LO1, suffer less from attenuation, more fragile - Coggle Diagram

- - - - cheaper
      - susceptible to electromagnetic interference
      - are more likely to suffer from attenuation
      - malleable
      - less likely to break
      - lower bandwidth
    - - higher bandwidth
      - very fast
      - not affected by electromagnetic interference
      - expensive
      - waves of light through a glass tube
      - suffer less from attenuation
      - more fragile
  - - - short range communication
      - limit of 10 metres
      - transfer audio files
      - close proximity is a disadvantage
      - no other hardware is required
    - - replaced by bluetooth
      - requires devicesto be in direct line of sight
      - remote controls
      - short distance
    - - use radio waves
      - large area via microwave towers
      - must be in line of sight of eachother with no obstructions
      - affected by bad weather
      - lead to higher chances of attenuation
    - - send data between devices that are in line of sight of eachother as long as there are no barriers
      - can transmit data up to 2km but bad weather severely affects
      - can be used in space
    - - use point to point multipoint communication
      - delay becuase of distance
    - - Global system for mobile communications
      - mobile phones to connect to a network
      - classified by generations
