Transcript: Today, we're going to talk about cellular amplifier basics. We will cover the various functions of a cellphone amplifier: lights, installation tips, troubleshooting tips, federal regulations and much more. With me today is one of our certified installers and he's going to walk us through it all.

Wilson Pro provides pervasive mobile connectivity by deploying the most cost effective in-building amplifier solutions on the market today. We ensure mobile access everywhere with our carrier agnostic, low impact installation smart technology and virtually maintenance-free solutions.

All of Wilson Pro’s amplifiers meet the FCC and IC requirements, and our FCC certified are accepted by all US and Canadian carriers. FCC regulation. All amplifiers are sold in a kit configuration. As such, all amplifiers come with the following components: All of our amplifiers include an indoor antenna, outdoor antenna and the minimum cable required to connect these to the amplifier.

Cable links may vary by amplifier. Expansion kits are available for two, three or four broadcast antenna configurations. As of May 1st, 2014, all amplifiers must be registered with their carriers. We have links on how to register your signal booster page to help you register your amplifiers with the various carriers.

When installing an amplifier, we suggest the following practices. Mount the amplifier in a climate controlled space with adequate ventilation. A surge protector power strip is highly recommended and required for warranty. When possible, mount the amplifier in a central location relative to the area it will be covering. This helps minimize cable length and signal loss.

We do not recommend installing amplifiers in the attic. When possible, mount the amplifier close to the donor antenna to minimize cable loss and allow for as much signal as possible into the amplifier. All Wilson Pro amplifiers are smart and include these features:

  • Automatic gain control or AGC constantly monitor and adjusts the gain of the amplifier to prevent interference to the network and provide the maximum amount of coverage inside the building.
  • Oscillation detection and shutdown. The amplifier will monitor and automatically shut down any oscillating frequencies to prevent any interference.
  • Intelligent shutdown management. Once the booster has shut down a frequency or band due to oscillation or overload, it continues to monitor that frequency or band. Once it is no longer overpowering, the amplifier will repower and turn that band or frequency back on.
  • Smart technology. Every booster is constantly monitoring and adjusting itself to maintain maximum performance. 

Your coverage will always be based on the incoming signal. For example, using the Pro 70 Plus with a good incoming signal of negative 70 dB or better, you could expect to get 35,000 square feet of coverage or more inside of the building. For an okay signal of negative 71 to negative 80 dB, you can expect 8,000 to 30,000 square feet. With a weak signal of negative 81 to 90 dB, that same booster will cover 1,500 to 7,500 square feet.

Your coverage area will also be impacted by building materials within the building. Walls can absorb and reflect the signal, weakening it as it passes through. All Wilson Pro amplifiers feature a power indicator, LED screen and navigation controls.

If the power indicator light illuminates green, all is well and the amplifier is operating properly. If it is red, the amplifier has shut down at least one frequency spectrum due to oscillation or overload. To troubleshoot red light issues, cycle through the various frequency spectrums by pressing the band select button.

The offending frequency will show either OVL or OSC. OVL indicates that the frequency is an overload mode due to the incoming signal that is too strong. Relocate or detune the donor antenna to lessen the incoming signal strength. OSC indicates that the frequency is in oscillation mode due to the broadcast and donor antennas being too close together.

Increase the separation between the antennas or shield them from one another until the issue is resolved. Once the amplifier is powered up and running, you can access the information for each band on the LCD screen. The screen will display the frequency on top and the gain level and status of the band on the bottom.

Pressing the band select button will allow you to cycle through the various band. The Pro 70 Plus even features a built-in signal meter for uplink and downlink so you can troubleshoot your system without the need for additional equipment.

  • I’ve read about cell phone boosters and thought they were low-maintenance. After reading this, I realize that while they can be useful, you can’t install one and forget it’s there. There may be times when you need to adjust it. It doesn’t seem to be a big deal though from the instructions here, just a bit of a surprise.

  • Good overview of cell phone repeaters, mobile phone boosters, and the technology—and in my case equally important, terminology involved. I can’t imagine anyone trying a diy cell phone repeater, but I guess some people are too cheap to go with a cell phone booster that’s been designed by the pros. Myself, I’ll rely on a cell phone booster that’s got people backing it up.

  • I was browsing through some of the other articles here because I saw different ways to improve your cell phone signal strength. Apparently putting these in the attic isn’t the wisest course of action. Now that I saw another article mentioning it (the one here), I’ll know how to install things better.

  • Quick and to the point. When I add a piece of equipment I don’t want to be coming back twenty times to reinstall it, tweak it, or worry about whether I’m violating some FCC code. This is a thorough description of what to expect when I put in a cell phone amplifier. This is technical writing at its finest. I wish every user guide was this user friendly.
