- 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.
