Are there compatibility issues with respect to the wired local area network (LAN) backbone?
No. A well-designed wireless network is compatible with the existing wired LAN. This includes traditional LANs that link computers and peripheral devices as part of a short-distance data communications network, as well as more robust LANs that allow users to access databases and programs running on client servers. How is security addressed? The first layer of protection is the network I.D., which must be input before access to the system is allowed. In addition, encryption and authentication features protect data as it is transmitted and protect the network from unauthorized users. For protection of student records, it is possible to limit access to the server with access control lists (ACLs).
