Connectivity

<html><body>
The National Broadband Network’s FTTP (fibre-to-the-premises) connections are costing $4405 on average and are among the most expensive in the world, according to an industry expert.
Rod Tucker, a telecommunications expert and professor at the University of Melbourne, told the Senate committee overseeing NBN that Australia FTTP connections on average per premises was way higher than New Zealand’s $NZ2800 ($2677) and even the United States’ $US1719 ($2259), The Australian reported.
“Australia’s FTTP rollout is likely to be one of the most expensive, if not the most expensive, in the world,” he said in a question on notice tabled in the Senate.
Even new technologies were not able to reduce connection costs, Dr Tucker said.
For comparison, he said Verizon in the US had halved FTTP connection costs since the start of the rollout while in France and Spain, operator Orange had reduced connection costs by 10 per cent each year.
NBN Co, however, claims that this cost is fixed, Dr Tucker said.
In fact, many countries with high GDP per capita, like Australia, have in fact lower costs for FTTP.
An NBN spokeswoman told the Australian that the “extremely high cost of deploying FTTP to every single premise is why almost every country around the world is deploying a mixture of technologies to deliver better broadband”.
“Whilst smaller countries like Singapore may not be able to ­afford to deliver FTTP to every single premise, larger countries like the US, Canada, France, Germany, Italy and the UK and ­others are deploying a combination of ... technologies to deliver better broadband — just as we are doing at NBN.”
Adding to the controversy is recent research by the Centre for Research Excellence in the Social Determinants of Health Equity that examined the rollout of NBN technologies as of December 2016. It said "preliminary analyses suggest areas of greatest socio-economic disadvantage overlap with regions typically receiving <a href="https://www.urban.com.au/expert-insights/72012-the-nbn-and-australia-s-digital-divide" target="_blank">NBN infrastructure of poorer quality</a>".

NBN network rollout costs among the highest in the world

GUEST OBSERVATION
COVID-19 has forced us into social distancing, isolation and quarantine. These conditions are likely fostering widespread <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30460-8/fulltext">anxiety and loneliness</a> in our cities. However, they’ve also made the need for socially connected, vibrant public spaces obvious to all.
We offer four strategies for rebuilding social connectivity and emotional well-being in our cities, once restrictions are lifted.
Changing the emotional climate
Enforced distancing measures are probably changing not just our work, travel and family routines, but how we interact with others and how we feel about ourselves and our communities.
Loneliness is <a href="https://theconversation.com/loneliness-is-a-social-cancer-every-bit-as-alarming-as-cancer-itself-126741">bad for your health</a> and is likely on the rise. There is no guarantee the pandemic-driven shift towards <a href="https://theconversation.com/does-social-media-make-us-more-or-less-lonely-depends-on-how-you-use-it-128468">more digital communication</a> will compensate for the lost emotional closeness of in-person contact.
As loneliness becomes more common, it creates a change in what sociologists refer to as “<a href="https://www.researchgate.net/publication/258997923_Towards_a_Theory_of_Collective_Emotions">emotional climates</a>” – the collective feelings experienced and shared by most people within a given city or society. A “mass emotional event” like COVID-19 can dramatically alter the emotional climate. It’s so disruptive that it leads to a permanent change in everyday emotional states, expressions and social interactions.
COVID-19 has strong potential to make us not only lonelier, but more distrustful, fearful, anxious and angry. The emerging evidence of this includes: <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2020-03-16/coronavirus-is-not-a-threat-to-food-supply-experts-say/12058412">panic buying of goods</a>; abuse and stigma of “risky” carers such as <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2020-04-05/nsw-nurses-midwives-abused-during-coronavirus-pandemic/12123216">health workers</a>; and potential increases in <a href="https://www.theguardian.com/society/2020/apr/15/domestic-abuse-killings-more-than-double-amid-covid-19-lockdown">domestic violence</a> and <a href="https://www.sbs.com.au/news/insight/why-pets-are-at-risk-during-the-coronavirus-pandemic?cid=news:socialshare:twitter">animal cruelty</a>.
It has even been <a href="https://www.smh.com.au/lifestyle/life-and-relationships/we-re-grieving-collectively-finding-calm-in-a-pandemic-20200409-p54ipe">suggested</a> we are collectively processing and moving through the stages of mass grief.
