How to Boost Cell Signal in Metal Building

Metal buildings are cost-effective and secure, but getting strong cell phone signals outside and inside the premises may be challenging. However, metal, steel, and aluminum materials are supposedly lazy conductors to carry signals from a network; hence metal building structures usually have lower network strengths. 

The growing popularity of metal structures in the United States also dampens high network strengths, which is now a major concern.

Adding a Passive DAS signal booster is a simple and economical solution to achieve a reliable cell signal inside a metal building. This article discusses cellular signals in metal buildings and the best signal boosters for different use cases.

Working of Cell Signals in Metal Buildings

Cell phones have become a common feature in American society, with over 300 million active users. The cell phone signal operates by emitting radio frequencies whenever used. The nearest cell tower’s antenna receives this signal or radio frequency and transmits it to a switching center or the hub. The call then connects to the specific mobile phone or a telephone network, which happens in less than a nanosecond.

How Should Cell Phone Signal Strengths Should Be Measured?

Cell Phone Signal Strengths Should Be Measured in metal building
Signal Strength Measured in Metal Buildings

Cell phone signal strength is always measured in Decibel-milliwatts (or dBm), which measures the power of the wave. These are expressed in negative numbers. Your network strength is higher the closer it is to -50 dBm. 

If you want to find out your signal strength in dBm in your steel building, the first step is to go to the spot where you want to measure your signal and wait a few seconds for your mobile device to measure it using its default network measuring features on your device. As you calculate your signal, take notes to determine which areas are closest to -50 dBm. You’ll be able to calculate the average signal results.

What Can Be The Possible Reason For Poor Signal Coverage inside Metal Buildings?

Many factors can interfere with the cell signals inside metal buildings, and practically, it is impossible to address each for better coverage.

Therefore, the two most common issues that may disturb your call quality and data speed are:

Geographical Reception Barriers

Geographical factors like mountains and other barriers can cause coverage issues and make it challenging for metal building routers to receive signals. While installing your metal building structure and looking out for the zonal restrictions, check out the geographical facts for better data coverage to stay connected.

Poor Localized Coverage

Cell Towers coverage and placement also play an essential role in the overall cell signal strength. If there are very few towers in your area or the ones planned are situated far away, then you may have signal issues. 

These factors are a broader coverage and may or may not directly impact your cell strength. Before checking or rectifying these factors, it is advised to check the cell strength in your locality to know more.

Ways To Enhance Cellular Coverage Inside Metal Structures

Metal Buildings always have an issue of signal-blocking due to the materials used in constructing the same. WiFi signal usually gets bounced off or is stiffed by the metal sheets. Suppose you’re also struggling with the issue. In that case, some easy ways will help improve the weakened signal-

Minimising the Interference: 

One of the most opted ways to improve cell signals in metal buildings is to reduce the pressures from electromagnetic interference in the structures where you cannot connect well. To further reduce the poor cell signal coverage, keep the wireless internet devices like wifi routers or other things away from the cellular devices you frequently use.

Site Survey:

The reliability and quality of the cell signals inside your metal buildings also depend on the outdoor cell signals. To eliminate such issues, conduct a site survey to discover all the problems related to cell signals outside your building. 

Another reliable way to find and eliminate any weak signal issue is to install a cell signal meter. This accurately measures and tests the cellular signals from nearby towers outside your structure. Use your mobile applications to complete the test if you’re not willing to conduct any professional survey and looking for a DIY method. 

Some reliable websites that will solve your purpose are- OpenSignal, CellMapper, AntennaSearch and CellReception.

Cell Signal Repeater System

Another efficient way to improve the cell signal inside your metal buildings is to install a cell signal repeater system like WilsonPro and other options. These reduce the pressure from electromagnetic waves inside the metal building and enhance cell signals to improve call quality and data speed.

Despite all the benefits and advantages of steel building, the structure may affect your access to high network signal strengths. A cellular signal booster system is the best way to improve network signals in a metal building.

The device can provide strong indoor coverage for one or multiple cell phones by amplifying the signal from an external network booster. In addition, they can also improve the signal to a hotspot or cellular router, providing faster data speeds.

weBoost Home Multiroom Cellular Booster

The weBoost Home Multiroom is the most popular cellular booster for small and mid-sized metal buildings, and it’s easy to see why. It’s affordable, efficient, and easy to install, with antennas that won’t ruin your structural aesthetics.

It was designed to work in areas that experience very weak signal strengths. Here are the key features of the we Boost Home Multiroom:

  • Offers the best 5G connectivity network levels.

  • Up to +65 dB of gain and 21 dBm uplink, and 12 dBm downlink power.
  • Customizable accessories for maximum coverage.
  • One-time purchase fee and no Wi-Fi subscription fees are required.

What Does The Cellular Signal Booster System Consists of?

A basic signal booster system in a metal building consists of four different parts: 

  • Indoor Arena,
  • Outdoor Arena, 
  • Cable to Connect Everything, 
  • Signal Booster (Also known as Amplifier or Repeater).

The primary use of both indoor and outdoor antennas is to connect to the signal booster with a coax cable. The outdoor antenna works to receive and send from your service provider’s tower. An indoor antenna also fulfils the purpose, but an indoor antenna.

Apart from the working of antennas, overall working or the speed coverage in your area further depends on two things: 

  • Components of the systems using it, 
  • Outdoor cell signal strength.

Mount the outdoor antenna on the site where your research finds the best signal coverage to get the ideal speed transferred through coax cables, eliminating any weak signal issues. To help identify the best outdoor signal coverage, ensure it has three bars highlighted. 

The ideal placement for your outdoor antenna is either on the roof or near the top. If you do not have a good signal coverage and it shows less than three bars, your speed from indoor routers will be reduced. You need to install two systems for the overall coverage.

Does Metal Roof Contribute To Poor Signals?

Metal roofs solely do not contribute to poor connection or signal issues. However, if the problem already persists, it may amplify the same. If you think a metal roof is causing interference with your signal strength, try installing repeaters to have an affordable yet simple solution. 

If you’re confused about the metal roof type or style you must opt for, then Steel and Stud experts have answers for all your issues.
