Two Tales of DSL | POTs and PANs: But the problem for all DSL providers is that within a few years the demand for broadband speed is going to exceed their capabilities. The statistic that I always like to quote is that household demand for broadband speeds doubles about every three years. This has happened since the earliest days of dial-up.
