Internet Use

GUEST OBSERVATION
There’s little doubt the information technology revolution has improved our lives. But unless we find a new form of electronic technology that uses less energy, computing will become limited by an “energy crunch” within decades.
Even the most common events in our daily life – making a phone call, sending a text message or checking an email – use computing power. Some tasks, such as watching videos, require a lot of processing, and so consume a lot of energy.
Because of the energy required to power the massive, factory-sized data centres and networks that connect the internet, computing already <a href="https://www.sciencedirect.com/science/article/pii/S2214629618301051" target="_blank">consumes 5% of global electricity</a>. And that electricity load is doubling every decade.
Fortunately, there are new areas of physics that offer promise for massively reduced energy use.
The end of Moore’s Law
Humans have an insatiable demand for computing power.
Smartphones, for example, have become one of the most important devices of our lives. We use them to access weather forecasts, plot the best route through traffic, and watch the latest season of our favourite series.
And we expect our smartphones to become even more powerful in the future. We want them to translate language in real time, transport us to new locations via virtual reality, and connect us to the “Internet of Things”.
The computing required to make these features a reality doesn’t actually happen in our phones. Rather it’s enabled by a huge network of mobile phone towers, Wi-Fi networks and massive, factory-sized data centres known as “server farms”.
For the past five decades, our increasing need for computing was largely satisfied by incremental improvements in conventional, silicon-based computing technology: ever-smaller, ever-faster, ever-more efficient chips. We refer to this constant shrinking of silicon components as “Moore’s Law”.
Moore’s law is named after Intel co-founder Gordon Moore, who observed <a href="https://www.investopedia.com/terms/m/mooreslaw.asp" target="_blank">that</a> "the number of transistors on a chip doubles every year while the costs are halved".
But as we hit limits of basic physics and economy, Moore’s law is winding down. We could see the end of efficiency gains using current, silicon-based technology as soon as 2020.
Our growing demand for computing capacity must be met with gains in computing efficiency, otherwise the information revolution will slow down from power hunger.
Achieving this sustainably means finding a new technology that uses less energy in computation. This is referred to as a “beyond CMOS” solution, in that it requires a radical shift from the silicon-based CMOS (complementary metal–oxide–semiconductor) technology that has been the backbone of computing for the last five decades.
Why does computing consume energy at all?
Processing of information takes energy. When using an electronic device to watch TV, listen to music, model the weather or any other task that requires information to be processed, there are millions and millions of binary calculations going on in the background. There are zeros and ones being flipped, added, multiplied and divided at incredible speeds.
The fact that a microprocessor can perform these calculations billions of times a second is exactly why computers have revolutionised our lives.
But information processing doesn’t come for free. Physics tells us that every time we perform an operation – for example, adding two numbers together – we must pay an energy cost.
And the cost of doing calculations isn’t the only energy cost of running a computer. In fact, anyone who has ever used a laptop balanced on their legs will attest that most of the energy gets converted to heat. This heat comes from the resistance that electricity meets when it flows through a material.
It is this wasted energy due to electrical resistance that researchers are hoping to minimise.
Recent advances point to solutions
Running a computer will always consume some energy, but we are a long way (several orders of magnitude) away from computers that are as efficient as the laws of physics allow. Several recent advances give us hope for entirely new solutions to this problem via new materials and new concepts.
Very thin materials
One recent step forward in physics and materials science is being able to build and control materials that are only one or a few atoms thick. When a material forms such a thin layer, and the movement of electrons is confined to this sheet, it is possible for electricity to flow without resistance.
There are a range of different materials that show this property (or might show it). Our research at the ARC Centre for Future Low-Energy Electronics Technologies (<a href="http://www.fleet.org.au/" target="_blank">FLEET</a>) is focused on studying these materials.
The study of shapes
There is also an exciting conceptual leap that helps us understand this property of electricity flow without resistance.
This idea comes from a branch of mathematics called “topology”. Topology tells us how to compare shapes: what makes them the same and what makes them different.
Image a coffee cup made from soft clay. You could slowly squish and squeeze this shape until it looks like a donut. The hole in the handle of the cup becomes the hole in the donut, and the rest of the cup gets squished to form part of the donut.
Topology tells us that donuts and coffee cups are equivalent because we can deform one into the other without cutting it, poking holes in it, or joining pieces together.
It turns out that the strange rules that govern how electricity flows in thin layers can be understood in terms of topology. This insight was the focus of the <a href="https://www.nobelprize.org/prizes/physics/2016/press-release/" target="_blank">2016 Nobel Prize</a>, and it’s driving an enormous amount of current research in physics and engineering.
<iframe src="https://www.youtube.com/embed/LV4uFHqdio4?wmode=transparent&amp;start=0" frameborder="0" width="440" height="260"></iframe>
We want to take advantage of these new materials and insights to develop the next generation of low-energy electronics devices, which will be based on topological science to allow electricity to flow with minimal resistance.
This work creates the possibility of a sustainable continuation of the IT revolution – without the huge energy cost.<img src="https://counter.theconversation.com/content/106060/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

