Finding Cell Tower Locations: The Complete Guide

on September 20, 2017

Where is my cell phone tower location?

At Wilson Amplifiers, we're often asked about coverage maps from AT&T, Verizon, Sprint, T-Mobile, and other carriers on a daily basis. 

While all the major carriers like to show fancy colored maps illustrating their general coverage area across the US, when it comes to your specific cell tower location, you're on your own.

Well, not really. We're here to help.

Today's article will show you all the websites, apps, native tools, and signal meters that will help you find your nearest cell tower.

1. Make Sure Your Carrier Serves Your Area 

It's happened before. Many of our customers either buy a second home, usually a cabin in a remote, rural area, or an RV and find their new place not covered by AT&T, Verizon, or their specific carrier. So before hunting for cell tower maps and locations, make sure your area is part of your carrier's coverage map.

Simply put in your address or zip code for your carrier:

Verizon's Coverage Map

AT&T's Coverage Map

Sprint's Coverage Map

T-Mobile's Coverage Map

Once you can confirm your area is being covered, now it's time to find your cell tower.

2. Websites to Find Your Cell Tower Location 

With these websites put in your zip code or address and it will tell you cell tower locations. While easy and fairly transparent, there's no way to verify if it's 100% accurate. However, it is a good start and when paired with the other techniques we'll mention later, it'll give you everything you need to know.

OpenSignal.com (best of the bunch)

AntennaSearch.com (very good, but takes some time to load)

CellReception.com (good but a bit convoluted)

3. Smartphone Apps to Find Your Cell Tower Location 

These apps use your location and then map out the closest carrier cell tower. Again, it's hard to verify if the information is 100% accurate, but it's a nice tool to have, because it gives you a general idea of nearby cell towers.

OpenSignal:  For iPhone | For Android (best of the bunch)

RF Monitor: For iPhone UPDATED: iOS 11 no longer shows dBm readings on iPhone. Wilson Amplifiers will update with new information when it becomes avaliable.

4. Use Your Smartphone's Antenna to Find Your Cell Tower Location (Highly Recommended Method)

Of course, your phone needs a signal to work, so why not reverse engineer the process to see where the closest cell tower is at? 

But first a short and informative explanation about cell phone signal.

Cell phone signals are measured in dB (decibels). They're basically radio waves, the AM/FM kind. All cellular devices operate within this standard:-50 dB to -120 dB frequency.

-50 dB is considered full strength (full bars). -120 dB is considered a dead zone (no service).

However, it's up to each carrier to define which dB range correlates to the number of bars. Simply put, there's no industry standard to dB signal strength and the number of bars. What's 1 bar on Sprint could be 3 bars on T-Mobile could be 2 bars on Verizon, DESPITE, receiving the exact same signal and performing at the exact same speeds.

Your number of bars is subjective across all carriers!

But dB readings are not subjective. They're pure science and math. The closer you are to -50 dB, the better your signal. The closer to -120 dB, the worse your signal. And your smartphone has the native ability to display dB readings.

Here's How to Access Your dB Signal:

For iPhone Users 

UPDATED: We've received notice that this method is outdated on iOS 11 (on any iPhone) and iPhone 7 & 7 Plus models that use Intel modems instead of Qualcomm models. For other versions of iOS and iPhones that use non-Intel models, this method will still work if you're not using iOS 11. 

  1. Go into Phone Mode

  4. Network or Status

  5. You should see your dB Value

Once you access to your dB reading, walk outside the perimeter of your home. Depending on your carrier & phone model, it takes some time for the phone to refresh, so walk slowly and look for the number closest to -50 dB. After a couple of walk-throughs, you should have a very good idea which area of the house is receiving the best signal, therefore knowing the general direction of your cell tower.

5. Use a Signal Meter to Find Your Cell Tower Location (Best Results)

While using your phone in dB mode is generally a good way to find signal for most people, if you're an installer, contractor, or pro who really wants to be accurate, then getting a signal meter is a no-brainer.

It's a handheld device that pinpoints all 3G & 4G frequencies & bands, displays signal strength in dB, and accurately gives cell tower direction within a 45 to 90-degree spread. A bit costly but worthwhile investment for professional telecom users.

6. Poor Cell Phone Service? Then Learn More About Cell Phone Signal Boosters

If you're suffering from dropped calls, unsent email, slow loading internet, and poor signal, you basically have two options: depend on a landline wifi connection or BOOST your cellular signal. 

Cell phone signal boosters are powerful devices that reach far to the cell tower, pull in the signal, amplify it up to 32X, and then rebroadcast the boosted signal into your home or office.

Here's a quick summary:

  1. Boosts 3G & 4G LTE signal (up to 32x!) for all phones & all carriers.
  2. Covers up to 7,500 sq ft for consumer models, 50,000 sq ft for enterprise models.
  3. Better talk, text, and faster internet. Reliable connection & service.
  4. Complete kit, easy install, no monthly fees.
  5. More bars or YOUR MONEY BACK.
