Acoustimeter - Measuring the VR900 wi-fi router (2.4 and 5 Ghz), in my bedroom
Measured in this video (recorded in July 9, 2018): 1) My bedroom. There's a wi-fi router in the other next to it (Archer C8, with beacon interval configured to 1000 instead of 100, and also "Transmit Power" to Middle instead of High). As you can see the radiation levels are lower this way. The Archer C8 is in the other bedroom separated by a wall. The Archer C8 has both the 2.4 and 5 Ghz networks enabled, so I can choose between them. Go to 01:30 and you'll see the Acoustimeter detecting the Archer C8 from the other room. That part of the wall is right in the path of where the Archer is located. Also check 20:40 . 2) In my desk (also in my bedroom) I have a second router: the VR900. Wi-fi is totally disabled for both 2.4 and 5 Ghz. In this video I measured the radiation levels if I enabled the wi-fi feature in the VR900. In the VR900 case I configured Transmit Power to HIGH and beacon interval for the default value of 100. Go to 03:10 . That's when I enabled the 2.4 Ghz in the VR900. Imediatelly you'll see radiation increases in my room. As you can see the 5 Ghz network is not active. 3) Go to 07:00 That's when I enable the 5 GHz network. So beginning at 7 minutes the router is at full power and we have both the 2.4 and 5 Ghz networks available. 4) Go to 12:45 . I decide to turn off the 2.4 GHz network from the VR900. Meaning the VR900 will only broadcast the 5 GHz in my bedroom. As you can see radiation levels dropped A LOT. At 13:40 you will notice that if I hold the Acoustimeter VERY CLOSE to the VR900 the levels can increase to 2 and even 4 V/m, but at ANY OTHER DISTANCE this meter does not recognize the 5 GHz is still enabled. Or if it is I couldn't tell from the readings. 5) At 17:50 the 5 GHz is turned off, too, in the VR900. Meaning my bedroom is now only receiving radiation from the Archer C8 and any other sources, such as neighbors. As you can see at 18:55 the Acoustimeter does not detect anything anymore, when close to the VR900. That indicates the 5 Ghz is recognized by the meter, yet it doesn't explain the huge drop in the readings. 6) 20:40 - this is the Archer C8 location, in the other room. The signals are strong in this area (almost outside my bedroom) because the Archer C8 is located in a direct line from the wall. Also check 01:30 .