Computing faces an energy crunch unless new technologies are found

<html><body>
GUEST OBSERVER
Most Australians will be forced to move onto the NBN within 18 months of it being switched on in their area, and that means navigating what can be confusing new contracts.
So, what are your rights regarding landline and internet connections?
Landlines
Many consumers can and do manage without a landline. But particularly for those without a reliable mobile service, a landline can be essential. It is included in many phone and internet “bundles” offered by internet service providers.
Standard telephone services (primarily landline services) are subject to a Customer Service Guarantee enshrined in law under the Telecommunications Act 1997.
This means that standards apply to common services such as connection of a phone line, repairs of that line and attending appointments on time. The provider will have to pay compensation to the customer if the Customer Service Guarantee standards are not met.
Despite this, some providers suggest a customer waive his or her customer service guarantee rights. There are safeguards for this waiver to be effective, primarily in that the provider must explain the nature of the rights to the customer before asking for the waiver.
The idea behind allowing providers to request a waiver of the Customer Service Guarantee is that it will allow customers to obtain cheaper services than would otherwise be the case. However, we might question the integrity of the consent typically given to such waivers, given consumers generally don’t read contracts and may have little understanding of the value of the Customer Service Guarantee or the likelihood of having to claim under it.
In any event, providers cannot ask for a waiver for Universal Service Obligations, which ensure accessible services for all customers, including those with a disability and those who live in remote areas.
Internet
The Customer Service Guarantee does not apply to internet connections – although the Australian Communications Consumer Action Network has argued that it should.
So there are no statutory obligations for internet providers, or NBN Co, to connect customers within a particular time frame or respond promptly to complaints.
The main safeguard for customers for internet services is in the Australian Consumer Law (ACL).
If an internet service provider promises a particular broadband speed and does not provide that speed, the provider may have engaged in misleading conduct contrary to the ACL. Damages and even penalty payments could be awarded against it. And fine print qualifications to the headline statement about internet speeds will not necessary protect the provider.
In addition, the Consumer Guarantees under the ACL (not to be confused with the Customer Service Guarantee under the Telecommunications Act) ensure that any equipment provided with an internet service must be of acceptable quality, and services be provided with due care and skill.
If these standards are not met, the consumer has a right to certain remedies under the ACL and damages for losses that result from the failure. These rights should go some way to protecting telecommunications consumers, although of course they do not directly guarantee that the provider will arrive on time for a scheduled appointment.
<img src="https://counter.theconversation.com/content/85904/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">So while you may wish to charge your internet service provider for not turning up to an installation appointment, you wouldn’t get far under current Australian law.

