Otherwise, it’s your phone that may have trouble. However, if your phone signal strength is above -90 dBm, but the phone call is intermittent, it is not the blame to signal reception. Indicates signals for communication is definitely dropped. Indicates a very weak signal, phone talking may be intermittent. Indicates a weak signal, basic communication is possible. Indicates good signal, phone talking and video connection are both OK. Indicates excellent signal, fluent call reception, and network connection. The following is a rough guide to signal strength (dBm), based on the 2G network: dBm range (dBm) You will see two numbers that signify the same signal strength but in a different unit, the first indicates cell phone signal strength (dBm), with 0 – 50dBm representing excellent signal strength. Go to settings and do with the following process: Settings – About phone – Status – Network. Methods of checking signal strength on Android phonesįor Android phones, we recommend two mainly-used methods for checking the signal strength.Here, we’re about to introduce methods on how to check the signal strength on your Android phones and your iPhones. To measure the dBm reading on your phone you’ll need to put your phone into field check mode. How to measure the dBm reading of your phone? If the signal is below -110 dBm, you likely won’t have cell service. Typically, a reading of -50 is the strongest signal, while the reading below -100 dBm is considered to be very weak. The closer to zero the reading, the stronger the cellular signal. The reading of dBm is expressed as a negative number. How can we measure our cell phone signal received from the cellular tower? The answer is decibel-milliwatts, or dBm – a standard unit of measure used to define signal strength in wire and cables at radio and audio frequencies.
There will be quite a bit of fluctuation between the bars on one phone to another phone owing to the different cell phone manufacturers (Apple, Samsung, Sony, etc.) Why is it?Īctually, signal bars are merely an aesthetic representation of the signal strength. But you might face such occasion during daily life that your cell phone reminds you of losing service while the signal bar you can see is above 3 or more. For the most time, we get used to evaluating signal strength by comparing how many signal bars or dots on our cell phone screen.
