I have 3 questions:

1. What is the difference between "wireless communication" and "mobile communication"?

2. Also tell me that Communication of ATM networks (used for bank transactions) is an example of which type of communication, “mobile communication" or " or "?

3. Please tell me some web sites (or online resources) related to “wireless communication” as I am working on the project (and on presentation as well) about “wireless communication” in which I have to cover the topics like:-Introduction & overview of “wireless communication”, advantages and disadvantages of “wireless communication”, types of mediums used for wireless, a brief introduction of “wireless technologies”etc. Is there any body to help me? I will be very thankful.

One of the biggest concerns with wireless communication is having data intercepted while it is flying through the air. This link was given to my by a friend http://wepcrack.sourceforge.net/. It talks a little about a program used for cracking wep encryption and has some links to some useful pages. You might also want to look up 802.11b and 802.11g in Google.
