A DSL of 500 Mbps over copper wire
Ericsson has just unveiled a new DSL based technology that is capable of reaching transmission speeds of around 500 Mbps over copper wiring.
Nevertheless, this technology only works by bonding 6 pairs of copper wiring (which would only be possible in homes with 6 different telephone lines). And the length of the copper wiring should be rather short, so the target homes should be near the local exchange.
The expensive optic fiber is the future, but new DSL approaches as this one are always welcome. Practical implementations will never reach this 500 Mbps bandwidth, but we should expect a DSL speed increment in the near future.
