Takes data provided and modifies the AC signal using a Modulation technique

Collects the AC signal received from the Transmitter and directs or radiates it out.

Takes the carrier signal received from the antenna and translate the modulated signals into 1s and 0s

Power measured at the connector that provides the input to the antenna

- Transmitter
- All cables
- Connectors
- Any other equipment (grounding, lightning arrestors, amplifiers, attenuators) between the transmitter and the and antenna

Highest RF signal strength that is transmitted from a particular antenna

Relative expression used to represent a difference between two values

Used to compare the output of one antenna to another

decibel gain relative to a dipole antenna

Doubles the distance of the usable signal

Halves the distance of the usable signal

Modulated or unmodulated Background level of radio energy on a specific channel

Difference in decibels between the received signal and the background noise level

The lower the power level that a receiver can successfully process the better the

Power level of an RF signal required to be successfully received by the receiver radio

Sum of all the planned and expected gains and losses from the transmitting radio, through the RF medium, to the receiver radio

Level of desired signal above what is required and is Normally used for outdoor WLAN bridge links
