Signal Boosters For Metal Buildings

Having A Issue Getting A Good Cell Signal To Your Phone, Hotspot / MiFi, Data Device, Cellular Router? 

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 building 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?

Can cell phone signal go through metal?

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 Signal Booster System?

Here is some information on selecting a building signal booster system. Although each system consists of similar parts, the indoor coverage area will vary.

weBoost Home Room - Small Areas

For a small building, say a few hundred square feet, a small area system like the weBoost Home Room or weBoost ome Studio 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 Home MultiRoom

The newest weBoost Home Signal Booster System. The weBoost Home MultiRoom offers a more home decor friendly look to the indoor antenna and amplifier. It will cover up to 5,000 square feet with a very good signal outdoors but more in the 1,000 to 2,000 square feet with a medium signal outdoors. We also have a custom version of the Home MultiRoom Signal Booster System that includes an antenna mount for the outdoor antenna as well as a lightning surge protector.

WilsonPro - Large Buildings

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.

Can cell phone signal go through metal?

When it comes to building materials, metal and concrete definitely have their advantages.

Metal buildings require less repair and maintenance than comparable construction materials like wood or brick. Metal is also durable and capable of withstanding the elements—adding to its overall longevity, structural integrity, and inherent appeal.

Likewise, concrete is resistant to the effects of water, wind, and fire. Because of its ability to retain heat, concrete also offers the advantage of energy efficiency, which reduces heating and cooling costs. Coincidentally, metal and concrete also share the same distinct disadvantage—they adversely affect the transmission of cellular signal.

Walls made of steel or aluminum are notorious for blocking cellular signal. Even if a strong cell signal exists outside, you may have little or no cell coverage indoors, regardless of the network carrier you use. Additionally, the industrial-strength concrete found in most modern buildings not only blocks cellular signal but absorbs and reflects many of the radio frequency (RF) waves trying to get inside.

If you own, manage, or operate a commercial building, then may wondering how you can overcome common signal-blocking materials. Here are three ways to enhance cellular coverage inside metal and concrete buildings.

1. Minimize Interference

One of the ways to enhance cell signal inside a metal or concrete building is to reduce potential electromagnetic interference in the areas where you’re experiencing weak indoor cell signal coverage.

To minimize electromagnetic interference inside your metal or concrete building, make an effort to keep WiFi routers and other wireless devices away from the areas where cellular devices are frequently used.

2. Perform a Site Survey

The quality and reliability of an in-building cell signal depends on the strength of an outdoor cell signal. Perform a site survey to determine if you receive cell signal outside your building. A cell signal meter is the most accurate way to locate nearby cell towers and test cellular signal outside your building. Aside from professional site surveys, you can use your mobile app to scan for nearby towers.

The following apps and websites are available to help you check cell signal strength and find nearby cell towers:

  • OpenSignal, an app for both iPhones and Androids, doesn’t provide specific cell tower locations, but you can view signal maps to compare the performance of networks in your area and test the speed of your mobile or Wi-Fi connection.
  • CellMapper provides up-to-date information to find 4G towers near you and shows cell site locations for all major carriers. CellMapper also offers a free Android app that pinpoints the locations of nearby towers.
  • AntennaSearch shows all cell towers within a two-mile radius via Google Maps. It also serves as a cell reception website, so you can find out if your carrier has good or poor coverage in your area.
  • CellReception also displays nearby cell towers via Google Maps. With filtering capabilities, you can perform a carrier search and view only Verizon, AT&T, or T-Mobile cell tower locations.

These tools will help you track the quality of cell signal reception in your area and determine how it might affect your in-building coverage.

If you minimized electromagnetic interference and tested to ensure that you can receive a signal outside the building, then there is a solution. Read on and find out the best way to enhance cell signal inside a metal building.

3. Install a Cell Signal Repeater System

Does metal block cell phone signals?

Metal is the #1 cellular blocking material across all buildings in America. Aluminum, aluminum foil, lead, brass, copper, steel, iron, etc., can absorb and reflect cellular frequency waves. Average signal loss ranges from -32 dB to -50 dB, enough to make your building a dead zone.

What metal stops phone signal?

Materials such as tin, copper, silver, aluminum and others can completely block the signal.

How can I get cell phone reception in a metal building?

The easiest way to improve the cell phone signal inside a metal building is to use a building 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.

What can block cell phone signal?

Hills, mountains, bluffs, heavy vegetation, and even weather can kill your cell signal. Glass/windows. When cell phone users lose signal or drop a call inside of a building, it can seem instinctive to move near a window.
