HPE7-A01 · Question #92
You are doing tests in your lab and with the following equipment specifications: - AP1 has a radio that generates a 20 dBm signal - AP2 has a radio that generates a 8 dBm signal - AP1 has an antenna…
The correct answer is D. 24 dBm. To calculate the Equivalent Isotropic Radiated Power (EIRP), you use the following formula: EIRP = Transmit Power + Antenna Gain − Cable Loss For AP1, the values are: Transmit Power = 20 dBm Antenna Gain = 7 dBi Cable Loss = 3 dB

Question
You are doing tests in your lab and with the following equipment specifications:
- AP1 has a radio that generates a 20 dBm signal
- AP2 has a radio that generates a 8 dBm signal
- AP1 has an antenna with a gain of 7 dBI.
- AP2 has an antenna with a gain of 12 dBI.
- The antenna cable for AP1 has a 3 dB loss
- The antenna cable for AP2 has a 3 dB loss.
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for AP1?
Options
- A2 dBm
- B8 dBm
- C22 dBm
- D24 dBm
