How To Boost A Cellular Signal In A Metal Building

Signal Boosters For Metal Buildings

Metal buildings offer a challenge for cellular signals. Steel or aluminum walls are very good at blocking wireless signals. Even if you have a perfect signal outdoors, you might get little or no cellular coverage indoors.

The easiest way to improve the cell phone signal inside a metal building is to use a cellular signal booster system. These systems can boost the signal indoors for one or several cell phones. They will also improve the cell signal to a hotspot or cellular router to improve your data speeds.

The right system for metal buildings will depend on a few factors. Factors like the signal strength outdoors and the size of the area you want to cover indoors.

First - What does a Cellular Signal Booster System Consist Of?

A basic metal building signal booster system might consist of four parts:

  • Outdoor Antenna
  • Indoor Antenna
  • Signal Booster (Sometimes Called A Repeater or Amplifier)
  • Cable - Connecting Everything Together

Both antennas connect to the signal booster using coax cable. The outdoor antenna sends and receives to and from your service provider's tower. The indoor antenna does the same with your cellular phones or data devices like hotspots. The booster takes the outside signal, amplifies it, then re broadcasts it indoors. The amount of coverage area you'll get indoors depends two things. It depends on the outdoor signal strength and the components of each system. To get good coverage from any system, you'll need at least three bars of signal, outdoors. You'll want to mount the outdoor antenna where the signal is the best. This is usually on top on or near the roof of a building. If you have less than three bars of signal outdoors, a systems coverage area will be significantly reduced. Sometimes you may need more than one system to cover large areas in big buildings.

Which System?

Although each system consists of similar parts, the indoor coverage area will vary.

weBoost Home 4G

For a small building, say a few hundred square feet, a small area system like the  weBoost Home 4G will work just fine. It works well in a small workshop or garage. It will also work fine in a small area within a larger building - say around your desk or work area.

weBoost Connect 4G

weBoost Connect 4g

For a bit larger metal building, the  weBoost Connect 4G system will work better. It will cover one or two thousand square feet if you're getting at least 3 solid bars of signal outdoors. It will cover more area if your outdoor signal is better.

weBoost Connect 4G-X

For larger buildings, you might consider the  weBoost Connect 4G-X System.


For very large metal buildings (like hangers or warehouses), you might also consider the  WilsonPro line of Commercial Building Signal Booster Systems. Custom WilsonPro systems can cover pretty much any sized building.
