations to sell its struggling mobile phone unit to its PC venture partner Lenovo Group Ltd, a source familiar with the discussions said, confirming media reports of the negotiations.

NEC is also in talks with potential domestic buyers, the source said on condition that he wasn’t identified.

NEC has until now said its mobile business is an important part of its overall operations. But after two years of losses the company is shedding assets to bolster profitability.

“Amid the rapidly changing market we are considering a number of ways to bolster the competitiveness of our mobile phone business, but nothing has been decided,” NEC said in a statement through the Tokyo Stock Exchange on Friday in response to the media reports.

Lenovo officials could not be immediately reached for comment.

Japanese phone makers have struggled to gain traction overseas inmarkets dominated by Samsung Electronics Co Ltd and Apple Inc where they are also being challenged by upcoming Chinese makers. In Japan, the two foreign giants are whittling down their share of cell phone sales.

Last October, NEC cut its mobile phone sales target for the year ending March to 4.3 million from a previous estimate of 5 million units. Lenovo, the world’s No.2 maker of PCs, is cranking up overseas expansion in smartphones after solid growth in China.

Japan’s biggest cell phone maker, Sony Corp, is vying with China’s Huawei Technology Co and ZTE Corp to be No.3 in the global smartphone market.

NEC also plans to sell its mobile services subsidiary NEC Mobiling Ltd for as much as $850 million, separate sources told Reuters this month.

Marubeni Corp’s telecommunications unit and TD Mobile, a joint venture between Toyota Tsusho Corp and Denso Corp, are vying for the 51 percent stake, the sources said.

LinkedIn Beefs Up

LinkedIn has re-tooled its search engine with changes designed to make it easier for members to find information on the business networking site, whose volume of content has increased and grown more diverse in recent years.

Launched in 2003, LinkedIn initially focused on giving professionals a place to feature their resumes and career bios, as well as connect with peers and colleagues, but the site has progressively become more interactive and houses a much larger repository of data beyond individual profiles.

For example, almost 3 million companies have set up corporate pages, more than 1.5 million groups have been created, the site features a jobs section, and individuals and publishers are able to post and share comments and links to articles.

So it’s not surprising for LinkedIn to focus on improving its search engine, which fielded 5.7 billion queries last year.

LinkedIn members have until now had to run separate queries for groups, companies, jobs and other professionals, but that’s changing with the upgraded search engine.

“Now, all you need to do is type what you’re looking for into the search box and you’ll see a comprehensive page of results that pulls content from all across LinkedIn including people, jobs, groups and companies,” Johnathan Podemsky, a LinkedIn product manager, wrote in a blog post on Monday.

Users can still segment results, so as to see only job results, for example.

The LinkedIn search engine is also gaining auto-complete and suggested-searches functionalities to help people fine-tune query terms. In addition, the search engine will log members’ search queries and “learn” from them in order to deliver more relevant results.

It will also be possible for users to save search queries and be alerted about new or changed search results. The advanced search option has also gained more search filters, including location, company and school.

However, the search engine still doesn’t include content from the company’s SlideShare site, which about 60 million monthly visitors use to upload, share, rate and comment on primarily slide presentations, but also documents, videos and webinars.

Also, the search improvements are being applied to the main site, not to the mobile apps, although doing so is something the company is looking into, according to a spokeswoman.

LinkedIn started to roll out the new search features on Monday, and expects to finish delivering them to every member worldwide in the coming weeks.

As of the end of 2012, LinkedIn had topped 200 million registered members located in more than 200 countries.

Are CUDA Applications Limited?

Acceleware said at Nvidia’s GPU Technology Conference (GTC) today that most algorithms that run on GPGPUs are bound by GPU memory size.

Acceleware is partly funded by Nvidia to provide developer training for CUDA to help sell the language to those that are used to traditional C and C++ programming. The firm said that most CUDA algorithms are now limited by GPU local memory size rather than GPU computational performance.

Both AMD and Nvidia provide general purpose GPU (GPGPU) accelerator parts that provide significantly faster computational processing than traditional CPUs, however they have only between 6GB and 8GB of local memory that constrains the size of the dataset the GPU can process. While developers can push more data from system main memory, the latency cost negates the raw performance benefit of the GPU.

Kelly Goss, training program manager at Acceleware, said that “most algorithms are memory bound rather than GPU bound” and “maximising memory usage is key” to optimising GPGPU performance.

She further said that developers need to understand and take advantage of the memory hierarchy of Nvidia’s Kepler GPU and look at ways of reducing the number of memory accesses for every line of GPU computing.

The point Goss was making is that GPU computing is relatively cheap in terms of clock cycles relative to the time it takes to fetch data from local memory, let alone loading GPU memory from system main memory.

Goss, talking to a room full of developers, proceeded to outline some of the performance characteristics of the memory hierarchy in Nvidia’s Kepler GPU architecture, showing the level of detail that CUDA programmers need to pay attention to if they want to extract the full performance potential from Nvidia’s GPGPU computing architecture.

Given Goss’s observation that algorithms running on Nvidia’s GPGPUs are often constrained by local memory size rather than by the GPU itself, the firm might want to look at simplifying the tiers of memory involved and increasing the amount of GPU local memory so that CUDA software developers can process larger datasets.

Will Tegra 4 Help nVidia’s Financials?

Trefis analysts believe Nvidia’s Tegra business is likely to grow over the next few years, although Nvidia won’t become a mobile chip company anytime soon.

In a note published a couple of days ago, Trefis concluded that Nvidia has managed to offset the impact of the PC slump thanks to mobile revenue. The PC market took a massive hit in 2012, and although things are looking up, Tegra could still come in handy.

Nvidia currently earns about 18 percent of its revenue from Tegra processors, which is not bad for a product that was on the drawing board just a few years ago.

“We estimate Tegra sales to grow at a CAGR of 17% until 2016. While we believe that Nvidia will manage to expand its footprint in mobile computing, we think that the increasing competition will keep its growth rate lower than the industry average,” said Trefis.

However, Trefis went on to conclude that Nvidia had more lack with tablets than smartphones. Last year it scored several big tablet design wins, but relatively few phone wins. The Tegra 4i, with integrated LTE, should lend a helping hand, but it won’t be ready for much of 2013. In addition, Nvidia is facing more pressure from Qualcomm and Samsung, while at the same time it was forced to push back the introduction of Tegra 4 due to technical issues.

Trefis believes Tegra’s contribution to Nvidia’s overall revenue could reach over 25 percent by 2019, which means the Tegra business won’t expand much in a mature smartphone market.

Nvidia has Tegra, AMD has consoles, so both outfits have something to fall back on in a slow PC market, at least for the time being.

Is Apple Really Security Conscious?

Is Apple proving how clueless it is about security by backing a method of replacing passwords with fingerprint readers?

Just days after a scandal where a South American hospital was staffed by phantom doctors who used silicon fingers of their colleagues to convince administrators’ finger print readers that they were working, Apple has decided that they are the perfect form of security.

Word on the street is that Apple is said to be planning to introduce an iPhone that can be unlocked by the owner’s fingerprint. Speculation about Apple’s plans for fingerprint recognition began last summer when the iPhone maker bought bio-metric security firm AuthenTec for $335 million.

It is believed that the iPhone 5S will have a fingerprint chip under the Home button, to “improve security and usability.” Meanwhile in an engineering journal, two Google security experts outlined plans for an ID ring or smartphone chip that could replace online passwords, which is a lot sexier than fingerprint scanning.

3G And 4G Modems Pose Security Threats

Researchers Nikita Tarakanov and Oleg Kupreev analyzed the security of 3G/4G USB modems obtained from Russian operators for the past several months. Their findings were presented Thursday at the Black Hat Europe 2013 security conference in Amsterdam.

Most 3G/4G modems used in Russia, Europe, and probably elsewhere in the world, are made by Chinese hardware manufacturers Huawei and ZTE, and are branded with the mobile operators’ logos and trademarks, Tarakanov said. Because of this, even if the research was done primarily on Huawei modems from Russian operators, the results should be relevant in other parts of the world as well, he said.

Tarakanov said that they weren’t able to test baseband attacks against the Qualcomm chips found inside the modems because it’s illegal in Russia to operate your own GSM base station if you’re not an intelligence agency or a telecom operator. “We’ll probably have to move to another country for a few months to do it,” he said.

There’s still a lot to investigate in terms of the hardware’s security. For example, the SoC (system on a chip) used in many modems has Bluetooth capability that is disabled from the firmware, but it might be possible to enable it, the researcher said.

For now, the researchers tested the software preloaded on the modems and found multiple ways to attack it or to use it in attacks.

For one, it’s easy to make an image of the USB modem’s file system, modify it and write it on the modem again. There’s a tool available from Huawei to do modem backup and restore, but there are also free tools that support modems from other manufacturers, Tarakanov said.

Malware running on the computer could detect the model and version of the active 3G modem and could write an image with malicious customizations to it using such tools. That modem would then compromise any computer it’s used on.

The researchers also found a possible mass attack vector. Once installed on a computer, the modem application — at least the one from Huawei — checks periodically for updates from a single server, Tarakanov said. Software branded for a specific operator searchers for updates in a server directory specific to that operator.

An attacker who manages to compromise this update server, can launch mass attacks against users from many operators, Tarakanov said. Huawei 3G modems from several different Russian operators used the same server, but there might be other update servers for other countries, he said.

Research in this area is just at the beginning and there’s more to investigate, Tarakanov said. Someone has to do it because many new laptops come with 3G/4G modems directly built in and people should know if they’re a security threat.
