If my neighbour connects to Optusnet Cable, will that affect me?
No more so than if someone in the next suburb signs up. Cable systems are managed so that there is generally sufficient resources available for most circumstances. Cable modems share both upstream and downstream channels. Cable ISPs will typically deploy a maximum of 2000 subs on any one shared domain or “segment”. Downstream chanels are deployed on unused TV channels so as more subs on each segment take the service additional capacity can be added in the downstream channel, within the limits of available unused TV chanels. A TV channel typicaly carries 27Mbps. So if a segment has only one TV channel configured for data all subs on that segement share the 27Mbps downstream channel. The upstream channel is more troublesome, cable ISPs use the relatively limited spectral space from 5-45Mhz, the so-called return path for their upstream channel. All subs on the segment share this return channel. The return channel is typically less able for any given bandwidth to carry data.
