Wireless Networking in Secondary Schools
Baglan IT Centre has now started trials of secure wireless networking in secondary schools within Neath Port Talbot. The method of connection has been developed around the strongest encryption algorithms available, combined with hiding the network identity and security certificates.

Design Issues

  • Wireless networking should not be used as a substitute for wired networks as their maximum throughput is 54mbps shared between all workstations compared to a standard wired connection of 100mbps dedicated to each network point.
  • The wireless access points (WAP) can only really handle four simultaneous "power" connections at one time, so more than one WAP may be needed for an installation. They can however, handle a whole class group working on activities such as word processing and spreadsheets.
  • The ability for signals to travel through walls, ceilings within a building is limited and is dependent on what materials are used in its construction. A system which is self contained within a room will work fine but for anything more than this external consultants will need to be brought in for professional advice.
  • Don't think of wireless as a cheap solution to a short-term cabling problem. To get the level of encryption and security required for the network the WAP devices cost in excess of £400 each. Bringing in external consultancy can also be very expensive.

Suggested Uses for Wireless in School

  • In the school hall or gymnasium where a network point may not be in a convenient location.
  • To provide a mobile network facility for classrooms - laptop workstations are rolled into the classroom for the lesson and moved to another location after the lesson.
  • In the staff room, to allow teachers to work during their PPA time without the worry of having to find a suitable network point to plug into.
  • Ability for teachers to record assessment data for tracking using SIMS Assessment Manager whilst away from the school network.
  • In PE settings where data networking is not provided.
