Re: What is up with CABLE? In my opinion, DSL's advantage is upload. At some point, we're all shared and I think cable has massive download bandwidth -- enough to match DSL's "less shared" architecture. The real problem is on the upstream side. Because on cable that too is shared, everyone gets assigned a time slot on which to transmit. If everyone talked at once, it would trash everything. DSL doesn't have this problem and should eventually be able to create upload speeds that cable simply cannot match, no matter what modulation tricks they use.
Of course having more doesn't mean anything if it isn't what people want. I suspect that most users are still very asynchronous -- using far more downstream capacity than upstream capacity. Certainly peer-to-peer file trading is reason enough but I suspect the majority will need some other application that thrives on upstream bandwidth before it becomes a driver toward synchronous speed packages (downstream = upstream speed packages). |
