Wherever you go, someone has a smartphone. With recent statistics showing the total number of mobile subscriptions nearing 8 billion, the dominance of phones should come as no surprise.

 

Whether at work, at home, or at a hotel, most smartphone use takes place indoors. Unfortunately, in-building wireless coverage can vary from location to location. If you’re having problems with cell signal, it’s not necessarily your carrier’s fault.

 

It’s your environment. Or more specifically, the building in which you’re using your phone.

 

Everyone has experienced bad cell signal. We’ve even developed ways to work around it. Most people know which rooms or offices at work have decent cell coverage and which ones are the “dead zones.” Other times, we make important calls outside the door, near a window, or out in the parking lot where the cell service might be better.

 

How In-Building Wireless Works

 

Much like how your building’s wireless internet, or Wi-Fi, works, an in-building wireless system takes an existing source signal and distributes it throughout the site. Also known as IBW, in-building wireless is a comprehensive cellular solution intended to bring in the cell service to every corner of your building without having to upgrade your existing service or your phones.

 

It all starts with your cell provider. Whether you’re on Verizon, AT&T, Sprint, T-Mobile or another smaller, regional, or third-party provider, the signal from the closest cell tower has to reach every part of your building. Unfortunately, many building materials naturally reject cell signals. These materials include e-glass, dense concrete, and troublesome walls with fluffy insulation.

 

Reasons for Weak In-Building Wireless Coverage

Many times the reason for poor cell signal is the distance between your building and the nearest cell tower. There’s also the variety of natural and man-made barriers surrounding a building that can block cell signal from nearby buildings. Even electrical towers, clusters of trees and nearby mountains can be contributing factors. In an urban environment, shadowed areas from skyscrapers can create an area of low signal.
