![]() Step 2: Use Cell Phone Signal Meter to check which carrier's frequency is strongest and weakest?Ĭell phone signal meter helps detect the signal strength of a signal from any specific frequency being detected in its vicinity. Or reference the following chart that shows frequencies by mobile technology type plus the slight variation of uplink frequencies (used to send signals from the cellular device to the cell tower) and downlink frequencies (used to send signals from the cell tower to the cellular device): ![]() Below is an overview of all the frequencies being used in USA - Your Carrier uses one of these to provide service to you: Which Cell Phone Service Carrier's Signal Strength Is Weakest or Strongest In Your Home? Step 1: Find the frequency each cell service provider uses in your area.įCC Spectrum Dashboard to find the frequency your Carrier uses to provide cell phone service in your area. The reason for negative numbers is that the RF signal detector shows accurate signal strength in decibels, a scientific measure for signal strength. Either you can ask each carrier to let you take a trial using their phone with service, or you can use the two-step procedure outlined below to accurately check the signal strength each carrier's towers project into your home or place of work or business. That is definitely not enough to dial out carry on a cellular conversation. "-110 decibels" being furthest away from "-50" is equivalent to practically dead zone with "no service" and no bars or at best only one antenna signal bar. "-65 decibels" is a fairly strong signal which is equivalent to approximately 4 or 5 signal bars in a typical smartphone.Īccordingly, AT&T Wireless has the weakest signal strength at our test location in a downtown building. In the sample chart below, T-Mobile shows the strongest cell phone signal because "-65" is closest to "-50" decibels, which is the reference point for peak signal strength. RF signal meter, which cell phone service provider signals are strongest in your home, office, business, or workplace.
