• Personal Area Network (PAN)


  A network that is spread over a very small area, often covering no more than a few metres, used to connect personal devices
• PAN example

  • Connecting a device without a network connection to one with a network connection, via Bluetooth, USB cable or WiFi
• Ad hoc networks


  • Scalable - more devices can be added at any time

  • Quick to set up - devices can communicate instantly once a connection is established
• Ad hoc networks Drawbacks


  • Less secure - more open and likely to be accessed by attackers
  • Slower - limit to amount of data that can travel at one time
  • No overall control - makes the network disorganised
• Ad hoc networks have security issues • anyone can access, no password needed to join, no encryption
• Ad hoc networks have performance issues: poor signal, limited range, incomplete data transfer
• Ad hoc networks have availability issues: rural areas have less network coverage, mobile networks not as advanced in developing countries, network coverage can be poor in some parts, hills, valleys and thick walls cause blackspots
