Exam Syllabus

The CWNA-108 exam covers seven knowledge domains. Each of these areas has detailed topics and subtopics that must be understood to improve your performance in the certification test. The highlights of these sections are as follows:

RF Technologies: 15%

This is the first topic to deal with that will evaluate the following skills that you need to possess:

• Apply the fundamental concepts of the Radio Frequency measurement and mathematics: This subtopic focuses on Watt & milliwatt, RSSI, SNR, Decibel, Noise floor, dBm & dBi, as well as EIRP;
• Describe and use the functionality of the RF antennas, accessories, and antenna systems: The area includes highly directional antennas, Omni-directional and semi-directional antennas, RF connectors & cables, Antenna orientation, grounding wires/rods, and Lightning arrestors.
• Establish RF signal attributes to antennas: This means that you should know about passive gain, MINO, radio chains, polarization, beamwidths, transmit beamforming, passive gain, spatial multiplexing, and maximal ratio combining;
• Identify and describe the basic attributes of Radio Frequency (RF) and RF behaviors: The concepts covered in this area include multipath & RF interference, attenuation, amplification, return loss, gain & loss, free space path loss, and absorption, among others;
