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 Cell Phone Signal Strengths Should Be Measured?

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.

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.

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