GUEST OBSERVER
Internet and broadband connectivity are the foundation of the networked economy.
But to ensure the benefits of the networked economy are evenly distributed, the Australian government needs to ensure access to the internet to encourage and support innovation. 
A recent report from SGS Economics and Planning highlights a widening gap between the economic workhorses of Sydney and Melbourne and regional Australia. 
All of the key sectors experiencing growth depend upon the networked economy. The emerging economic environment is leveraging the rapid rise in real-time connectivity between people, businesses, devices and systems. 
The result is the digitisation of many transactions and growing importance of data. The Productivity Commission’s draft report on data use and availability highlights the need for clear thinking to make this transformation fair for all stakeholders. 
When the telephone network was rolled out, this was enshrined in the Universal Service Obligation (USO), a framework to provide a basic level of connectivity. 
A key question is whether the USO principle of connectivity is sufficient for the emerging Australian networked economy. The answer is very clearly “yes”. But urgent attention is required to deliver fair, equitable and cost-effective access to broadband and internet connectivity to enable economic development in the cities and the regions.
To be digitally inclusive, Australia needs to overcome the digital divide. There is a significant divergence in the nature and availability of communication and internet services for regional Australia. 
nbn co’s broadband index clearly highlights the widening gap between metropolitan areas and regional areas not serviced by an NBN plan. 
The reaction from regional Australia has been very clear. A new Regional, Rural and Remote Communications Coalition between the Australian Customer Action Network (ACCAN), the National Farmers’ Federation, the Country Women’s Association of NSW, the Isolated Children’s Parents’ Association and AgForce Queensland is advocating for better access in five key areas. 
This sentiment is supported by Internet Australia’s submission to the Productivity Commission. The group, which includes the Melbourne Networked Society Institute, argues for important changes to ensure connectivity. 
So, what is being advocated? 
Universal service obligation
Australians need a new USO provision that incorporates both voice and data connectivity to ensure internet access is guaranteed to all citizens. 
This will address digital cohesion and ensure everyone can participate in the growing networked economy. nbn co should be allowed to provide retail services to customers where there is only one commercial provider to encourage competition and access. 
Service guarantees and reliability
As broadband deployment and uptake increase, service offerings need to provide better and more transparent guarantees to customers. The network should have better reliability measures and offer services with certain quality of customer experience. 
Countries such as the UK already provide a reporting framework to make ISPs accountable for their performance. This includes the speed of connection customers can expect to receive during peak hours. 
Such requirements support competition by focusing service providers on differentiation while lifting performance. This creates incentives for investing in resources to address emerging issues such as the effect of backhaul networks on broadband performance.
Mobile network access
Mobile network technology is critical for the economic activities of regional Australia. Ensuring that network coverage is expanded to everyone also promotes social cohesion. 
Regional Australia needs network coverage to take advantage of emerging opportunities from technologies such as the internet of things. This will enable significant productivity gains in industry sectors such as mining and resources, agriculture and food processing, as well as professional services. 
A government commitment to mobile network coverage is a key step to guarantee such investments and make it attractive for network operators to build the network. 
Fair and equitable broadband access
nbn co’s SkyMuster satellite services (the second satellite will be available in 2017) and its fixed wireless services will face significant demand, which presents issues for fair and equitable access. This will create difficulties in matching the needs of different stakeholders across regional Australia. 
On the one hand, new services such as internet access on (Qantas and Virgin) flights could potentially add congestion to satellite services, depending on the access and allocation of resources. 
Alternatively, new business opportunities enabled by the internet of things and the digital economy might demand low-latency connectivity, which a satellite service cannot provide in regional Australia. 
Therefore, to realise the potential gains, nbn co needs to support investment in development and adoption of new broadband technologies that can provide greater bandwidth, or lower latency, services cost-effectively to regional Australia.
Digital capacity building
Through the government’s digital transformation agenda, it is imperative to ensure regional Australia is empowered through programs focused on digital capacity building. 
This should include skills development, assistance to access new technologies and support for businesses and consumers. As the data becomes a key economic enabler, data skills and platforms for regional Australia will also become a major priority.
While the case for lifting the economic and social participation of regional Australia in the emerging networked economy is very strong, will the policy framework evolve to make it a priority? The bush is crying out for equitable access to broadband.

Regional Australia is crying out for equitable access to broadband

<html><body>
GUEST OBSERVERS
Is the rollout for Australia’s National Broadband Network (NBN) on track? Are we employing the right technology for the job? Will the NBN be fast enough to handle future demands?
The Senate Select Committee on the National Broadband Network recently asked five of Australia’s leading academic experts to give their views on the state of the NBN.
Here, each of the experts gives a summary of their views as they presented them to the Committee, raising concerns about the current technology and suggesting there might be ways to improve the NBN rollout using new approaches being adopted overseas.
David Glance, University of Western Australia
The Senate Committee was brought up-to-date with contemporary answers to these questions. It was given examples of companies and countries that thought fibre to the node (FTTN) was an adequate implementation strategy, but have since changed to a fibre to the premises (FTTP) approach.
In the US for example, AT&amp;T last year abandoned fibre to the node and has switched to deploying fibre to the premises because of the speed and capacity limitations, and because 1 Gigabit per second (1 Gbps) is the “new normal”.
AT&amp;T is also now certain that 25 Mbps will not be adequate for most people, and in fact, won’t be what most people actually want to deploy in their homes or businesses. Households are already consuming multiple simultaneous media streams at whatever definition their network will support. Business, especially in an online innovation-led economy, is increasingly coming to rely on the presence of ultra-fast broadband.
Costs and technologies that make up those costs have also changed. In Australia, since the decision was made to switch to a fibre to the node implementation of the NBN, costs of implementing other solutions, including Fibre to the Pavement (Sidewalk) have come down. Technology solutions like G.Fast allow short lengths of copper to be used to a home and still deliver 1 Gbps speed.
With technology, especially in the time frame of the construction of the NBN, the rationale for a particular approach will change. In the case of the NBN, most of the answers to the usual questions have indeed changed, and continuing with a fibre to the node approach no longer makes any sense.
Mark A. Gregory, RMIT University
The NBN is a nation building project that has been hijacked by politics. As a result, the obsolete fibre to the node technology is being rolled to a large number of Australians.
The government should accept the weight of international evidence and move back to fibre to the premises (FTTP). There is an urgent need for a 20 to 30 year life-cycle costing analysis to be completed to provide an engineering cost benefit justification for the NBN technologies to be used in the rollout.
There is a need for a broad panel to be formed that includes academics, industry, consumer representatives and government to discuss the future of the NBN beyond 2020.
It is time for Australia to adopt a “universal access” regime, where everyone can connect reliably to digital services, including health and education and other government services, at all times. This is especially for the socially and economically disadvantaged, including the homeless and itinerant, to be provided with the means to access digital services.
For this reason, nbn Co should rollout a national wholesale Wi-Fi network to facilitate companies and local government offering free Wi-Fi similar to what is happening now through Telstra Air.
 
