Insufficient Towers Linked to Poor Mobile Services: Trai

The lack of adequate number of mobile towers was one of the reasons for deteriorating quality of mobile services, officials of the Telecom Regulatory Authority of India (Trai) said in Kolkata on Monday.

"Lack of adequate number of mobile towers is one of the reasons for deteriorating quality of mobile services," said Agneshwar Sen, advisor for Trai.

Sen said the guidelines for EMF radiations from BTS (base transceiver station) and mobile handsets in India were very stringent compared to other countries, including benchmarked standards of developed nations.

Allaying fears of the public, Suresh Kumar Gupta, principal advisor for Trai, stressed that the Indian government through Trai and the telecom department has put in place and "implemented stringent emission norms that ensure no adverse effects on human health from mobile tower emissions".

"Mobile tower radiations are nothing more than radio waves whose energy and frequency levels were far too low or weak in strength to present any risk or hazard to health," Gupta said at an interactive session on EMF radiation on human health.

The officials informed that various international organisations, including the WHO, have stated, in no uncertain terms, that there was "no convincing evidence linking EMF exposures with health effects in adults or children".

Explained: Camera Improvements in the New HTC 10

With the HTC 10, the Taiwanese company is promising to undo the past wrongs in the cameras of its previous flagship phones. The camera has long a weak point in HTC devices. At first, HTC sacrificed image resolution in the M8 and made the size of individual pixels larger to capture more light (what HTC called Ultrapixel). But the resulting 4 megapixel images were often fuzzy, especially when cropped or enlarged. To fix the issue, in its next flagship - the M9 - HTC went with smaller individual pixels in a 20-megapixel camera last year, but it still underperformed in extreme situations, such as indoors and close-ups. In the HTC 10, the company attempts to strike a balance with larger individual pixels (1.55µm), but not as large as before and a 12 megapixel sensor in its camera coupled with a ƒ/1.8 lens. HTC accepts that in the imaging performance in the M9 was not up to the kind of spec of what they really like to see in a flagship. HTC is giving a slight boost to the selfi...

Flexible Camera Developed That Can Be Wrapped Around Objects

A team led by an Indian-origin professor at Columbia University has created a novel sheet camera that can be wrapped around everyday objects to capture images that cannot be taken with one or more conventional cameras. "Cameras today capture the world from essentially a single point in space. While the camera industry has made remarkable progress in shrinking the camera to a tiny device with ever increasing imaging quality, we are exploring a radically different approach to imaging," said Shree K Nayar, computer science professor at Columbia University. "We believe there are numerous applications for cameras that are large in format but very thin and highly flexible," added Nayar who graduated from the Birla Institute of Technology, Ranchi, in 1984. Nayar's team designed and fabricated a flexible lens array that adapts its optical properties when the sheet camera is bent. This optical adaptation enables the device to produce high quality images over a wide ...

Samsung Galaxy J1 (2016) Leaked in Press Images

The anticipated successor to the popular Samsung Galaxy J1, tipped to be called the Galaxy J1 (2016), has once again been leaked in images on the Web. While in the previous leaks we have seen the unannounced smartphone in its Black colour variant, the new leaked image shows the handset in two additional colour variants. The image tweeted by @evleaks on Monday shows the Samsung Galaxy J1 (2016) smartphone in Gold and White colour variants. The design of the handset also fall in line with the models leaked in images previously. It is worth mentioning that the screen bezel seen in the image stay black in all the three colour variants. The smartphone is seen featuring a physical home button, along with a multi-window, and a back capacitive button on either side. At the back, the smartphone sports a camera at the centre with a LED flash and a speaker on either sides. Samsung is yet to announce the smartphone. The Samsung Galaxy J1 (2016)leaked in images last month as well...
