So - Remember - Frequency is simply something that repeats itself over and over again. High frequency simple means there are more cycles per second.Įxample 3 - Low and High frequency example Thats a lot of cycles, eh ? That is the number of cycles 2.4 GHz and 5 GHz (WiFi) uses to transport data from one radio over the air to another radio. We are dealing with simple math - 1 and 5 cycles per second. As the CWNA mentioned, "alternating current is defined as a single change from up to down to up, or as a change from positive, to negative to positive"įive cycles, specified events, measured 1 second in time which equals 5 Hz. One cycle, specified event, is measured 1 second in time which equals 1 Hz. " An oscillation, or cycle, of this alternating current is defined as a single change from up to down to up, or as a change from positive, to negative to positive." - The CWNA definition of cycle v106 This specified event mentioned in the CWNA Study Guide is the cycle. A standard measure of frequency is hertz (Hz)" - The CWNA definition of frequency v106 " Frequency is the number of times a specified event occurs within a specified time interval. There are different types of frequency light, sound and in our case radio frequency (RF). It is very frequent, consistent, and repetitive. Just as the name implies, "frequency", its something that happens over and over and over again.

RF Frequency is a electromagnetic wave using AC (Alternating Current). But you do need to understand the basics.

You don't have to be excellent at RF to be a good WiFi engineer.
