Security is a major issue in wireless LANs. The 802.11 standard-based LANs do not provide complete security of information. The security is optional and in many installations, this feature is disabled. The encryption key is common to all the nodes and is stored as a file in the computers. If the computer is stolen, the security key is known to the person who stole the computer. Of course, work is going on to improve the security features of wireless LANs.
To plan a LAN, you need to obtain a map of your campus and find out the traffic requirements. If there are two buildings separated by say, more than 500 meters, you need to install two LAN segments and interconnect them. If laying the cable in a building is not feasible, you need to consider wireless LAN option.
