The field test method will differ depending on your operating system. Field Test Mode - Get Reliable Signal Readings Without an App> It's available in both the Mac App Store and Android's Play Store. It can give you dBm readings and shows cell performance on a map. RootMetrics uses user information by testing network performance when consumers use their mobile phones. dBm and antenna or tower location is shown along with the tower’s individual connection strength. This app shows a summary of your mobile network as well as current coverage and signal strength in percentage. Open Signal is available in App Store (Mac) and Android's Play Store. OpenSignal has several maps with information about the coverage of various networks including 3G, 4G (LTE) and 5G. It also shows RSSNR (Reference Signal to Noise Ratio) which measures the noise of the mobile line in dB. Green is good, red or white show connectivity problems. The color-coded map indicates sent and received signal. Network Cell Info covers all cellular networks including LTE, HSPA +, HSPA, WCDMA, EDGE, GSM, CDMA, EVDO. Unfortunately, this one is only compatible with Android. It measures dB level and your nearest cell tower. This app has a band identifier, automated visual logger, advanced LTE, 4G, 5G, CDMA data analyzer, among other features. Best Apps to Find your Signal Strength for Android and iPhone 1. We'll start with the top 5 smartphone apps, and explain field test mode later. There are two main ways to check cell signal strength: the field test method and cell signal apps. -100 to -80 means your signal is below average.-65 to -50 means you have very good signal.-50 means outstanding signal (your phone is probably almost touching the cell tower).dBm readings will be between -50 dBm to -120 dBm, with –50 being full signal and –120 being a dead zone. They aren't one-sided and can't be tampered with by your phone manufacturer or carrier. Decibels measure AM/FM radio waves, which are excellent at traveling long distances, but are easily blocked and can become patchy.ĭBm interpretations are a consistent unit of measurement. Mobile signals are measured in decibels (dB) - a logarithmic unit - while signal strength is measured in decibel-milliwatts (dBm). Fortunately, there is a way of knowing the exact number of decibels (dB) you're getting, for a more precise reading. More bars do usually mean more signal, but there’s no real standard. It's totally arbitrary, and this is true for both 5G and 4G. One bar on AT&T could mean full bars on T-Mobile, which could be two bars on Verizon. That's because they vary, depending on the model of your phone and your cell phone carrier. The cell phone bars reading on your phone isn't reliable.

If you are interested in this app, you can also download it from the app store and give it a shot.Attention business & property owners, installers and integrators WiFi signal strength is represented as an RSSI value in dBm, the closer it is to zero, the stronger the signal is. Then you can compare the signal strength in different places with the help of those screenshots. This feature can help you find the best place with the strongest signal in your house and you can place your router there.ītw, if you tap the “camera” icon, you can make a screenshot of the test page and save it in your phone. It facilitates you to make comparison between those flags which actually represent the Wi-Fi signal strength of those places in your house. If you have tapped “Plus” icon and recorded the signal strength of a certain point before, there will be a blue flag in the heatmap. If you open the heatmap on the lower-left corner, you will find your moving track and the signal strength of the places that you have passed in your house. When you walk around in your house, all the signal strength will be recorded and shown in the heatmap. With AR technology, you can see the result directly. If you want to know the signal strength of a certain point in your house, you can tap the “Plus” icon on the lower-right corner and then point your phone camera at that point, the result will be displayed at once. As you can see from the picture below, the interface is clear and nice. You just need to open the AR mode, walk around in your living room, study-room or bedroom, then it can meter the signal strength and record it in the real world. It gives you a realistic display of the testing results. Here are some features of this app I’d like to highlight.ĪR Signal Master can present the WiFi signal strength in AR technology on your iPhone. AR Signal Master can give you some suggestions. If you buy a router and don’t know where to place it, maybe you should test the signal strength first and then make the decision.
