Thanks to this course, you will be able to understand wireless networks, their standards, how they operate and how you can secure them. When you are learning throughout this course, it will be a great idea to follow without skipping any lessons as the course was built in a sequencial manner. You will start your learning experince by going over different RF Technologies such as Wavelength, Frequency, Amplitude etc. Then you will start learning the RF mathematics which is an essential part of understanding what certain terms mean such as dBi, dBd, watts, milliwats. After that we will start learning about different antennas and we will have a better understanding as we already have the necessary knowledge on RF mathematics and an essential part of antenna calculations.
In this course you will learn all necessary topics for your CWNA Exam.
This course is dedicated for:

The Certified Wireless Network Administrator (CWNA) understands standards and operations of 802.11 wireless networks. Responsibilities include deploying, managing, monitoring and basic troubleshooting of these networks. The CWNA can describe devices and operations of current WLAN technologies.
After completing this course, you will be able to:
– Understand 802.11 / Wi-Fi WLAN Physical and MAC -layer operation in depth.
– Understand and apply the essential concepts of Radio Frequency(RF) technology, including RF planning, RF-related calculations and spread spectrum technologies. Describe and troubleshoot WLAN problems including RF coverage, multipath, hidden nodes and interference problems.
– Perform RF Spectrum Analysis for the 2.4GHz and 5GHz bands. Understand the essential tools and processes used in WiFi Site.
– Survey.
– Describe the rules governing wireless LANs, to comply with local radio regulations for setup and maintenance of WLANs. Work with sophisticated WLAN diagnostic tools from Ekahau, AirMagnet, MetaGeek, Savvius, Tamosoft and more.
– Describe the fundamental operation of wireless LANs, for effective WLAN problem analysis and troubleshooting. Describe the insecurities inherent in IEEE 802.11 WLANs.
– Understand IEEE 802.11b, 802.11g, 802.11a, 802.11n, 802.11ac and 802.11ax (Wi-Fi 6) standards and amendments; and their practical relevance in depth.
– Apply best security practices, including WPA2 and WPA3, to secure Wi-Fi networks for small, medium and large organisations.
– Correctly install, configure and support Wi-Fi adapters, access points, wireless bridges and WLAN antennas.
