ICT is now an essential part of the school environment, used for both educational and administrative purposes. The latest appropriate technological support is needed for all pupils including ports around the school for connection to the schoolÕs network, the internet, multi-media libraries, etc. Pupils with SEN may additionally require wireless/ induction loop aids. It is important that the right infrastructure is provided.

Network installations Networking is now commonplace, allowing greater flexibility with the ability to use any machine, better management and wider access to shared resources. Wireless systems are developing rapidly, in many cases providing an affordable alternative to cabled networks.
It is important to consider carefully a schoolÕs needs before making final decisions. This will include looking at the overall installation cost, compatibility with any existing system and curriculum requirements. In many cases a combination of cabled and wireless connections may offer the most flexible solution. Whichever system is chosen it is vital to fully investigate the alternatives and seek expert help with installation.

Wireless
In a wireless network a group of portable computers (usually laptops) are connected to the network by means of radio receiver cards in the PCs which receive data from radio transmitter access points suitably spaced around the school. A single node would typically serve twelve secondary school users simultaneously, depending on usersÕ activity.
Wireless systems can be used with high specification laptops (that do most of the processing rather than relying on a server). An alternative approach being trialled in some schools uses thin client laptops with a higher specification server to process the data centrally. A fat client network, as is often used, is more difficult to upgrade than a thin client network as every laptop has to be upgraded rather than simply upgrading the network software on the server. However, this also depends on the configuration. The newer Windows 2000 supports thin client networking and could lead to more widespread adoption of this type of network. The costs of the laptops is lower in a thin client network. Advantages of a wireless network include:
• Flexibility: computers can be used anywhere within range of the node;
• Ease (and speed) of installation: useful where cabling is difficult or expensive;
• Clean appearance: no visible trunking and less need for suspended ceilings and raised floors.
