Modulation is the way that a signal is modified to represent bits, allowing it to be sent across the radio to the receiver using the hardware and software available. This is done by utilising three basic elements that effect the waveform: frequency, amplitude, and phase. Frequency is based on the timing between the signals and is usually measured by the number of wave cycles in each time frame (for example one second). An example is 1Hz represents 1 wave being sent with that cycle, while 1KHz (1,000 Hz) shows that 1,000 cycles have happened in that given space. This is the same even for the 2.4Ghz and 5Ghz frequencies, as you can see the 5Ghz will pass nearly double the amount of waves pre cycle then 2.4Ghz, but as you may recall from my post about home Wi-Fi, 5Ghz travels less distance due to its higher frequency.     You tend to find frequency is not used within a wireless environment as switching between different frequencies means you could start interfering with other devic
