Telcos to terminate 3G roaming agreements at Govt.'s order

The termination of 3G roaming agreements had earlier compelled telcos like Vodafone, Idea and Airtel to send a joint letter to Kapil Sibal and further on to the PM stating that termination of 3G pacts is a breach of contract and government should refund the spectrum auction payments with interest. The future of such 3G roaming was already uncertain. The final verdict is probably out and government has asked telcos to terminate 3G roaming agreements, according to TheMobileIndian. Simply put, their customers cannot use 3G services in circles, where the service provider does not have permit for 3G services. Telecom secretary R Chandrasekhar revealed, "The decision has been taken that this (3G roaming pacts) is in violation of terms and conditions of the licence. The government will be issuing notices asking operators to stop their service with immediate effect. But on penalty, no decision has been taken yet." Not being able to access 3G services, because their service provider doesn't have the necessary permissions will cause a lot of inconvenience to the users. Aircel and Tata DoCoMo, reportedly have already discontinued their pact.

Govt. norms to keep radiation from mobiles in check

India is currently home to millions of mobile subscribers. While this may seem to be a significant milestone to most, it is also an indicator of the fact that millions of us lie exposed to harmful radiation emitted by mobile phones. Numerous reports have been proof enough to convince us that total dependence on them can be fatal, to say the least. The government, however, has been constantly working out ways to ensure that radiation levels emitted by mobile phones remain under check, at all times. Times of India confirms that the government is close to enforcing a set of norms, which should meet the purpose. Hands-free, till now may have been just another accessory bundled up with a mobile phone, but soon, they will be mandatory with all mobile phones. Reason? Using hands-free, as opposed to answering calls the usual way is as an effective method of steering clear of radiation emissions. That or, switching over to SMSes as your mode of communication, altogether is preferable, too, since this way one can evade radiation. However, keeping safety tips aside, the government also plans to tighten the noose around norms, which specify the levels of radiation in every handset. Reportedly, the SAR levels (Specific Absorption Rate), i.e. the rate at which a normal human body absorbs radio frequency (RF), is currently at 2 watts/kg in India. Now, the government aims to crunch this number down further to 1.6 watts/kg average over a six minute period. These levels are decided on in compliance with the norms of the International Commission on Non-Ionizing Radiation Protection Association (ICNIRP).

Chrome beats Firefox to become second most used browser

Internet Explorer has managed to stay at the number one spot, but its market share is quickly dwindling as Firefox and Chrome compete for the next best - number two spot. A report by StatCounter, a service that monitors internet statistics has seen Chrome beat Firefox in the month of November. Chrome reportedly has a market share of 25.69 percent, as compared to Firefox's 25.23 percent through the month. Microsoft's Internet Explorer still has a healthy lead of 40.63 percent, which is slowly, but steadily dropping. Internet Explorer was the most dominant browser for a very long time. StatCounter expects Google to take on Microsoft for the number one browser place in the near future. The service records the number of users per browser and not the number of downloads that each one has. Internet Explorer continues to have a healthy market share in the U.S. In fact, the numbers in the U.S increased slightly from 50.24 percent last year to 50.66 percent this year. While Chrome might have taken a minor lead over Firefox, the trend for the newest of the browsers is healthy. It shows that Chrome will be able to extend that lead as months go by. Mozilla has made changes to make their browser more efficient, but they seem to have lost the momentum they once had with Firefox. Increasing extensions support for the Google Chrome has also been another reason for users to switch over from Firefox.

Exynos 5250, Samsung's dual-core, 2GHz Mobile Chip

Samsung announced it has started shipping test units of its latest dual-core mobile chip based on ARM's new Cortex-A15 processor design, which could boost the performance of applications and graphics on smartphones and tablets. The dual-core Exynos 5250 for mobile devices runs at a clock speed of 2GHz, providing roughly double the CPU performance of the ARM Cortex-A9 dual-core processor running at 1.5GHz, Samsung said. Compared to the latest ARM Cortex-A9 processors used in smartphones and tablets, Samsung said. The chip's 3D graphics processing capabilities are four times better, while cutting power consumption compared to current mobile chips. The chip can play back video at deeper resolutions on 2560-by-1600 pixel displays. The chip employs specific technology to make screen refresh rates more efficient when reading e-books or Web pages, which helps save power, the company said. The chip is scheduled for mass production in the second quarter of 2012. Samsung is one of the first companies to publicly announce a chip with Cortex-A15 processors, which were announced in September as a Cortex-A9 successor. ARM processors are used in most smartphones and tablets today, including the Apple iPhone and iPad. ARM, which licenses chip designs, expects Cortex-A15 smartphones and tablets to hit the market by the end of this year or early next year, initially with dual-core parts and later with quad-core parts. The Cortex-A15, which is also targeted at PCs and servers, is capable of running at up to 2.5GHz and can stretch to 16 cores in some configurations. Samsung will contend with competitors including Texas Instruments, which has said it would release OMAP 5000-series chips based on Cortex-A15, and a host of mobile chip makers including Nvidia that have licensed Cortex-A15.
