(But not before you get your wireless, I'm guessing...)
Maybe in thirty years when that same fibre infrastructure is delivering gigabits of bandwidth, you might understand the point.
Well actually that is currently being achieved with 5G wireless as of March 2015. So perhaps the question may become - will the NBN be finished before it is obsolete?
This is a good explanation:
What is 5G? 5G vs 4G and the future of mobile networks
What is 5G?
5G is a term used to describe the forthcoming fifth generation of mobile network technology.
Right now, it doesn't signify any particular type of technology. While 4G has become synonymous with LTE, there's been no publicly agreed upon standard for 5G networks. However, a couple of likely technologies are emerging.
The main quality of 5G networks compared to 4G will be speed. It's going to be many times quicker than what we have now, and by quite a way.
How fast is 5G?
Estimates have varied over recent years, but some of the industry's established players can give us an idea of where 5G's at.
We've actually seen claimed speeds of 7.5Gbps from
Samsung and 10Gbps from Nokia (these days quite the network infrastructure specialist), while this time last year the
University of Surrey managed to obtain a staggering 1Tbps - the same capacity as fibre optics. For a wireless network connection. Mental.
However, all of these tests were conducted under laboratory conditions. What we need in estimating the final speed of a 5G network is a practical field test.
Back in October
we reported on just such tests conducted by China's Huawei and Japan's NTT Docomo network. They had managed to hit peak data speeds of 3.6Gbps using a sub-6GHz band.
Compare that to the 300Mbit/s currently offered by EE's LTE-A network, and you'll see that
we're talking about a 12-fold speed increase over 4G here.
A realistic, nicely rounded final figure for
5G speeds, then, could be
in the region of 10Gbps.
How fast is 5G? Low latency, high capacity
Besides raw speed, the other main benefits of 5G will be
low latency and high capacity.
Low latency means that not only will download and upload speeds be fast, but the response times for starting those data transfers will be similarly snappy. There'll be less of a pause between pressing play on Netflix and that crisp 4K content starting to stream to your phone, in other words.
The other benefit relates to the biggest issue with current mobile network standards - a critical lack of bandwidth. The radio frequencies that our 3G and 4G networks operate on are overcrowded to say the least.
With more and more people and devices set to be connected over the next five years or so - 5G will likely be the network that has to handle the dawn of driverless cars - this will be a critical problem before too long. Whatever technology 5G employs, expect it to address this either through an all new spectrum, or through smarter use of the existing spectrum (only assigning the amount that's needed for each task).
[h=3]Why do we need it?[/h] One of the main benefits of 5G technology over 4G will not be its speed of delivery – which admittedly
could be between 10Gbps and 100Gbps – but the latency. At present, 4G is capable of between 40ms and 60ms, which is low-latency but not enough to provide real-time response.
In years past, mobile data technologies were built around hardware, while 5G will be software driven. Software can be updated easily, hardware less so.
