Is Mobile Signal Booster with radiation?

Is Mobile Signal Booster with radiation? Is it harmful to healthy?

Answer: There are radiation, if no radiation, how can cell phone signal come? But when it is air, the health effects can be ignored.

Why not call indoor?

A: Yes, because the signal is not good.

Why is it a bad signal?

A: Yes, because the radiation is not enough.

Mobile Phone Signal Booster are generally less than 2KG weight power 25dBm (320mW) or less. Phones are generally power 33dBm (2W) or less. Cell phone signal strength in the general environment of power 10dBm (10mW) or less, the worst signal environment power of 33dBm (2W), adaptive.

The above two concepts clearly, and then remember: phone close to the head only one antenna is used. Many cable antenna amplifier is normally connected, from the people’s head at least 2 meters away.

(The following data from Android phones)

1. When the phone signal is less than-90dBm, the call will be a problem.

2. After the signal is amplified, generally less than -50dBm signal strength.

3. When you call: poor signal environments, the installation does not install the amplifier with the enjoyment of the human body radiation are as follows:
After installation: -50dBm signal radiation signal space below Hershey phone 10dBm (10mW) less radiation.
Not installed: -90dBm less space when the phone signal is poor signal radiation 33dBm (2000mW) less radiation.

(so what kind of situation small radiation?)

So the mobile signal boosters installed after a bad environment, call greatly reduced radiation.

Why do I say? ? There Androidr phone, please pick up your Android phone (the system comes with a signal test software). Click: Settings → About phone → status messages, then you will see a screen similar to the following. (By some manufacturers to turn over, and may show a different way)

Figure: -77dBm is that you are now the received signal strength.

Radiation is everywhere in the universe, the human tolerance to radiation than ordinary cell phone signal amplifier that is much greater (space after installing the strongest mobile signal booster generally not more than-50dBm).
