Just because a backbone can carry heavy data rates does not mean that it is avaioable for the end points. Fibre depending on it's quality can carry a lot of information. The trick is the physics on how to transmit encoded signals that maximise the use of fibre. We have moved to have mulitple channels/frequencies carrying lot's of information to a more complex mechanism encoding the light signals to carry more information. This is generally between large routers. You can not offer end points the speed of the backbone, that will not work.1Mbps is the current rate, 10mbps is not far away and 100Mbps will not take that long and the new speed just requires new gear at either end, the fibre can carry terabits per second
Now you are speculating. 12 mbps is definitely fast enough for TV. Improvements in data compression will make it last even longer.12mbps is fast enough? For todays applications maybe altho I bet that it is starting to not be enough but stuff like TV over IP will need more.
With the move towards thin clients (dumb screens) the processing power is in the network. Like cloud comuting. The need for large uploads is diminishing not growing. As i said, if you truelly need large upload speeds you need a different archecture than pushing huge data into the network from an office or home.An advantage of the FTTP is that upload speeds can be a huge percent as fast as can download speeds, unlike ADSL etc.
I agree. Also fibre needs points wired to every connection point. The trick here is you do not need to have fibre for the last mile. You use fibre to a common point in the area and then wireless for the last mile or so. this would save huge amounts of cash because that is where a majority of the cost is. So i argue for the compromise. Fibre to carry the backbone... wireless for the last mile for most people where fibre to the door is prohibitively expense. Where this does not work, then a network of wireless routers or satelite as the last draw.Wireless, no matter how advanced still needs lots and lots of transmission points which I doubt would be built and they would still be wired back—the NBN could provide that back wiring.