It’s important to remedy negative emotional climates with strategies to reconnect communities, allay fears and better prepare us for any <a href="https://books.google.com.au/books?id=xKf_I2SYfQUC&amp;pg=PA284&amp;lpg=PA284&amp;dq=era+of+returned+pandemics+beaglehole&amp;source=bl&amp;ots=nsErrqzub6&amp;sig=ACfU3U3dlpHNJvxKsqaWrNKsL2EViHkMKw&amp;hl=en&amp;sa=X&amp;ved=2ahUKEwi90_PezeToAhUtyzgGHVx-Cs8Q6AEwCXoECAwQKQ#v=onepage&amp;q=era%20of%20returned%20pandemics%20beaglehole&amp;f=false">future shutdowns</a>. We can even aim to promote positive emotional climates and “<a href="https://www.theage.com.au/national/victoria/kindness-outbreak-keeping-people-occupied-and-entertained-20200316-p54and?fbclid=IwAR3RiXvSw29EUBNzE79CwMbBtZKvU-">kindness pandemics</a>”.
4 ways to build better communities
COVID-19 is an opportunity to build on what we know and to learn from this situation. It’s possible to promote social and emotional well-being. We suggest four key approaches for building better communities that do this.
1) Design walkable, social, flexible public spaces
Recent work-from-home practices have reduced car traffic by up to <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2020-04-11/how-coronavirus-could-forever-change-our-cities-and-suburbs/12137122">50% on arterial roads</a>. However, they have also prompted <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2020-04-11/how-coronavirus-could-forever-change-our-cities-and-suburbs/12137122">cabin fever</a> and a craving for exercise and social contact.
Cities and suburbs should be redesigned to support physical and social activity and mental health. We need a greater emphasis on <a href="https://www.smh.com.au/national/nsw/sydney-s-inner-west-gets-20m-for-cycleways-to-revitalise-open-spaces-20200421-p54lsl">cycle- and pedestrian-friendly spaces</a>. There should also be renewed focus on building walkable town centres and <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2020-04-11/how-coronavirus-could-forever-change-our-cities-and-suburbs/12137122">neighbourhood high streets</a>, rather than continuing with car-dependent suburban sprawl.
Recent examples of innovative and flexible use of space by business are inspiring. Whether cafes become corner stores, <a href="https://concreteplayground.com/sydney/food-drink/sydneys-bars-restrictions">pubs sell takeaway cocktails</a>, parks become gyms, or <a href="https://grattan.edu.au/report/social-cities/">car parks become pop-up businesses</a>, flexible use of space should become commonplace.
2) Integrate public and online spaces
Our new <a href="https://ro.uow.edu.au/lhapapers/3836/">online communication skills</a> can help us develop a better <a href="https://theconversation.com/does-social-media-make-us-more-or-less-lonely-depends-on-how-you-use-it-128468">physical-digital interface</a> for bringing people together.
Video conferencing is flexible and can enable long-distance connection and “work from home” hubs. However, social media platforms, such as Facebook, Meetup, WhatsApp or art-based apps like <a href="https://www.mirandajuly.com/somebody-2/?fbclid=IwAR2PfAyCNFei9_F14z7veslK4Lnzay_Kb4w9iPCWfQYHvRrWWlvU_KhvGwY">Somebody</a>, are useful for organising physical meetings too. These can can help with community volunteering, socialising, or simply sharing <a href="https://www.theage.com.au/national/victoria/kindness-outbreak-keeping-people-occupied-and-entertained-20200316-p54and?fbclid=IwAR3RiXvSw29EUBNzE79CwMbBtZKvU-V_p9SaGBWFkt2QTrHX_wg7OjZMs34">guerrilla-garden herbs for local cooking</a>.
A better physical-digital interface could help new jobs flourish in “interactive” creative industries that virtually connect isolated individuals. New art spaces could be established, putting connective digital infrastructure, such as audio-visual platforms, within physical spaces to help face-to-face and virtual audiences interact.
