In addition, you will have several maps with information about the coverage of networks that we have around us for 2G, 3G, and 4G LTE. The first thing you see when running the application is a summary of your mobile network. In the upper part, we will see an intensity meter that will indicate the coverage. Also, a graph in which we can see the average coverage we have registered. We can also see the percentage of intensity, the average of said percentage and the dBm of the signal.
It also has a map which shows the antenna's location as well as information regarding the state of the connection. RootMetrics offers scientifically compiled mobile network performance information to consumers. The company captures user information by testing network performance when consumers use their mobile phone for voice or data communications.
It can give you dBm readings and determines cell performance on a map. The Field Test menu has had some variations on each iPhone version; nevertheless, this mini-guide should work on iOS 11, 12, or The first thing you need to do is open the Control Center or go the Settings app. Remember to turn off your Wi-Fi. Then press call and you will see the Field Test menu. Then look for either "rsrp0" or "rsrp1". One of those should have a negative number, which means your signal strength in decibels.
Field test mode on Android varies by phone model and Android OS version. However, you can generally find it under the Settings menu. Got your dBm reading through Field Test mode or an app? Can these phone manufacturers be trusted? Fortunately, there's a better way to measure your cell phone signal and that's by looking at decibels dB — a logarithmic signal unit used to quantify the ratio between two power levels.
More specifically, decibel milliwatts dBm — a value used to denote an exact power level unit expressed in decibels with respect to one milliwatt. Cell phone signals are measured in dB. The signal strength of those cellular waves in a specific location, such as outside your house, inside your apartment , or on your commute to work, are measured in dBm, which are always displayed as negative numbers.
Many smartphones have the ability to display dBm readings, or they can be obtained through cell signal analyzer apps. All cellular devices operate within this strength range: dBm to dBm. All cell phone signals in the US and Canada need to operate within this range to work. The closer you are to dBm, the better your signal.
The closer to dBm, the worse your signal. Unfortunately, recent iPhone models have removed the ability to view dBm levels. Therefore, there is no perfectly accurate way to obtain your signal strength with an iPhone. The next best method is performing a speed test around areas inside and outside your home. However, if you truly want to find out what your exact dBm readings are, you can use an Android device to obtain your dBm readings.
This can be achieved either by purchasing an inexpensive Android phone or borrowing one from a friend. Dark mode support available. The best app to find carrier towers around you! Thank you for all your support. Please help us further improve the community. Plus… The FAQ says that ads have been disabled for everyone, but the app will still happily accept payment to remove them. This needs to change! As it is, the app is in extreme danger of driving users away by acting too desperate for money.
Well several issues. First it is a promising app, seems to find towers accurately and that is what it is meant to do. However if I click restore purchases, it does. But I have to do this over and over again. Then the app wants me to rate it, fine. But when I want support? Error time. Come on devs, seriously? The devs need to know that the customer is busy as well and has chosen to use their product. Get a grip! Hello, thank you for taking the time to provide feedback. When you first download the app and provide access to your GPS location, a map with surrounding towers is immediately shown without interaction or additional purchases.
Only additional features require an in-app purchase all listed in the FAQ section.
