Quick Answer
Check your cellular signal strength by standing outside your home or building, then compare it to the signal strength inside after installing a cellular booster.
Measuring Signal Strength
To determine if your cellular signal is strong enough for boosting, you’ll need to measure the signal strength both inside and outside your home or building. Use a signal strength meter or a free app like OpenSignal or Sensorly to measure the signal strength in decibels (dB) or bars. A good signal strength is typically above -80 dBm.
Understanding Signal Strength Requirements
The Federal Communications Commission (FCC) requires cellular boosters to amplify signals between -50 dBm and -100 dBm. If your outside signal strength is above -80 dBm, you can use a cellular booster to amplify the signal inside your home or building. However, if your outside signal strength is below -80 dBm, you may need to consider other options, such as increasing the antenna height or using a more powerful antenna.
Cellular Booster Installation Considerations
When installing a cellular booster, make sure to follow the manufacturer’s instructions and take into account the size and layout of your home or building. A general rule of thumb is to place the external antenna at least 10 feet above the roofline to minimize signal loss. Also, ensure that the internal antenna is placed in a central location to provide the best coverage throughout the building.
