1 byte is 8 bits, so 1.5 Mbytes/s would be 12 Mbits/s. I just
cross-checked and you are correct, USB1 -is- 12 Mbit/s.
Investigating Bigpond's cable throughput rates from here on
another continent, I see that according to
http://www.bigpond.com/broadband/access/cable/
BigPond Broadband Cable can be up to 50 times faster than a
standard 56.6kbps (kilobits per second) dial-up internet
connection~.
On a 56.6 Kbps modem, you don't actually get 56.6 Kbps throughput
because a fair bit of it is overhead; on the other hand, the build in
compression can allow you to get higher speeds than that, depending
on the kind of file you are downloading. 50 times 56.6 would be 2830 Kbps
or 2.83 Mbit/s, but because of the above factors, we can't trust that
calculation.
At that speed, you could download enough data to fill a floppy
disc in less than 5 seconds or a four-minute MP3 music file in
less than 12 seconds.
A standard floppy disk is 1.44 Mbyte. They say less than 5 seconds,
so the rate is better than 1.44 Mbyte * 8 bits/byte / 5 seconds = 2.3 Mbit/s
but we can presume they would have said "less than 4 seconds" if the
rate were that good, so 1.44 Mbyte * 8 bits/byte / 4 seconds = 2.88 Mbit/s
is the upper limit.
Something up to 2.88 Mbit/s would fit easily into 802.11b wireless link
that was running unshared at full connection speed.
