Mark,<br><br>Latency has very little effect on streaming video (I assume that this is what you mean when referring to the iView). The only couple of latency-sensitive applications of major interest to a typical consumer that I could think of off the top of my head would be interactive voice and/or video (which needs to have network portion latency to be within ~150-160ms one way to perform absolutely top-notch but can easily tolerate up to 200 ms one way without user noticing too much) and online gaming (where people shoot at each other), where the rule is "the lower the better" without actual lower limit.<br>

</div></div>I'd like to see latency goals mentioned. For a lot of applications, the<br>
bandwidth isn't starting to matter as much as the latency (DNS lookup<br>
RTTs of e.g. 200ms can make the web look slow).<br>
<br>
It might also be worth coming with the a definitive definition of what<br>
"broadband" is, because you can't really judge what suitable<br>
technologies are until you have those parameters. For example, 4G might<br>
be able to go up to speeds of 100Mbps, but if it has a link latency of<br>
100ms-200ms (I don't know, I'm making some estimations based on 3G<br>
experiences), the amount of bandwidth won't matter to people using<br>
interactive or latency sensitive applications.<br>
<br>
One thought I've had is that people should be able to watch ABC iView<br>
as a minimum, as that is our government provided web content source,<br>
which means a minimum of 1.5 Mbps for bandwidth, and I'd say something<br>
like no more than 50-75ms link latency.<br>
