What Building Materials Will Affect My AT&T Signal?
Most cell phone use is indoors. Because of this we often struggle with dropped calls, bad voice quality and slow internet. While some of this is because of AT&T’s network coverage, another major factor is your home & building. Specifically, your building material.
Cell tower distance and objects like trees, mountains, and tall structures all affect your cell service. Let's explore the top culprits:
- Metal: Metal is the #1 disrupter of cellular signal. Aluminum, brass, copper, steel, iron, tin, etc. all affect signal. Any type of metal is capable of messing with your cell service.
- Low-E- Glass: Green-rated buildings are great at saving energy but are also great at blocking out cell signals.
- Brick/Concrete: Brick and concrete are robust materials that weaken or block service as it passes through.
- Plaster /Drywall: Although it doesn’t completely shut out service, it does weaken it as it passes through.
- Wood: Depending on the thickness of the wood, it’s capable of absorbing cell signal.
- Thick Walls: Thick walls hamper cellular reception, especially as it tries to reach the center of the building.
- Electromagnetic Interference: Any machine or device emits electric signals that could disrupt cell service.
What Frequency Bands does AT&T Use?
These are the known major frequency bands AT&T uses across the nation. Local & state-wide frequency bands will be updated as they come out.
| NETWORK | BANDS | FREQUENCIES |
|---|---|---|
| 5G | n5, n77, n260 | 850MHz (low), 3.7GHz (mid), 39GHz (mmW) |
| 4G | 2, 4, 5, 12, 14, 17, 29, 30, 66 | 1900, 1700/2100, 850, 700, 2300 |
How Do I Find My Nearest AT&T Cell Phone Signal Strength & Cell Tower Location?
There are a few ways to read your cell phone signal strength. How many bars you have is a good way to judge your signal, but it isn't always truthful. This is because different carriers use signal bars in different ways. The best way to check your signal is by looking at the dBm. Cell phone signal is measured in dBm, -50 dBm is great signal (full bars) and -120 dBm is poor signal.
Try these methods to check your phone’s dBm:
