    He's still around, just breaking more expensive computers than we get to hear about, is all Hi

    NBN - Is it too expensive?

    Yep i've got plenty of those too. They're fucking high compression.

    NBN - Is it too expensive?

    Yep, i've done stadium jobs too. Not 4G in that case, but high density Wi-Fi. And yes, DAS systems and Microcells can definitely help in that regard. That doesn't mean there isn't noise, just that we can control it enough (usually only just) for it to work at its limits. Stadiums do have the advantage of basically being a big faraday cage though, so you can design them with almost an expectation of nothing buy background noise levels in the area, compared to the big wide world outside, like suburb/city scale infrastructure has to deal with. No, not every home. eg, if i wasn't a heavy user (due to both personal and work requirements) i wouldn't need 100mbit. But 35Mbit is limiting what i'm able to do, particularly in my case due to the only 7MBit upload speed. So sure, lets say FHD video is 5-8MBit as you claim (super high compression there), and a kid needs to upload a video to either youtube or the schools online systems, then your internet is effectively unusable (in my example) until such video is uploaded. That's if you've got one kid. Sadly, there are many breeders in this world, so some families have more than one kid. Crazy, can't see why myself... but can't help some people.

    NBN - Is it too expensive?

    You said it. Nah, it actually took about 3 weeks and 7 tech visits. I managed to identify the fault in the first instance, but it took them that long to actually go through their processes to come to the same conclusion i did on my original day of cutover. And sure, it was a 1000% improvement, but when you start at shit, any improvement is a step up. I still get starved for speed. Granted, i'm not the 'normal' use case, but my current level of load will be normal soon - and i'm just one guy, no family. I know many people in my area (broadly speaking - a few suburbs around me) with families, who don't have the bandwidth they 'want' (for various reasons) a night. Mostly regarding study (video is a massive part of schooling these days) and entertainment. They could pay the ~20k to get FTTH connected, sure. As for wireless tech vs fibre. Think of it this way: You can fit *best case*, assuming future technologies are awesome, 1MHz-80,000GHz in a shared wireless medium. Realistically obviously much less, so lets talk Carrier bands + ISM. 800-1000MHz, 1700-2600MHz, a few gaps for 900MHz, 2400MHz and 5800MHz ISM bands, but obviously higher the frequency, shorter the distance (not always a bad thing, but not good for regional). In the second example above, you can do that frequency band, plus more (due to no radiating RF) on a single wavelength of fibre. We have commodity hardware now that'll do 5-2400MHz over fibre. It's common. Give it say 5 years and we'll probably see it go to 5.8GHz too, to encompass DAS over the same bands, without needing LO circuits for mixing. Using CWDM, 16 wavelengths of such a system is possible, so 16x the 'wireless' spectrum. How you do your return path changes total bandwidth of course, being either FDM or TDM, your call. Using DWDM, though unlikely to be required yet, you could do *with current tech* nearly 200 sets of 5-2400MHz. Now we both know (speaking to Leo of course) that the above requirements are more than we need now. And there's also no doubt that wireless tech will improve. I see the latest advancements in what i do as well. That's not to say though that those EXACT enhancements in wireless tech don't flow directly onto fibre tech. If you can run a 4096 QAM carrier over copper, i can do it over fibre, with less loss and degradation. Ignoring the other possibilities of a fibre deep network like additional services. I've already designed for clients an integrated network which encompasses GPON, NGPON, DOCSIS (as separate services on the same fibre), DAS (multicarrier + 2 way radio), and RFoG. On a single core of fibre (ok, lots of single cores being a passive network., but all services ACTIVE on a single core, no physical segregation). Don't get me wrong, i questioned the need for the above, sometimes segregation is good, and overkill is sometimes bad, but it was all entirely possible. And it was designed (thankfully not implemented!) Just like it's possible to swap out a line card in a GPON system, add NGPON to a service, add an extra MUX, and with only about 10 minutes of downtime per OLT you can suddenly have 10GPON services running over the NBN on the exact same fibres that are providing existing GPON services to everyone. Even on the same OLT, no need for multiples, just a new line card to activate the new NGPON services.

    Good to see this place (and the people!) haven't changed... haha ;)

    NEW FORUM ISSUES HERE PLEASE (Atomic v.π)

    Exactly! So a date would be *bloody* useful. Bit of a (massive) oversight, IMO. Ignoring the fact that an email should have been sent out to all users affected.

    So... that big banner announcement at the top of the green room regarding passwords.... When did that happen? There's no date reference on the announcement at all from what i can see... Wouldn't mind knowing when my password was compromised.

    Yep, am aware.

    NBN - Is it too expensive?

    I'm on the 2016 build list for MTM in WA... Which means, for me, FTTN via VDSL2, unless technologies change again. Knowing how old the copper is at my house, i'm going to be surprised if i get anywhere near 100mbit, probably closer to 30-50... That said, when it finally happens (probably 2019 for build completion), if i'm still at that house i'll just get it upgraded to fibre, if the cost isn't stupid high.
