200Mbps??? I don't THINK so. They don't even have those
speeds available in the infrastructure they would use to
feed BPL. Someone read something wrong somewhere. My ADSL
is 8Mbps, my cable is 10Mbps.
Actually there are two modulation schemes available under DOCIS 1.1,
the slow one is 10Mbps, the fast one is about 36Mbps, and if your
cable modelm is DOCIS compliant, it supports both. I haven't seen a
cable system operator yet that uses the 36Mbps capability however.
BPL promises a fraction of
either of those in reality. With a maximum bandwidth of
75MHz, even with compression, on the main feed, divided
amongst a number of users, actual bandwidth would be around
800Kbps to each user, from all accounts I've read...
200Mbps, indeed.. that would take out not only the entire
HF but also about 80% of VHF...
200Mbps does seem a bit far-fetched, even under tightly
controlled conditions... What's next - OC-192 throughput to
the desktop?
