wolster Posted May 14, 2013 Posted May 14, 2013 Will that make the NBN redundant before it is even finished? The NBN rollout is expected to take 10 years. The 5G technology is expected to be available in 2020.
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 Will that make the NBN redundant before it is even finished? No, wireless services need to keep up within at least an order of magnitude of fixed services for ubiquitous computing.... by next decade there will be fixed services in the 10s or 100s of gigabits. Wireless also has unavoidable latency, and likely capacity issues..... it is a very very long road to travel before we will not need wires in the ground. 2
Catostylus Posted May 14, 2013 Posted May 14, 2013 When radio has the bandwidth of glass fibre, yes. Don't hold your breath. 2
antman70 Posted May 14, 2013 Posted May 14, 2013 Will that make the NBN redundant before it is even finished?The NBN rollout is expected to take 10 years. The 5G technology is expected to be available in 2020. Fibre is already capable of terabit speeds, so no. As anyone knows mobile wireless even in 4g form suffers terribly from congestion, and service providers are only able to offer low quotas of data. Even the Libs aren't saying that wireless is the future anymore. You must note that the NBN is to cover the majority of the landmass with LTE wireless in it's current plan, although that is fixed, not mobile, making it much easier to guarantee minimum speeds.
Upfront Posted May 14, 2013 Posted May 14, 2013 When radio has the bandwidth of glass fibre, yes. Don't hold your breath. Exactly. The actual fibre hasn't changed much in the last 10 years. However the Rx Tx technology has... Massively. We are restricted by the technology at the ends of the fibre. Not by the fibre itself.
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 When radio has the bandwidth of glass fibre, yes. Well, that's Samsungs point, they're keeping radio speeds up (within an order of magnitude) with wired... Anything less than that out of wireless would be problematic for future network convergence IMHO.
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 Exactly. The actual fibre hasn't changed much in the last 10 years. However the Rx Tx technology has... Massively. We are restricted by the technology at the ends of the fibre. Not by the fibre itself. You could use the same logic for the air ;-) 1
Upfront Posted May 14, 2013 Posted May 14, 2013 You could use the same logic for the air ;-) True! But if they are only talking 1gig in 10 years, i believe fibre will come out on top. Reliability is also a concern.
SteveC Posted May 14, 2013 Posted May 14, 2013 Wireless will be the way of the future. Agreed, based purely on the great scientific method called "gut feel".
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 True! But if they are only talking 1gig in 10 years, i believe fibre will come out on top. Reliability is also a concern. The 'mistake' IMHO is to think of this in terms of "fibre will come out on top" (or vice-versa). 1 gig wireless in 10 years is going to mean it is approximately an order of magnitude behind wired. Similar to today. Note the "5G" technology in the OP is also long range.... short range wireless will be (and already is now) much faster. An open wholesale wired network will allow us to take advantage of future wireless opportunities. The future will be wireless ... but it will be the wires to our building which allow that to develop. If the future if "fibreless" as well as "wireless" it is a very very long way away.
SteveC Posted May 14, 2013 Posted May 14, 2013 (edited) If the future is "fibreless" we will all be very clogged up! Edited May 14, 2013 by SteveC 2
gamve Posted May 14, 2013 Posted May 14, 2013 Ah Who cares, If your not living in a labour marginal seat area your unlikely to see the NBN for another 10 years anyway.
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 Ah Who cares, If your not living in a labour marginal seat area your unlikely to see the NBN for another 10 years anyway. 10 year plan/build for large infrastructure projects is nothing unusual. I'm honestly not a "labor guy" .... but I find the political cynicism depressing. 1
firefly0071 Posted May 14, 2013 Posted May 14, 2013 10 year plan/build for large infrastructure projects is nothing unusual. I'm honestly not a "labor guy" .... but I find the political cynicism depressing. Snowy Mountain Hydro Scheme took 17 years.

Basically to get the speeds you need to use high frequencies, which means it won't be good unless you get line of sight. Like a microwave link.
LogicprObe Posted May 14, 2013 Posted May 14, 2013 Snowy Mountain Hydro Scheme took 17 years. And it's still the only viable electricity storage facility we have. They should build another one on Cape York.
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 The key to building faster networks, especially indoors, lies in coming up with better ways of putting a larger number of smaller base stations closer to users, according to Zander.
avalon Posted May 14, 2013 Posted May 14, 2013 Ah Who cares, If your not living in a labour marginal seat area your unlikely to see the NBN for another 10 years anyway. I'd rather wait 10 years for a solution, as opposed to 10 years for........ nothing
Fangzie Posted May 14, 2013 Posted May 14, 2013 http://www.theregister.co.uk/2013/05/13/samsung_fast_5g_interface/'>2km range and requires 64 antennas...and 4g already eats battery life. I imagine this will only be worse. IMO there is more of a technical demonstration. In other news, apparently there's research showing fibre can http://www.theregister.co.uk/2013/05/13/fibre_system_xpm_noise_elimination/'>double it's current capacity 1
davewantsmoore Posted May 14, 2013 Posted May 14, 2013 fibre can double it's current capacity Fibre can already carry terabits (1000's of gigabits) depending on how you squint at it (ie. under controlled conditions so far). ZTE and BT have both demonstrated 10 gigabits in the field over the same platform our NBN uses. 100gbps is not far away apparently. ... but now I actually read what you're link is about (sorry) ... the above is just more waffle from me ;-) 1
Catostylus Posted May 14, 2013 Posted May 14, 2013 http://www.arnnet.com.au/article/461691/new_samsung_tech_could_pave_way_5g_2020/ Some decent analysis of the announcement.

Janjuggler Posted May 15, 2013 Posted May 15, 2013 (edited) it is a very very long road to travel before we will not need wires in the ground. Just remember what happened to the 'Krell' .... JJ Edited May 15, 2013 by Janjuc
