The WilsonPro 70 covers up to 15,000 square feet (with a very strong signal outdoors). It is a simple and efficient solution to maintain continuous communication. The system works for all cellular-enabled devices including, cell phones, iPhone, BlackBerry, smartphones, tablets, Hotspots, MiFi devices, cellular data USB cards, cellular routers, etc.

Includes Antenna Expansion Kit

This system includes the WilsonPro Pro 70 Cellular Repeater System plus other components to give you 3 Indoor Antennas. It includes additional Coax Cable, 3-Way Splitter and Lightning Surge Protector.

Use this system to spread the signal to 3 areas within a building. Use this 3 Indoor Antenna setup when the interior walls contain metal or rock and the signal from one antenna will not penetrate interior walls. They are also used to bridge an area within a building. This system comes with all the components you need for a building system covering three areas including one outside antenna, three indoor antennas, four cables and a 3-Way Splitter.

A Better Option?

For a better option supporting 3 Indoor Antennas, we would recommend the WilsonPro Pro 70 PLUS. The Pro 70 PLUS covers a large area and has over power protection. More Pro 70 PLUS information.

Coverage Area

How Large An Indoor Area Will This Signal Booster Cover?

With a very good signal outdoors (at the outdoor antenna location), this signal booster will cover up to 15,000 sq ft indoors. The amount of indoor coverage area is dependent on the outside signal strength. The stronger the outdoor signal, the more indoor area coverage. Like all signal booster systems, this system requires the outdoor antenna to be placed in an area where there is a good consistent signal in order to get the most improved signal coverage area indoors.

Estimated Coverage Area For This System Configuration

Signal Strength Estimated Indoor Coverage Area
 -100 db (1-2 Bars)  Not Recommended
 -90 db (3-4 Bars)  5,000 sq ft
 -80 db (5 Bars)  10,000 sq ft

How To Get The Best Coverage

The key to getting the best indoor signal coverage, is getting the outdoor antenna to where the signal is best. We do not recommend using this system with less than a consistent 3 bars of signal outdoors. The stronger the outdoor signal, the larger the coverage area indoors. If your signal is 2 bars or less and fluctuates downward a lot, you will not get much coverage on the inside. In this case your phone will need to be very close to the indoor antenna to see signal improvement.

 Installation Guide



Each Signal Booster is individually tested and factory set to ensure FCC compliance. The Signal Booster cannot be adjusted without factory reprogramming or disabling the hardware. The Signal Booster will amplify, but not alter incoming and outgoing signals in order to increase coverage of authorized frequency bands only. If the Signal Booster is not in use for five minutes, it will reduce gain until a signal is detected. If a detected signal is too high in a frequency band, or if the Signal Booster detects an oscillation, the Signal Booster will automatically turn the power off on that band. For a detected oscillation the Signal Booster will automatically resume normal operation after a minimum of 1 minute. After 5 (five) such automatic restarts, any problematic bands are permanently shut off until the Signal Booster has been manually restarted by momentarily removing power from the Signal Booster. Noise power, gain, and linearity are maintained by the Signal Booster’s microprocessor.

The Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator


BEFORE USE, you MUST REGISTER THIS DEVICE with your wireless provider and have your provider’s consent. Most wireless providers consent to the use of signal boosters. Some providers may not consent to the use of this device on their network. If you are unsure, contact your provider. You MUST operate this device with approved antennas and cables as specified by the manufacturer. Antennas MUST be installed at least 20 cm (8 inches) from any person. You MUST cease operating this device immediately if requested by the FCC or a licensed wireless service provider.


E911 location information may not be provided or may be inaccurate for calls served by using this device. Please note, the four largest carriers, namely, AT&T, T-Mobile, Verizon and Sprint, and more than 90 regional carriers have given a blanket consent to all boosters meeting the new certification standards
