Solutions for Getting STRONGER Cell Phone Signal Inside

Which means you literally can go from 2-3 bars of reliable 4G signal to a dead zone once you go past those doors. Most places Wilson Amplifiers have measured with good signal strength starts at -70 to - 80 dBm. This means it can potentially subtract an additional -50 dBm once it reaches inside for a signal strength of -100 dBm (1-2 bars).Īnd remember, this is assuming you have PERFECT signal outside. Let’s say you have -50 dBm signal outside (full bars) but have a building or factory lined with any or all types of metal: steel, aluminum, brass, copper, iron, etc. The closer to -120 dBm, the worse your signal.

The closer you are to -50 dBm, the better your signal. Metal by far is the worst offender with up to -50 dBm lost.Īll cell phone signal operates with -50 dBm to -120 dBm. Which Building Material is the Most Disruptive to Getting Good Signal That’s why according to the 2018 In-Building Mobile Connectivity Report, employees inside office buildings deal with up to 44 hours a year dealing with poor cell phone signal. They’re always running to the window or outside. That’s why people in the center of a building never get reliable reception with any carrier. The degraded signal makes it difficult to make a call, send & receive texts, or use the internet. But once you go inside a building, it becomes a dead zone, because cell signal now must also push through walls, interior building material and other interference. Usually when you’re outdoors in an urban area, there’s enough signal to make a call. But as it reaches miles in the distance to reach your phone, external obstructions like mountains, valleys, and tall trees and open air path loss weaken signal strength. They’re the AM/FM radio and satellite communications kind used to transmit information far distances.Ĭellular signal starts out strong from the source like a cell tower or cell site. For Commercial Why Your Cell Phone Signal Isn’t Getting Inside Your BuildingĬell phone signals are RF (radio frequency) signals.
