  • #ADSL
  • Broadband services use multiple frequency bands to carry signals over wires, adapting to line characteristics.
  • ADSL can work over very poor lines, sometimes just 'a bit of wet string', as demonstrated in an experiment.
  • A test showed ADSL working over a 2m length of salty wet string with speeds of 3½Mb/s downstream.
  • The experiment highlights the importance of addressing faults that manifest as unusually slow speeds.
  • Adding tin cans to both ends of the wet string can provide both voice and broadband services.
