https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/23231-powervalues-23231.htmlIn a wireless network environment, the following parameters are calculated using the numerical values of the transmitter power level, cable loss, and antenna gain:
Transmitter Power Level: It refers to the amount of power emitted by the wireless transmitter, which is measured in decibels-milliwatt (dBm).
Cable Loss: It refers to the loss of signal power that occurs as the radio signal travels through the coaxial cable that connects the transmitter to the antenna. This loss is measured in decibels (dB).
Antenna Gain: It refers to the ability of the antenna to focus the radio signal in a particular direction, which is measured in decibels isotropic (dBi).
The calculated value from these parameters is Effective Isotropic Radiated Power (EIRP) and is expressed in dBm.
EIRP is the measure of the actual power that is emitted by an antenna in a specific direction. It is calculated by adding the transmitter power level and the antenna gain and subtracting the cable loss from the result. Mathematically, EIRP = Transmitter Power Level + Antenna Gain - Cable Loss.
EIRP is an important parameter because it is used to determine the coverage area of a wireless network. It is also used to calculate the maximum power level that can be transmitted by a wireless device, which is regulated by government agencies to avoid interference with other wireless devices and services.
Therefore, the correct answer to the given question is option C: EIRP.
