350-401 Exam - Question 639


EIRP (Effective Isotropic Radiated Power) is the actual amount of signal leaving the antenna. It is a measurement value in db and is based on which three components? (Choose three.)

Show Answer
Correct Answer: ACD

To determine EIRP (Effective Isotropic Radiated Power), you need to consider three key components: Transmit Power, Cable Loss, and Antenna Gain. Transmit Power refers to the initial power output from the transmitter. Cable Loss represents the reductions in signal strength through the transmission medium (cables). Antenna Gain measures the increase in signal strength provided by the antenna's design. These three factors together define the actual signal strength emitted from the antenna, making them crucial for calculating EIRP.

provided answer is correct. The radiated (transmitted) power is rated in either dBm or W. Power that comes off an antenna is measured as effective isotropic radiated power (EIRP). EIRP is the value that regulatory agencies, such as the FCC or European Telecommunications Standards Institute (ETSI), use to determine and measure power limits in applications such as 2.4-GHz or 5-GHz wireless equipment. In order to calculate EIRP, add the transmitter power (in dBm) to the antenna gain (in dBi) and subtract any cable losses (in dB). reference: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/23231-powervalues-23231.html