Rod Tucker, University of Melbourne
Since the days of dial-up modems, there has been a relentless growth in demand for higher broadband speeds. But the 2014 Vertigan report underestimated Australia’s future broadband needs by a factor of ten. Vertigan supported the Coalition’s game-changing shift from fibre to the premises (FTTP) to fibre to the node (FTTN).
Since Vertigan, a lot has happened in the broadband world. For example, the major US telco AT&amp;T has switched from FTTN to FTTP, arguing that demand is growing for speeds that FTTN cannot deliver. And rollouts of FTTP are accelerating in many countries. Australia is rapidly being left behind.
All of this points in one direction: Australia’s FTTN network will be obsolete by the time it is rolled out and will not be able to deliver the speeds that will be needed in the future.
Unlike FTTP and other technologies such as fibre to the distribution point (FTTdP), FTTN will be expensive to upgrade and a future owner of the FTTN network may not bother. Every way you look at it, FTTN is a bad idea.
The notion FTTP is much more expensive than FTTN turns out to be incorrect. The cost of rolling out FTTN is often understated and the cost of rolling out FTTP is overstated. New lower-cost FTTP construction techniques and cost increases for FTTN have changed the equation.
While public attention has generally focused on the fixed network in urban areas, people in rural and remote areas will use NBN’s satellites. Qantas also plans to use nbn’s satellites to provide video entertainment on its flights, sapping bandwidth from people on the ground. A third satellite will alleviate this problem.
My advice to the Senate Select Committee on the NBN is that the FTTN rollout should be abandoned before it is too late, and replaced with FTTP.
Arthur Lowery, Monash University
I have been in telecommunications for over 35 years now, and co-founded VPIsystems, a company that develops software tools for optimising and rolling-out telecommunications systems using multiple technologies, such as national broadband connectivity.
The goal of the NBN is laudable: to provide decent connectivity to everybody in Australia. I’m interested, as a taxpayer, in how this can be done in a cost efficient manner. One of my points is that a rollout is a longish-term endeavour, and maybe it should provide long-term employment for its skilled-up workforce.
Thus, when designing the rollout, a staged approach should be used. Because civil engineering is a large part of the cost, it is prudent to defer decommissioning existing infrastructure close to dwellings (which can support &gt; 1 Gbit/s, as it is short and not shared), and concentrate on the real bottlenecks nearer the exchanges.
This means “fibre-to-the-fence” (G.fast). The fact that many period Australian homes are being rapidly replaced also makes FTTP question somewhat academic. Of course, once fibre is at the gate, it’s relatively easy extend to any building in the future, if needs be.
Thas Nirmalathas, University of Melbourne
The rapid proliferation of connected devices is transforming connectivity between people, places and things and creating a networked society. This presents many opportunities for citizens, businesses, and governments through the advancement and use of connectivity.
The NBN presents Australia with an opportunity to provide the critical infrastructure for the networked society. It remains the essential launch pad for transformation of key industry sectors, for a data-driven economy, and for delivering greater social equity across the Australian society.
Global rankings of internet connectivity and speed show that Australia needs to improve its standing or risk being left behind by the current wave of innovation. Australia falls short particular on broadband subscriptions and faces a widening gap between peak and average speed of internet connections.
The NBN rollout provides an opportunity for Australia to increase bandwidth and capacity to support innovation. However, in order to meet growing demands to enable innovation the NBN rollout must improve.
The actual rollout rates is falling short of the original targets promised under the NBN. Despite a change in the technology mix and revised network architectural options recommended through the strategic reports, NBN deployment remains slow across both new and existing sites.
The NBN should plan for a third satellite without waiting for demand saturation. Machine-to-machine traffic arising from connected devices across many key sectors of relevance to regional Australia will demand cost-effective wireless access using satellite or other wireless alternatives such as those that could take advantage of optical fibre networks to provide improved wireless coverage and access.

