Samsung Galaxy Note 9 Safety Tip: Turning Off Wi-Fi and Bluetooth Reduces Radiation.

This SAR chart reveals how turning off Wi-Fi and Bluetooth on your Samsung Galaxy Note 9 can significantly reduce your exposure to radiation. Our SAR comparison chart shows that by simply turning off these transmitters, you can lower the RF radiation exposure to your head by %, and you can lower exposure to the body by %, when considering these differences between cellular-only (Wi-Fi/Bluetooth OFF) and simultaneous use exposure (Wi-Fi/Bluetooth ON), a wise way to reduce excessive phone radiation is to tap off unnecessary transmitters when not in use. Additionally, when using your phone as a hotspot, turning off Bluetooth can reduce your exposure by up to 0% according to the FCC SAR report for device number A3LSMN960U.

BODY0.76 W/kg% W/kg
HOTSPOT1.35 W/kg0%1.35 W/kg

The Specific Absorption Rate (SAR) of a mobile device measures the amount of radio frequency energy absorbed by the body during device usage.

The SAR values for the galaxy-note-9 (FCC ID A3LSMN960U) are as follows:

  • 0.27 W/kg when held at the head with cellular transmission only
  • 0.76 W/kg when worn on the body with cellular transmission only
  • 1.35 W/kg when used as a Hotspot or Airplay
  • when used as a Hotspot simultaneously with other transmitters active.

2018 FCC Specific Absorption Rate (SAR) Report For Manufacturer Submitted Model Samsung Galaxy Note 9 FCC ID A3LSMG960U


According to test reports filed with the Federal Communications Commission (FCC), the Specific Absorption Rate (SAR) for the Samsung Galaxy Note 9 is 0.33 watts per kilogram (w/kg) at your head, and 1.03 w/kg when worn on your body. The Samsung Galaxy Note 9 hotspot SAR is 1.39 W/kg. The SAR for simultaneous transmission (cellular, Wi-Fi and Bluetooth) for the Samsung Galaxy Note 9 is 1.59 W/kg when used as a hotspot simultaneously with all other transmitters active.

All SAR levels reported for the Samsung Galaxy Note 9 to the FCC are averaged over one gram of body tissue corresponding to the maximum allowable level of 1.6 w/kg. The SAR levels will vary depending upon your specific cell phone carrier (e.g., AT&T, Sprint, T-Mobile, or Verizon).

The Samsung Galaxy Note 9 minimum separation distance for body-worn testing was 15 mm, that requires a smartphone user to maintain over 1/2 inch minimum separation (15 mm = 0.59 in) or 1.5 cm for SAR safety compliance.

Galaxy Note 9 SAR compliance for body-worn operating configurations is limited to the specific configurations tested for this filing.  Body-worn operations are restricted to belt-clips, holsters or similar accessories that have no metallic component in the assembly and must provide at least 1.5 cm separation between the device and the user’s body.  End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance.

The highest reported Galaxy Note 9 SAR levels for the head, body-worn accessory, product specific (wireless router), and simultaneous transmission use conditions are 0.33 W/kg, 1.03 W/kg, 1.39 W/kg, and 1.59 W/kg, respectively
