What is the wireless received signal strength indicator?
A . The value given to the strength of the wireless signal received compared to the noise level
B . The value of how strong the wireless signal Is leaving the antenna using transmit power, cable loss, and antenna gain
C . The value of how much wireless signal is lost over a defined amount of distance
D . The value of how strong a tireless signal is receded, measured in dBm

Answer: D

Explanation:

RSSI, or “Received Signal Strength Indicator,” is a measurement of how well your device can hear a signal from an access point or router. It’s a value that is useful for determining if you have enough signal to get a good wireless connection.

This value is measured in decibels (dBm) from 0 (zero) to -120 (minus 120). The closer to 0 (zero) the stronger the signal is which means it’s better, typically voice networks require a -65db or better signal level while a data network needs -80db or better.
