# FAQ

Explain how your system increase cell signal ?

The cell phone booster is a device that consists of three main components, external antenna , internal antenna and the amplifier.

The external antenna is usually mounted outside the building where the signal tend be stronger and a cable is routed from it to an amplifier that sits inside the building near a power supply. The indoor antenna or the broadcast antenna is connected to the amplifier to rebroadcast the amplified signal throughout the building.

Will this system work for my particular carrier?

All our cell phone booster systems are dual band systems, meaning they operate on both 850 mega Hz and 1900 mega Hz so it can boost cell signal for all major and minor cell phone carriers in North America including AT&T, T-Mobile, Verizon, US cellular, Straight Talk, MetroPCS, Sprint and other local providers

Will this system boost signal for aircard or datacard that is provided by the carrier for internet access ?

Yes! All our booster system increases cell phone signal and data signal for faster internet browsing on any type of phone including smart phone.

What if this system does not work for me?

No Problem, we back all your purchase with 30 day no questions asked money back Guarantee! All you have to do is contact us to get an RMA number so you can send the product back to us.

What is a dB ?

dB is short for decibel, a unit that cell phone signal strength is measured:
To illustrate this with an example:

As you can see in the image above, 2 bars on your phone = -85 dB
If you add a cell phone booster system with 55 dB, it will add that much to existing signal and bring it up to -35 dB (-85 + 55 = -35). Here is where it gets a little tricky because of the negative numbers. Math 101 states when it comes to negative numbers, less is more! -35 is better then -85 and that is how increase in signal is calculated with decibels.

Some of our kits might have higher dB compared to others in the same category but cover less area. The reason for this is easy to understand in terms of a car engine. If you take a 200 Hp engine and 500 Hp engine, they both can attain 0-60 mph in a certain time, but it takes more rpm for the 200hp engine to attain that speed in that time taken by the 500hp engine. A 67 db amplifier might not have the same broadcast radius as a 55dB gain system.

The following illustration is to show you how much dB gain is required to increase signal form almost none or 0 bar.

Expected Result
55 dB System
65 dB System
70 dB System
80 dB System

How are your kits different to other stores online?

We carefully pair our amplifiers and antennas with knowledge acquired from testing and results from the real world. When we recommend a kit for you, we stand by it and make sure you have a working solution after going through the install and efforts. We also guarantee signal raise at least 5 times from where you are at present.

Installation requires no software, no need to configure your phone or amplifier. All you need is a power supply. Our technical staff will provide you with any assistance required. All our kits come prepared with step by step instructions. The only time spent during installation is the time it takes to route the cable from outside the building to the amplifier inside. Attics, store rooms and garages are good places to house the amplifier.

Does the kit I buy from your store have all the components I need ?

Yes, all our kits include the necessary cable and hardware required to install a complete working system.

How can I test to see what signal strength I have at my location?

At the this link we have listed the steps for most phones to give you a precise signal strength number. If the number you read on your phone is -51 it means you have full 5 bars, and -110 means you have no bar.

What is the difference between Signal Booster VS AT&T Femtocell Vs Verizon Network Extender

Firstly, our signal boosters also called signal repeaters does not require WiFi signal to operate. The Femtocell and Network Extenders do require Wifi signal to enhance signal and this method requires that the Wifi signal be converted to cell phone signal and vice verse. The problem with this is, that the conversion does not happen all the time and results in dropped calls. With the cell phone booster systems, that is not an issue and it works 100% of the time.

How are your kits not the same compared to other stores online?

Our expertise with cell phone signal solution lets us pair the right components that matches the right square foot coverage. Our experts can design a custom solution specific to your building size, building material and available signal.

Do I need WiFi signal for the booster system to work ?

No WiFi signal is required unlike solutions offered by Verizon and AT&T. All you need is a power supply.

Can I get longer cable lengths then what is included in your per-configured kits??

Our per-configured kits have a specific length of cable to keep the signal loss minimum due to transmission. However, if you need to absolutely extend the length of cable, then it is recommended to add more cable after the amplification stage. The signal strength in the system is stronger after it has gone through the amplifier then before. So extending the cable after amplifier is a better option.

Are these FCC approved ?

We only sell FCC approved manufactures.