3) Provide quality housing
COVID-19 has exposed the vast variability in the quality of Australian housing. Many homes lack the space to accommodate work, study, relaxation, exercise and socialising, or spaces where people can seek <a href="https://www.wearethemighty.com/MIGHTY-SURVIVAL/covid-19-memes?rebelltitem=60#rebelltitem60">privacy and quiet</a>. Housing also varies in its access to fresh air, light, temperature control and <a href="http://www.mentalhealthpromotion.net/resources/the-built-environment-and-mental-health.pdf%20https://eprints.qut.edu.au/84990/">healthy green spaces</a>.
Designing future homes with these needs and features in mind should be a priority.
4) Build with different needs and stigma in mind
The impacts of COVID-19 will not be felt equally. Post-COVID-19 cities should take this into account.
COVID-19 has exposed the vulnerability of people <a href="https://www.economist.com/international/2020/04/12/might-the-pandemic-be-a-lifeline-for-the-rich-worlds-homeless?fbclid=IwAR2IAYqOHV7NeeH299AQySy8tUZM3JEFEPUofL18VZ9FB3IIikvAxUWM9kE">experiencing homelessness</a>. It has also greatly increased the risk of loneliness for the <a href="https://www.abs.gov.au/ausstats/abs@.nsf/Lookup/by%20Subject/2071.0%7E2016%7EMain%20Features%7ESnapshot%20of%20Australia,%202016%7E2">one in four Australians who live alone</a>. This applies particularly to older Australians with a mobility impairment.
The pandemic has also highlighted the safety risks of centralised living arrangements <a href="https://www.forbes.com/sites/andrewpulrang/2020/03/08/5-things-to-know-about-coronavirus-and-people-with-disabilities/#eef2b4d1d21f">like nursing homes</a>.
We must prioritise the creation of housing that reduces isolation and promotes social connection.

Reconnecting after coronavirus – 4 key ways cities can counter anxiety and loneliness

GUEST OBSERVER
With all of the negative press about Australia’s National Broadband Network (NBN), consumers who have the option to switch to the NBN from a working broadband connection might be forgiven for being cautious.
After the NBN is made available in an area, residents have up to 18 months to switch from their current plans to one provided on the NBN. Once it is available in an area however, residents are usually deluged with offers from various internet service providers (ISPs) about switching, making it hard to ignore. 
<h2>Moving to NBN on HFC</h2>
In my area in Western Australia, I have had HFC from Telstra for many years and so changing to the NBN does not involve a change in the underlying technology. Although some researchers have classified HFC as being an inferior technology to Fibre to the Node, it is actually capable of delivering speeds of 100 Mbps down and 40 Mbps up. Within the next one to two years HFC will be capable of 1 Gbps speeds with the roll out of DOCSIS 3.1. 
HFC connections may still suffer if ISPs do not adequately provision adequate CVC capacity on the NBN but HFC does not have the same limitations as Fibre to the Node with regard to the distance from the node. There is also a possibility that the NBN will see more homes connected to a node than was the case when Telstra ran the network. This may also impact performance.
In my case, I was consistently getting speeds of 100 Mbps for downloads but only 2 Mbps for uploads. Prior to the NBN, these speeds have been a luxury for those Australian’s who lived in areas that were services by Telstra and Optus with HFC.
Making the switch to the NBN was relatively simple but uncovered some decisions that it is worth spending time considering. If doing a conversion, some of the options aren’t made obvious by the sales team and so need to be explicitly requested.
<h2>The question of speed</h2>
Once you have decided on an ISP, there is the question of what speed of connection is available at any given residence. HFC doesn’t suffer from a slowdown based on the distance from the “node” and so speeds up to 100 Mbps are available. ISPs like Telstra however, sell plans based on download limits and at the default of 25 Mpbs. Choosing up to 100 Mbps costs another AUD 30 a month. 
It seems that for most Australians who have connected to the NBN, the default of 25 Mbps has been the most popular choice, with 53% of fixed connections being at 25 Mbps and a further 29% at the lowest tier of 12 Mbps. For the average family just watching streaming video and using social media and browsing, this is likely to be fine. It has resulted however in the overall average speed of internet connections in Australia remaining low at 10.1 Mbps.
<h2>Choice of wireless router</h2>
Another choice that doesn’t seem important at the time is the choice of wireless router that ISPs offer. Here again, the default for Telstra is a basic Sagemcom F@ST 5535. And it is basic. It doesn’t support the fastest wireless protocols used by recent smartphones and laptops, 802.11ac. The fixed cable connections from the router are also not the fastest kind. Not having the fastest wireless can make a significant difference to the overall speed of the internet connection of devices and so it is always worth upgrading. 