Property 101: The state of the NBN

<html><body>
GUEST OBSERVER
The digital divide continues to narrow in Australia but important divisions persist, and there are clear disparities between different groups in their use of the internet.
It’s a pattern that’s been apparent for some time and it has been confirmed by an analysis of data on the household use of technology released last week by the Australian Bureau of Statistics. 
First, the good news. The research found 85 percent of Australians aged 15 and older were internet users and that 86 percent of Australian households had internet access in 2014-15 (up from 83 percent two years previous and 67 percent in 2007-08).
The digital divide 
The kicker in these figures is that as more and more Australians are online, the disadvantage of being offline grows. So as the divide narrrows, it gets deeper.
Meanwhile, teachers assume their students have unrestricted access to the internet and set homework accordingly; businesses assume their customers are internet users and shape their offerings online; and governments shift resources to digital provision of information and opportunities to interact. 
But household access to the internet is not spread evenly across Australian states and territories. At one end of the scale, 94 percent of ACT households enjoy an internet connection while at the other, only 82 percent of Tasmanian and South Australian households have access. 
Those living in major cities are more likely to have access than those in rural and remote Australia; 88 percent of households in our major cities have access. This falls to 82% for those living inner regional and 79 percent for those in outer regional and remote, or very remote, areas. 
While two thirds of low-income households have access, 98 percent of the highest-income households have an internet connection. And it’s not just access that is affected by income. 
Of the lowest-income households, 44 percent have a tablet in the home, compared to 76% of the highest-income households. The mean number of devices used to access the internet in the lowest-income households is four compared to seven in the highest. 
This is important because these devices enable individuals in the household to access the internet simultaneously. Homework can be done while someone else plays games while that night’s cook looks up recipes online.
Education counts
The more highly educated you are, the more likely you are to be an internet user; 96 percent of those with a bachelor degree or higher use the internet. As educational attainment falls, this proportion decreases, down to 77 percent for those with Year 12 or below. 
Internet use by employed Australians is 93 percent; for unemployed only 70 percent. 
Age is still a key factor in internet use. Just over a half of Australians aged 65 or over use the internet while the corresponding figure of those aged 15-17 is 98.6 percent. The big drop-off in use is between those aged 55-64 (81 percent) and those in the oldest age group.
There are indications that older Australians who do use the internet are not deriving the benefits of younger users. Surprisingly, internet users aged 25-34 are twice as likely as those aged 65 or more to access health services online (32 percent to 16 percent). 
The story is the same for regional and remote Australia. The further you get from physical health services, the less likely you are to use the internet to access online health services.
This pattern is repeated for formal education online. Of internet users living in a major city, 27 percent accessed formal education online compared to 21 percent living inner regional, 20 percent in outer regional and 17 percent who are remote or very remote areas. 
Working from home
Using the internet to work from home is strongly related to income. While just under a third of employed persons living in a low-income household worked from home via the internet, 62 percent of those in the highest-income households teleworked. 
The regional pattern was also interesting. Those living in major cities or in rural and remote Australia were equally likely to telework (46 percent) compared to 38 percent living in inner regional Australia and 35 percent in outer regional Australia. 
Addressing the digital divide and fostering digital inclusion remains a challenging and important public policy issue in Australia. The Go Digi Project, a collaboration between Infoxchange and Australia Post, have designated 2016 the National Year of Digital Inclusion.
Telstra along with partners the Swinburne Institute and the Centre for Social Impact are developing the Australian Digital Inclusion Index to be launched later this year. This is an attempt to better understand who is not engaging online and how that might be remedied.
So there is a lot happening in this space.
As more and more resources shift online and connectivity becomes the norm for most Australians, the disadvantage faced by those not online or those with limited access, increases. And as faster broadband is rolled out via the national broadband network, the relative disadvantage of those on more modest connections will increase.
Just as importantly, building the digital capacity of disadvantaged Australians to enable them to take full advantage of online resources remains a critical issue. We must ensure that those with the most to gain from the digital revolution are able to fully engage with the online world.
Australia's connection to the internet continues to grow but there are still 1.3 million households not online.
