             The purpose of this report is to analyse the current John Paul College network with the objective of improving the system. The report will contain information regarding the present system in place covering the advantages and disadvantages of the network. It will also address the changes that will be implemented to enhance the current network. .
             2.0 The Current Network.
             The John Paul College network is almost completely wireless. Exceptions to this include staff, desktop computers in the primary school and senior school, all being connected by CAT5 cable. The wireless network reaches all parts of the college campus from the Coleman Centre to Sick Bay to the JPIC. (Refer to Appendix A).
             The current data transfer rate present throughout the campus is 11Mbps (MegaBits Per Second). A typical installation would have a wireless access point connected to a classroom network point, usually mounted upon a wall near the roof of the room. Currently the school employs two types of wireless connections points, one for 64 persons and more recently, 128 person wireless access points. Each portable computer that wishes to connect to the college network has to have a wireless card, usually in the PCMCIA (Personal Computer Memory Card International Association) slot.
             At the moment the hierarchical structure of the school involves five servers, each handling a different aspect of the network from mail to file storage. Recently the school purchased a SAN (Storage Area Network) increasing the storage capacity of the school to just over 1.5 terabytes. Connected to the servers are switches, which transfer the information to the appropriate wireless connection points. The wireless connection points distribute the signal to all the individual nodes. At present the school has over 50 wireless connection points and over 30 switches. The network at the school can accommodate for over 1100 students with 1400 students having access to the network.
