How To Custom Design A Cell Phone Signal Booster For A Metal Building

Why do you need a custom design?

Faraday cage is the reason your metal building is acting like kryptonite to cell phone signal.

What is a Faraday cage?

Some people dance to an electronic beat, but some people dance to a wild electric field. Enter Faraday cages for safety!  Essentially a Faraday cage is a safe and secure vault for signals to enter and exit. Signals can’t come in or get out. An EM shield is a metallic enclosure that protects against the effects of an EM field.

How To Break Into the Faraday Cage?

Drill a hole, just like you would drill into a bank vault, just like that! Only here in our case we will be steeling the signal In & Out of the vault

Design

Like any good mastermind behind a heist, in a signal heist operation planning is crucial. That planning starts at knowing your assets ahead of time and using it to your advantage. 

This involves carefully taking stock of your signal strength on site.

Signal Meter and a Notepad5 Smartphone Apps to Help You Know your Cell Signal Strength with Precision Most phones use the same standard measurement system for cell signals.

However, if you’re using a smartphone, you’ll want to know how strong your cell signal really is. Your phone may be able to tell you what kind of cell network you’re connected to (e.g., LTE, 3G), but it won’t necessarily tell you how strong the signal there is.

Signal bars are usually used as a guide to how strong the connection is. But sometimes, they can be misleading. For example, if there are 3 bars on the screen, but the actual signal is very weak, then 3 bars might mean that the signal is strong enough to display on the screen. However, when the signal is really weak, the bars won’t even appear. So, it doesn’t necessarily mean that the signal is stronger than 3 bars.

Cell phones use radio waves to communicate with each other. These signals travel through space and reach our devices. To measure these signals, we need to understand some basic concepts about radio waves. Radio waves are electromagnetic radiation, which means they are energy transmitted by oscillating electric and magnetic fields. As such, they are similar to light. But unlike visible light, radio waves cannot be seen directly. Instead, they are detected by electronic equipment called receivers. A receiver converts the incoming radio wave into an electrical current or voltage that can then be analyzed. This analysis helps us determine the strength of the radio wave. For example, if you were to place your hand over a car speaker, the sound would stop because there is no longer any

Installation

It’s easy to install a home cell phone booster. It doesn’t require any special skills to do it. To install a booster yourself, first you’ll need a ladder. Then you’ll need your smartphone and a Phillips head screwdriver. Finally, if you decide to go the do-it-yourself route, you’ll need a Phillips head screwdriver, an adjustable wrench, and a ladder.

Step 1

The hardest part is installing the outside antennas, whether a Yagi or Omni antenna. You’ll need to climb onto your roof, mount an antenna, weatherproof the equipment, and run cable into your metal building that we will be sneaking the signal into. There isn’t an established standard for measuring signal strength. Some phones may show fewer bars than others. The correct measurements require a signal meter that makes sense for a professional installers.

Step 2

The next step is to find the best way to route the LMR400 cable into the building from outside the building.  This step is building specific that only you can determine , however you will be limited to what you can do with the cable length. Our standard lengths are 50 ft, 75 ft, 100 ft and for large installations you can get 500 ft cables and terminals that you can customize for your needs. The recommendation is to keep the cable length minimal to prevent any signal loss from the cable. Our LMR400 is specified as follows:
