Cryptography can be used for many purposes, but there are two types of cryptographic algorithms you need to understand, symmetric and asymmetric.

One of the biggest concerns for wireless networking is maintaining a reliable connection. This can be difficult in densely populated areas where many other wireless networks are already in use or where interference is present. However, there is an easy method to avoid conflicts and poor signals: wireless frequency analysis.
