To see the dBm signal strength of your smartphone, follow the steps below:
1. Make sure Wifi and LTE are turned off.
2. Dial *3001#12345#* and press call.
3. You are now in Field Test Mode. The signal strength will display as a negative
4. Hold down the power button until you see “Slide to Power Off”, then release it. Then hold the Home button until you’re returned to your Home screen. Going forward, you will see your numerical signal strength while you use your phone. By tapping the dBm number displayed, you can see the bars/dots again.
5. To revert back to the signal strength indicator in bars, activate test mode again, then press the home button.
1. Go to “Settings” > “About Phone”, and your numerical signal strength will be available under either “Network” or “Status”, depending on the model of your device.
Q. What are the key differences between a signal booster and the
A. Below is a list of the key differences:
• Signal boosters are typically installed in a fixed location (attached to a house or car) and cannot be easily moved. When a user leaves the coverage area of this location, signal amplification is no longer available and calls may drop. The
• Professional installation and registration
• Signal boosters cost hundreds to thousands of dollars where the
Q. How does the
A. The first of its kind
• The case contains larger antennas than those inside the smartphone. It then uses a “low noise” amplifier enabling the antennas to operate better when receiving low signal.
• The antennas are built into the top of the case to eliminate “death grip” (when a user’s hand blocks signal). Smartphone antennas are typically placed towards the bottom of the device and get covered by hands when in use.
• The amplifier circuitry brings in
Q. Am I exposed to more cellular radiation when I use the
A. Specific Absorption Rate (SAR) measures the rate of radio frequency (RF) energy absorbed by the human body. The FCC’s exposure limit is set at 1.6 watts per kilogram (1.6 W/kg) in SAR and a cell phone’s rating cannot exceed this limit in order to receive FCC certification and be sold in the United States (“Specific Absorption Rate (SAR) for Cellular Telephones” Federal Communications Commission. N.p., 30 Nov. 2015. Web. 06 Dec. 2016). Testing is also conducted with accessories that may impact the SAR rating of the bare smartphone. SAR testing of the
