Hi:

Is it physically possible to for dial-up internet connection to reach a
speed of 1 Gbps by using a baud of 1-symbol-per-second [to conserve
bandwidth] but 1-billion-bits-per-symbol?

Each symbol carries a billion bits bits but with only 1 baud.

bps = baud X number of bits per baud.

Is this physically-possible?


Thanks,

Radium

There's a billion bits encoded in that one eight-bit character.

You just have to find the right decompression table. If it decodes to
an Ann Coulter book, you're using the wrong table.
