The amplitude of a WiFi wave, or more specifically, the amplitude of an electromagnetic wave used for WiFi communication, is generally not a fixed value. It can vary depending on various factors, including the transmitter power and the distance between the WiFi router (transmitter) and the receiving device.
In WiFi communication, the amplitude of the electromagnetic wave corresponds to the strength or intensity of the signal being transmitted. It represents the magnitude of the electric or magnetic field associated with the wave.
The amplitude of a WiFi wave is typically measured in terms of the electric field strength or power level. It is commonly expressed in units such as volts per meter (V/m) for electric field strength or decibels relative to a reference (dBm) for power level.
However, it's important to note that the exact amplitude of a WiFi wave can vary significantly depending on the specific circumstances and conditions of the wireless network. Signal strength can be influenced by factors such as interference, obstacles, and the presence of other devices. WiFi signals also tend to weaken as the distance from the transmitter increases or when passing through obstacles like walls or furniture.
