Question 1 of 75
An RF signal sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?
Answer

Suggested Answer

The suggested answer is A.

Refraction is the term that describes the bending of an RF signal as it passes through a medium other than free space. This phenomenon occurs because the signal changes speed when it enters a medium with a different density, causing a change in direction.

Question 2 of 75
What can an impedance mismatch in the RF cables and connectors cause?
Answer

Suggested Answer

The suggested answer is D.

An impedance mismatch in RF cables and connectors can cause excessive Voltage Standing Wave Ratio (VSWR). VSWR is a measure of how efficiently RF power is transmitted from a power source, through a transmission line, to a load. A high VSWR indicates that there is a reflection of the signal back towards the source due to impedance mismatch, which can result in signal loss and potential damage to the equipment.

Question 3 of 75
What factor does not influence the distance at which an RF signal can be effectively received?
Answer

Suggested Answer

The suggested answer is B.

Receiving station's output power does not influence the distance at which an RF signal can be effectively received. The receiving station's radio sensitivity, transmitting station's output power, and free space path loss are all crucial factors that impact the effective receiving distance of an RF signal. The output power of the receiving station does not affect how far away it can receive signals; rather, it influences its transmission capabilities.

Question 4 of 75
A WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss. If the cable is connected to an antenna with 9dBi gain, what is the EIRP at the antenna element?
Answer

Suggested Answer

The suggested answer is C.

First, convert the 50 mW signal to decibels: 50 mW = 10 * log10(50) = 17 dBm. Next, account for the 3 dB cable loss: 17 dBm - 3 dB = 14 dBm. Then, add the 9 dBi antenna gain: 14 dBm + 9 dBi = 23 dBm. Therefore, the EIRP at the antenna element is 23 dBm.

Question 5 of 75
In a long-distance RF link, what statement about Fade Margin is true?
Answer

Suggested Answer

The suggested answer is C.

Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading. This ensures that the RF link remains reliable despite potential variations in signal strength due to environmental factors or other unpredictable conditions.
