Packing List of 2G 3G 4G Cell Phone Signal Booster WT-GD03: 


Installation Approaches of 2G 3G 4G Cell Phone Signal Booster:

1) The outside antenna receives the signal from the nearest mobile base station.

2) The outside antenna sends the received signal through the coax cable to the installed Repeater.

3) The repeater accepts the low signal and improves it.

4) The improved signal goes to the inside antenna through the connection coax cable.

5) The inside antenna send the improved good signal to your mobile phone.

How to Tell If a Signal Booster Will Work For You

As we know, a home cell phone signal booster needs a small amount of outside signal in the location where you mount the external antenna in order to operate properly, so you'll need to determine whether you have enough signal available.

In order to get the most accurate type of reading, we recommend putting your phone into field test mode, which is a numerical representation of the actual strength of your cell signal, rather than the dots or bars that you usually see on your phone. Once you're in field test mode and you're seeing the signal for your carrier's 3G network, then you're ready to go outside and take some actual signal readings.

The ideal place to take cell phone signal readings that is on the roof of your house where you plan to mount the external antenna. If you're able to climb up on the roof (please be safe), then you'll want to walk around the perimeter of the roof and record signal readings in as many locations as possible. You're looking for the best signal, which is the lowest decibel number or the most dots/bars, that you can find, as that will result in the most coverage from the signal booster that you purchase.

If you're not able to climb on top of the roof, then the next best option is to walk around the outside of your home with your phone, and take signal readings at ground level. You can usually assume that the signal strength you'll be getting on the roof is going to be as good or better than what you receive on the ground.

Once you know your outside signal strength, then the next step is to select the right cell phone booster for your home.


Q: How does the 2G 3G 4G Cell Phone Signal Booster work?

A: When you make a phone call or send a text message from your mobile phone, that information is transmitted as a GSM signal. Signal boosters are comprised to three main components: an outdoor antenna, an signal booster and an indoor antenna. The outdoor antenna receives the text message or call and then transmits it to the internal booster. The booster then enhances the strength of the signal(based on frequency) and then re-transmits a stronger signal through an indoor antenna to the user’s device. The outcome of using a signal booster is that voice calls will be clearer and louder, and text messages will be sent and received faster.

Q: Are your 2G 3G 4G Cell Phone Signal Booster certified?

A: Yes, all our signal repeaters are certified with CE certification.

Q: Are your 2G 3G 4G Cell Phone Signal Booster safe?

A: In fact, mobile signal repeaters and boosters typically emit considerably less radiation than a cell phone. In fact, the energy from a cell phone booster is many thousands time less than the limits for safe exposure set by the US Federal Communications Commission (FCC) and other regulatory agencies.

To further emphasize how little radiation cell boosters emit, a typical mobile phone uses 500mW – 1000mW of power and many repeaters use as little as 10mW of power. Even more, radiation emissions from cell boosters diminishes significantly as you move away from it. Even at as little as a one meter distance from the booster, radiation readings can be up to 30% lower than they are on the booster itself.

Q: How much radiation does a 2G 3G 4G Cell Phone Signal Booster emit?

A: Emissive power of a cell phone booster is typically less than 1 watt. Cell phone boosters can actually reduce the amount of radiation emitted by your cell phone. When a cell phone has weak signal, your cell phone will use more energy seeking a strong signal, causing it to output more radiation than it does with good signal strength.

The International Agency for Research on Cancer has classified RF radiation from things like cell phones, cell boosters, and Wi-Fi as class 2B possible carcinogens. While this may sound serious, and potentially unsafe, other items that fall into that category include coffee, pickled vegetables, and styrofoam cups.