Some of the routers also have the ability to fail over to using 4G if the NBN connection is not available for any reason. This may be important because on the NBN, the landline phone is switched over to using the main internet connection using Voice over IP (VoIP) and not the physical connection over the old copper network. However, if the power goes out, the phone will also be unavailable even by this route.
Other than for the phone connection, any wireless router can be connected to the NBN modem. The Telstra router can then be simply used for the phone connection and its WiFi switched off. 
<h2>Making the switch</h2>
For me, and I stress the personal nature of this, the switch was fast, efficient and painless. From contacting Telstra, the wireless router was shipped within 4 days and the appointment with the NBN technician booked for a week after the order was placed. Any interaction with the Telstra NBN connection staff involved little wait times and the only negatives were some confusing emails and an order status that said the order was delayed when it wasn’t.
The NBN technician arrived and didn’t need to switch the physical box attached to the wall outside the house. It was just a question of plugging in the modem, making sure it worked, and telling NBN and Telstra to switch it all on. The technician gave me advice of avoiding being disconnected when making the switch over from the old system to the new and then left, although I had been barraging him with questions about how the rollout was going. 
Getting connected was just a question of connecting the wireless router to the NBN modem, switching it on and connecting to the wireless network. As I mentioned above, I use Apple wireless routers and so altered the configuration after things were connected.
<h2>And the results?</h2>
The download speed dropped from the Telstra non-NBN connection. During the morning, I got about 94 Mbps download. The massive difference was in the upload speed which is now about 38 Mbps. This is a huge bonus over the existing connection which gave 2 Mbps. Upload speeds are never really thought about as a problem until you realise that synchronising with services like iCloud, Google Drive and DropBox all become significantly faster with the NBN connection. 
However, in the evening, the speed dropped to between 50 - 70 Mbps download and 23 - 35 Mbps upload. This was something that didn’t happen on the Telstra non-NBN connection which was consistent even in the evenings. 
It is still early days and as more people connect in my immediate area, bandwidth may be further affected. Telstra may also ramp up the capacity so that there are not these changes in speed based on the time of day. 
<h2>Update from NBN Co</h2>
In response to the article, a spokesperson from NBN Co clarified the following points:
[1] With regard to the number of HFC connections per node:
“At present Telstra runs around 1000 premises on an HFC node sharing 1Gbps of capacity. On the nbn we will have only 650 premises per Node and once we reach full DOCSIS 3.1 we will have 10Gbps of capacity available”
[2] Regarding the speed drop I had experienced in the evenings:
“Your speed drop in the evening is almost certainly CVC related”

Things to consider when making the switch to the NBN and what to expect

GUEST OBSERVER
The National Broadband Network (NBN) is widely considered to be failing Australians, but it isn’t failing them equally.
Our research, undertaken at the Centre for Research Excellence in the Social Determinants of Health Equity, seeks to address health inequities by looking at the geographical distribution of infrastructure, including digital technology. 
Examining the rollout of NBN technologies as of December 2016, our preliminary analyses suggest areas of greatest socio-economic disadvantage overlap with regions typically receiving NBN infrastructure of poorer quality. 
<h2>Comparing NBN technology with inequality</h2>
To determine socio-economic disadvantage, we used the Australian Bureau of Statistics’s (ABS) socio-economic indexes for area (SEIFA) and its index of relative socio-economic advantage and disadvantage (IRSD)from 2011.
Across Australia, we found only 29% of areas with a SEIFA decile of one (the lowest-scoring 10% of areas) had fibre-to-the-premise (FTTP) – considered the best broadband technology solution available – or fibre-to-the-node (FTTN) connections. So far, around 71% of the NBN technology available in these areas involves inferior options, including hybrid fibre-coaxial (HFC), fixed wireless or satellite technologies.
On the other hand, 93% of areas with a SEIFA decile of 10 (the highest-scoring 10% of areas) had FTTP or FTTN.
