It also connects directly to the carrier network thus providing the best coverage especially for large complexes like stadiums and airports. It’s a system of antennas and remote nodes that improve cellular coverage inside any office building.Īctive DAS uses fiber optic cables and converts analog RF signal to digital for longer cable runs and wider coverage. Let’s look at the top options: Active DAS (Distributed Antenna System)ĭAS stands for distributed antenna system.

Whereas building material subtracts dB to signal, cellular boosters add dB to signal by amplifying or bypassing building material. With the rise of faster 4G speeds and the 5G that will rival today’s WiFi networks, IT managers and facility managers are now selecting cell phone signal boosters to improve their indoor cellular connectivity. Having a strong and reliable in-building cellular connection is equally important as a secondary system when needing to connect to the internet in case of a downed or congested. While WiFi will always be the first option for connecting to the internet indoors. 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.
