Find Cell Service Provider With Strongest Signal Strength.

Posted by on Feb 09, 2017

You can now check using an RF signal meter, which cell phone service provider signals are strongest in your home, office, business, or workplace. 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. "-65 decibels" is a fairly strong signal which is equivalent to approximately 4 or 5 signal bars in a typical smartphone. 

Accordingly, AT&T Wireless has the weakest signal strength at our test location in a downtown building. "-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. That is definitely not enough to dial out carry on a cellular conversation. 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.

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.

Use the FCC Spectrum Dashboard to find the frequency your Carrier uses to provide cell phone service in your area. Below is an overview of all the frequencies being used in USA - Your Carrier uses one of these to provide service to you:

Band 12 728 to 746 MHz
Band 17 734 to 746 MHz
Band 13 746 to 756 MHz

Channel A 1930 to 1945 MHz
Channel D 1945 to 1950 MHz
Channel B 1950 to 1965 MHz
Channel E 1965 to 1975 MHz
Channel F 1970 to 1975 MHz
Channel C 1975 to 1990 MHz
Channel G 1990 to 1995 MHz

Channel A 870 to 880 MHz
Channel B 880 to 890 MHz
Channel A* 890 to 891.5 MHz
Channel B* 891.5 to 894 MHz

Channel A 2110 to 2120 MHz
Channel B 2120 to 2130 MHz
Channel C 2130 to 2135 MHz
Channel D 2135 to 2140 MHz
Channel E 2140 to 2145 MHz
Channel F 2145 to 2155 MHz

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):

Step 2: Use Cell Phone Signal Meter to check which carrier's frequency is strongest and weakest?

A cell phone signal meter helps detect the signal strength of a signal from any specific frequency being detected in its vicinity. Thus, you can check each frequency obtained from step one to determine which cell phone service provider signals are strongest in your home or office. Be sure to walk across your office or home to ensure that the signal is strong everywhere before deciding to sign up for wireless service with that company. 

If you're stuck with your current carrier with weak signals in your home or business due to a long term contract, why not consider purchasing a cell phone signal booster? Read your rights according to the CTIA Consumer code for cell phone service that all service providers voluntarily comply.