<a href="https://www.propertyobserver.com.au/images/2017/06/21/Screen%20Shot%202017-06-22%20at%209.32.21%20AM.png" target="_blank">Click to enlarge</a>
<img src="https://www.urban.com.au/images/2017/06/21/Screen%20Shot%202017-06-22%20at%209.32.21%20AM.png" alt="">
This result tells a similar story to an early analysis by Sydney University’s Tooran Alizadeh of 60 NBN release sites that were announced in 2011. She found some of the most disadvantaged areas of Australia were not gaining equal access to the new infrastructure. 
If we look only at major cities in Australia – where the level of fibre technology is higher overall – areas with the greatest disadvantage, while exceeding similarly disadvantaged areas nationally, still received significantly less FTTP and FTTN: 65% of areas with a SEIFA decile of one had FTTP and FTTN, compared with 94% of areas with a SEIFA decile of 10. 
<a href="https://www.propertyobserver.com.au/images/2017/06/21/Screen%20Shot%202017-06-22%20at%209.33.26%20AM.png" target="_blank">Click to enlarge</a>
<img src="https://www.urban.com.au/images/2017/06/21/Screen%20Shot%202017-06-22%20at%209.33.26%20AM.png" alt="">
Of course Australia is a large, sparsely populated country, which makes the business case for rolling out fibre difficult in some regions. Nevertheless, inequitable access to NBN technology appears even when controlling for the remoteness of the location. 
If we look at outer regional Australia where fibre is less prevalent, the pattern looks worse. Only 12% of the most disadvantaged areas with a SEIFA decile of one received FTTP and FTTN, compared with 88% of the most advantaged outer regional areas with a SEIFA decile of nine.
<a href="https://www.propertyobserver.com.au/images/2017/06/21/Screen%20Shot%202017-06-22%20at%209.34.32%20AM.png" target="_blank">Click to enlarge</a>
<img src="https://www.urban.com.au/images/2017/06/21/Screen%20Shot%202017-06-22%20at%209.34.32%20AM.png" alt="">
Receiving FTTP or even FTTN may still be better than receiving HFC, fixed wireless or satellite technologies. While HFC may be able to match maximum speeds of FTTN, this is unlikely to happen during peak times when the increased number of users sharing the same data capacity will slow service considerably. And, similar to FTTN, these technologies provide fewer opportunities to upgrade capacity to meet future demand.
However, given only a limited data set was made publicly available in December 2016 by the NBN company, it is difficult to determine exactly which services are currently installed where. For example, the data set we used does not differentiate between FTTP and the lesser FTTN connection.
It also aggregates some NBN technology into an “other” category, making it impossible to distinguish between HFC and satellite service.
<a href="https://www.propertyobserver.com.au/images/2017/06/21/file-20170619-22129-15bjd9a.png" target="_blank">Click to enlarge</a>
<img src="https://www.urban.com.au/images/2017/06/21/file-20170619-22129-15bjd9a.png" alt="">
The NBN company offers a “check your address” search for its most up-to-date rollout information including technology type, but was unable to share this information with us in a single, usable data set.
A NBN spokesperson said the network was being rolled out across Australia regardless of any socio-economic mapping. 
“Determining the sequence is a complex process of weighing up factors including the location of construction resources, current service levels, existing broadband infrastructure, growth forecasts and proximity to nbn infrastructure such as the transit network,” she said in an email. “Only 8 per cent of premises in Australia are not in the fixed-line footprint.”
<h2>Internet access and social inequity</h2>
A faster internet connection is increasingly central to people’s social connections, education opportunities, employment prospects and ability to access services.
This was raised in a 2011 report by the parliamentary Standing Committee on Infrastructure and Communications. It emphasised the potential role of the NBN in enhancing greater equity in digital access to services in regional and rural areas. 
"The Committee heard that, due to the ‘digital divide’, many of the Australians who could benefit the most from broadband currently have the lowest levels of online participation … The extent of accompanying measures implemented by governments will determine whether the NBN narrows or widens this digital divide."
Previous research has also found that people from lower socioeconomic groups are already restricted in their use of digital information and communication technologies. This can limit their access to a range of social determinants of health. 
When populations already facing disadvantage receive poorer quality digital infrastructure, those with the greatest need will continue to slip farther behind. 
Equity must be at the forefront of the NBN company’s considerations as it continues to roll out across Australia. Further entrenching social inequities through digital infrastructure is not the NBN anyone dreamed of.
