When the strength of your cell phone signal matters most, skip the bars on your screen and opt for the master precision of dBm signal strength measurements.
Whether it’s choosing the strength of your signal booster or figuring out where to install it for optimal efficiency, apps like Network Cell Info make it easy to monitor and measure signal strength in real time.
Signal strength measurements can also be attained natively. Android phones offer a decibel-reading function in their settings, while some iPhones can access decibel information via field test mode. Simply “call” the number *3001#12345#* from the keypad and look for rsrp results to identify signal strength results.
An accurate reading of your dBm signal strength will not only optimize the performance of your cell phone booster antennas and amplifiers, but you’ll also sound like a true tech wizard the next time your friends are flailing their phones around in search of those elusive bars.
