1. How do I know which model is right for my cell phone? 

There are several factors to consider when selection the right amplifier/repeater for your situation.

1. What cellular service frequency range is your building located in? The best Amplifier/Repeater systems are network frequency specific. Wilson Electronics makes amplifier / repeaters for 824-894MHz range or Nextel (806-866MHz) networks. A 1900MHz range system will be available soon. You can find out the frequency range your building is located in by contacting your cellular service provider or checking with your local cellular service dealer.
2. Signal strength outside your building
3. Inside area coverage required

2. How Much Improvement Will I Get?

With a few calculations, you can get a very good idea of the improved cellular coverage area (distance from inside antenna) within your building. We have provided the following documents to help you calculate coverage area and to help you in the purchase and installation of your Wilson Amplifier/Repeater. (Note: A new browser window will open for the links below.) Contact us if you have questions or need additional help estimating coverage area.

Step 1. Get Relative Signal Strength Reading
Put your cell phone into test mode and get a Relative Signal Strength Level (RSSL) reading outside the building. Use the pdf document "Standard Phone Test Modes " which has instructions for putting a cell phone into test mode and reading relative signal strength. If your phone is not listed in this document or you need additional help getting a RSSL reading, contact Wilson Electronics tech support for help at 866-294-6996

Step 2. Estimate Antenna / Cabling Needs
Decide on which outside (Wilson Yagi recommended) and insideantennas you will be using. Estimate where you will locate the outside antenna, amplifier/repeater (located near an AC outlet) and inside antennas. Calculate the cable lengths required to connect the outside antenna with the amplifier/repeater. Concrete or metal interior walls will block the signal transmitted by inside antennas so determine if additional inside antennas and a splitter might be required. Sheet rock and studs (wood or metal) should not effect signal much if any. Calculate the cable lengths required to connect the inside antennas (and splitters if required) to the amplifier/repeater. See antenna recommendations in the "Check List" below.

Step 3. Calculate Coverage Area
Using the formula:

Signal Strength = Amp Gain + RSSL + Cable Factor + Splitter Factor + Antenna Factor

calculate Signal Strength and use chart in the document "Finding Coverage Area For Wilson Amplifier / Repeaters" to determine approximate coverage area (distance from interior antenna.  Cable, Splitter and Antenna factors are also located in the document "Finding Coverage Area For Wilson Amplifier / Repeaters". Use this guide to determine estimated coverage area using Wilson amplifier / repeaters. It provides the formula for estimating coverage considering factors such as relative signal strength outside of building, length and type of cable, antenna type and splitters used.

3. How to install a Wilson Amplifier/Repeater?

Follow our Installation Guide for installing a Wilson Amplifier/Repeater . For more help,?Please visit Accessorygeeks' Forum or Contat Accessorygeeks.comFor more information about Wilson Amplifier/Repeater, Read Brochure
IMPORTANT NOTE: The Wilson Amplifier / Repeater is used in locations where the signal from your service provider is strong outside a building or vehicle but weak inside the building. It's used where the wireless signal is blocked by the building walls or roof. If your signal is weak outside of your building, consider a power booster or antenna that connects directly to your phone for better results
