Mới! Khóa đào tạo Quản trị viên Mạng không dây CWNA-109

In this course you will learn all necessary topics for your CWNA-109 Exam. You will also learn more topics that you will need for your CWS CWT exams and you will gain immense knowledge for the fundamentals for your CWDP CWSP exams.

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.
