yes, there are some limitations and drawbacks to consider when using kilohertz frequencies. one limitation is that higher frequencies, such as those in the kilohertz range, tend to have shorter wavelengths, making them more susceptible to attenuation and interference. this means that kilohertz signals...
Although the 5 GHz frequency band can bring a higher transmission speed, the signal attenuation is larger. Therefore, the transmission distance is shorter than that of the 2.4 GHz frequency band. When deploying a high-density wireless network, the 2.4 GHz frequency band is not only used to be...
EMI / RFI is short for Electromagnetic Interference / Radio Frequency Interference. Technically, both terms refer to the same phenomena where electromagnetic waves affect the operation of electronic devices.
However, ferrite is the most common material applied to the walls of anechoic chambers for EMC testing. Ferrite causes magnetic loss (natural resonance, domain wall resonance, etc.) in high-frequency AC magnetic fields. Ferrite-based radio wave absorbers make use of this property. Examples ...
Millimeter wave, or mmWave, is a part of the radio frequency spectrum between 20 GHz and 100 GHz. Get started with examples and documentation.
WiFi(Wi-Fi) is a wireless LAN standard, part of IEEE 802.11, for communication among different devices. It is a kind of radio wave, the same as Bluetooth and cellular networks, used for device communication on a small scale.

1. Distance: Wi-Fi transmission distance is a crucial factor affecting wireless speed. Wi-Fi operates through radio waves, and these waves experience attenuation due to their physical properties. When radio waves encounter obstacles, they undergo reflection, refraction, or diffraction, limiting the Wi...
For example ground wave propagation, used for LF and some MF transmissions is often better when a vertically polarised antenna is used. Studies have shown that the signal propagate with less attenuation when they are vertically polarised. For HF the propagation modes mean that signals of either ...
