Maurice has hypothesized that the noises may be from electromagnetic waves coming from aurora, natural light displays mostly seen in the Arctic and Antarctic skies [source: Huffington Post]. 7: The Lincolnshire Poacher This shortwave radio belonged to Soviet spy Rudolf Abel. He used it to ...
As WLANs use radio signals to transmit service data, radio waves in the air are attenuated due to the impact of the surrounding environment. If the Wi-Fi speed is low, check the Wi-Fi signal strength. The strength of Wi-Fi signals received by a STA directly affects the Wi-Fi sp...
A television or a radio broadcast uses a sound signal or other images according to broadcast channels. Apparatuses which use the images, the sound, or the signals respectively use the different image, sound, or signal. The apparatus transmits and receives the signals as the radio wave of the...

In summary, to stop or reduce ultrasonic sound wave devices, one can employ several strategies: moving away from the source, using soundproofing materials to block the waves, adjusting the device settings if possible, or utilizing white noise machines to mask the ultrasonic sounds. Additionally, ...
To ensure a stable Wi-Fi connection: The router should be located near the top of the rack and away from any other gear that may use radio waves in the same 2.4 GHz or 5 GHz range. Note that rack-mount computers or laptops placed directly above routers may cause wireless interference. ...
