AVC gives a complete visibility of applications in the network and allows the administrator to take some action on the same. The key use cases for NBAR AVC are capacity planning, network usage base lining and better understanding of what applications are consuming bandwidth.

RF Signals and Modulation
Number of times the signal makes one complete cycle in a second. Measured in Hertz (Cycle per second).
Radio Frequency = 3kHz to 300 GHz.
2.4 GHz band: From 2.400 to 2.4835 GHz. Has a total of 14 channels (1 to 14) spaced 0.005 GHz (or 5 MHz) apart.
- 5.150 to 5.250 GHz
- 5.250 to 5.350 GHz
- 5.470 to 5.725 GHz
- 5.725 to 5.825 GHz
Signal bandwidth – the actual frequency range needed for the transmitted signal.
Phase – measure of shift in time relative to the start of a cycle.Measured in degrees.
In Phase – two identical signals are produced at exactly the same time and have matching cycles.
Out of Phase – Signal that is delayed relative to the other.
Physical distance that a wave travels over one complete cycle.
