Frequently Asked Questions

It supports hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and terahertz (THz).

Frequency is the number of cycles per second of a periodic wave. It is measured in hertz (Hz), where 1 Hz means one cycle per second.

Frequency and wavelength are inversely related. Higher frequency means shorter wavelength. The relationship is: speed = frequency × wavelength.

Humans can typically hear frequencies from 20 Hz to 20,000 Hz (20 kHz). This range decreases with age.

Most countries use 50 Hz for AC power (Europe, Asia, Africa). The US, Canada, and parts of South America use 60 Hz.

Wi-Fi operates at 2.4 GHz and 5 GHz. Wi-Fi 6E also uses the 6 GHz band. 5G mobile networks use frequencies from 600 MHz to 86 GHz.

Period (T) is the time for one complete cycle. Frequency (f) = 1/T. A signal with a period of 0.01 seconds has a frequency of 100 Hz.
