SAR 
Specific Absorption Rate

SAR stands for Specific Absorption Rate, which is the unit of measurement for the amount of RF energy absorbed by the body when using a mobile phone.  The SAR is determined at the highest certified power level in laboratory conditions.  However, the actual SAR level of the phone while operating can be well below this value.   This is because the phone is designed to use the minimum power required to reach the network.  Therefore, the closer you are to a base station, the more likely it is that the actual SAR level will be lower.

2 G auction 2014

Auction result for 2G spectrum has been released. The government has received bids worth over Rs 60,000 crore from the telecom spectrum auction which ended on 10th day.

mobile phone radiation

According to World Health Organization there is no risk by mobile phone radiation about cancer, brain tumor or any other disease. Even, many researchers have proved it. But, it is to be found, that in their research there were some shortcomings.
So, Mobile phone is safe or unsafe. But, even if it is safe, there is no problem to use the guidelines while using a mobile phone provided by different government and regulatory authorities.

Mobile tower radiation hazards
Mobile tower radiation is more powerful compare to cell phone radiation. Therefore, it is recommended by many researchers that people should not live near to mobile tower.
We should not live near the mobile tower up to a distance 300 meters. The ragulatory agencies have given many standards for the maximum radiation. In different countries there are different standards for maximum power radiation.
In a single mobile tower there are many antennas installed for omnidirectional communication. Mostly, one mobile tower is shared by many mobile network companies to reduce the cost.

Recommendation for Using mobile phone

Examples of the recommendations are:

1.       Keep the mobile phone away from the body.

2.       Do not telephone in a car without an external antenna.

3.       Use the speakerphone instead of putting the phone to your ear.

4.       Use a wired headset to limit your exposure to the cell phone -- ideally, an air-tube headset that conducts sound but prevents any radiation from traveling up the wire to your brain.

5.       Use the phone in open spaces as often as possible.

6.       Stay still when using a cell phone. If you keep moving around with it, more radiation is emitted because the phone needs to keep track of you.

7.       Turn the cell phone off when not in use.

8.       Children’s anatomical differences may allow greater exposure of their brain regions from cell phone RF because of differences in electrical conductivity in their bone marrow.

9.       Look for products designed to shield you as a cell phone user

Ø  A cell phone EMF protective device. These are small chips or button that are adhered to the phone reducing the impact of the transmitter signals.

Ø  A screen type shield. This is a screen placed over the phone's earpiece

10.    Purchase a cell phone that rates as low as possible on the scale of radiation emissions.

11.    Avoid sleeping with your mobile phones. Figure shows the percentage of users sleeping with their mobile phones

mobile phone bad effects

The telecommunication industry is experiencing a robust growth on a global scale and the cell phones are becoming an essential tool in the global modern society as they allow people to maintain constant and continuous communication without hampering their freedom of movement. The cellular phone has to emit radio frequency energy at levels high enough to reach base stations. Though phone manufacturers, regulatory agencies and service providers assure that cell phones are safe, the global debates and controversy over the health effects of these products continue. The transmitted power from ordinary handset is absorbed in the user’s head, hand or body due to the very small distance and strong interactions. There are reports from cell studies as well as animal studies that there may be a significant risk of developing cancer tumors, foremost brain tumors in the user of cellular phones. This paper goes for a simple but elaborate study of the sensitivity of human health due to the radiation of mobile phone while using it.
