"Face it, dialup uses a century old technology. "
This may be true for the phone network itself , but the way dailup works has changed alot over the years , originally it did work by sending bit by bit without compression. But now the data is compressed and patterned ( its called PSK IIRC , Phase shift something .. its been along time since learnt about it
) where the carrier wave is not manipulated to represent a high or low bit but instead manipulated to represent groups of bits increasing the bandwidth many times over.
