PureView smartphone

Nokia, the mobile giant struggling to catch up with rivals, may have an ace up its sleeve. The company set the benchmark for smartphone cameras with its 808 PureView smartphone last year, which came with a 41MP camera and ran on Symbian operating system.

However, the company soon began focussing its energies on Windows Phone-powered Lumia series and Symbian was retired. Now, word on the street is that the company is working on a Lumia phone that will have a 41MP camera sensor.
Previously, there had been some speculation about an upcoming Lumia phone with 41MP camera, codenamed EOS, but the rumour mill went silent after Mobile World Congress in February. Now, MyNokiaBlog has said that a source with access to the company’s plans has said Nokia is currently testing EOS on quad-core as well as dual-core chipsets.

The model was said to be tested on Qualcomm Snapdragon 800 quad-core chip, but poor battery performance made it an unviable option. Therefore, the company is going with a dual-core processor for this phone, according to the report.

Talking about the camera, the report says that the company is using a 41MP sensor similar to the one seen in 808 PureView, but will have optical image stabilisation and variable aperture lens. The company will tweak the interface of the camera app in this phone and include Xenon as well as LED flash units. Nokia is also testing 2K and 4K recording for the device, though the report says this feature is not supported currently.

Nokia EOS is said to have an AMOLED display panel with 1280x768p resolution, though the size of the screen is not clear yet. Other features confirmed by the source include FM radio, microSD support and microHDMI port. The report also says that the phone will initially be launched only for AT&T in US, and the global launch will follow 1-3 months afterwards.

Lumia 920 is the only Windows Phone 8 smartphone to have PureView imaging technology, but features a smaller 8.7MP sensor. Nokia is also said to be working on a Windows RT tablet, which will rival the likes of Apple iPad, Google Nexus 10, Samsung Galaxy Note 10.1 and Microsoft Surface.

Wireless service

“Sprint doesn’t change overnight because of SoftBank — it’s still Sprint,” he said. “Sprint transforms overnight with Dish.”

Susan P. Crawford, a law professor at Cardozo School of Law who served as special assistant to President Obama for science, technology and innovation policy, said there were pros and cons to a merger with Dish Networks. A combination with Dish Networks would pose more of a threat to AT&T and Verizon, which account for two-thirds of American wireless subscribers, than a partnership with SoftBank, she said.

But it would also weaken T-Mobile USA, the No. 4 carrier, which has been offering cheaper phone plans to consumers, like its latest contract-free phone plans.

“Right now, we have two giants and two also-rans, and now you’re getting potentially three giants dividing up the American marketplace, with T-Mobile lagging far behind,” she said of the potential Dish-Sprint merger.

It is unclear whether a Dish takeover would change much about Sprint’s wireless service. Chetan Sharma, an independent telecom analyst who is a consultant for carriers, said that the only obvious change for consumers would be at a marketing level, not a technology level. While the bills may be consolidated, it would not be easy to share the benefits of a high-speed Internet connection at home with wireless networks that connect to a phone outside, he said.

4. Cable cutting

Although satellites are used for some Internet traffic, more than 99 percent of global Web traffic is dependent on deep-sea networks of fiber-optic cables that blanket the ocean floor like a nervous system. These are a major physical target in wars, especially at special choke-points in the system. And this is not simply a theoretical prediction, the underwater battles are well underway.As much as three-fourths of the international communications between the Middle East and Europe have been carried by two undersea cables: SeaMeWe-4 and FLAG Telecom’s FLAG Europe-Asia cable. On January 30, 2008, both of these cables were cut, severely disrupting Internet and telephone traffic from India to Egypt.
It is still not clear how the cables were cut, or by whom. And for that matter, it is not clear how many cables were cut: some news reports suggest that there were at least eight. Initial speculations proposed that the cuts came from a ship anchor, but a video analysis soon revealed there were no ships in that region from 12 hours before until 12 hours after the slice.
Those cables were only the beginning. A few days later, on February 1, 2008, an undersea FLAG Falcon cable in the Persian Gulf was cut 55 miles off the coast of Dubai. On February 3rd, a cable between the United Arab Emirates and Qatar was cut. On February 4th, the Khaleej Times reported that not only these cables, but also two more, a Persian Gulf cable near Iran, and a SeaMeWe4 cable off the coast of Malaysia.
These cuts led to widespread outages of the Internet, especially in Iran. Suspicions that this reflected underwater sabotage derived in no small part from the geographical pattern: almost all the cables were cut in Middle Eastern waters near Muslim nations. Who might have done it? No one knows. But it is known that the U.S. Navy has deployed undersea special operations for decades. In Operation Ivy Bells, for example, Navy divers appear to have swum from submarines to tap an undersea cable in the Kuril Islands.
Whatever the truth behind the incident, we see that if a government or organization wants badly enough to sabotage the telecommunications across a wide swath, it is possible. New deep-sea cables are urgently needed to protect the global economy because businesses worldwide are vulnerable to the targeting of “choke points” in underwater communications.
Whether by terrorists, governments or cyber-pirates, these weak points in the chain should be keeping us all up at night.
