Question

Given an access point with 100 mW of output power connected through a cable with 3 dB of loss to the antenna with a 10 dBi gain, what is the approximate Equivalent Isotropically Radiated Power (EIRP) level from the antenna in mW? - (WRONG ) 100mW

Answer 1

The approximate Equivalent Isotropically Radiated Power (EIRP) level from the antenna is 109.5 mW.

Step-by-step explanation:

To calculate the Equivalent Isotropically Radiated Power (EIRP) level from the antenna, we need to take into account the output power of the access point, the cable loss, and the antenna gain.

The EIRP is calculated by adding the output power and the antenna gain, and then subtracting the cable loss. In this case, the output power is 100 mW, the cable loss is 3 dB (which is equivalent to a factor of 0.5), and the antenna gain is 10 dBi (which is equivalent to a factor of 10).

Using the formula EIRP = Output power + Antenna gain - Cable loss, we can calculate the EIRP:

EIRP = 100 mW + 10 - 0.5 = 109.5 mW

Therefore, the approximate EIRP level from the antenna is 109.5 mW.
