Wireless Broadband for Regional Australia

Gabrielle Chan reports in "NBN trounced by regional offering from locals with an eye for enterprise" (The Guardian, 16 December 2013), about wireless broadband being offered in the town of Harden in New South Wales.

South Western Wireless Communications is offering broadband from $19.95 a month. But the customer has to purchase the Customer-premises equipment (CPE) and it is not clear what frequencies (licensed or unlicensed) are being used.

I get a mention in the article with my likening the of ALP and Coalition broadband proposals as being like the choice between a Lexus and a 10-year-old Camry and suggesting what younger customers want is wireless broadband.

The distinction between fixed wireless and mobile broadband is now largely one of business model, rather than technology. Ericsson were contracted by NBN Co. to provide a 4G / LTE TDD for fixed wireless rural broadband. The base stations and protocols used are essentially the same as for mobile broadband. The difference is that the customer receives the service via an antenna fixed to their home or business, rather than via a mobile device.

Both ALP and Collation broadband proposals have aimed at fixed location home and small business users. Also these have assumed a high density of new users served by new fibre into each home or terminated at new equipment cabinets in each street connecting the last few hundred metres of copper cable.

The major cost with FTTP is running the cable from street to the home, with FTTN, is installing new optical cabinets  in the street and reconnecting all the copper cables to it. However, an alternative would be to install the optical fibre in the street and then only connecting customers as they require a service. For FTTN, this would require rugged miniature waterproof optical modems, which could be installed in existing pits and cabinets. When a customer ordered a service, the technician would open the pit in the street outside the house and place an optical modem in it. This would be plugged into a fibre cable and power. Copper cable can be used for up to 1 GBPS, but limited to a distance of about 100 m. So each modem need only be designed to provide service to about eight to sixteen homes.

If the customer wanted FTTH, this would require a cable to be run though the existing conduit, or more likely, a new trench and conduit laid, at the householder's expense.

NBN Providing Wireless for Regional Areas

In "What reporting of the Brunswick NBN survey didn’t tell you" (Commsday, 5 March 2013), Geoff Long looks at a study of early NBN first-release sites carried out by Melbourne and Swinburne Universities (Broadbanding Brunswick: High-speed Broadband and Household Media Ecologies: A Report on Household Take-up and Adoption of the National Broadband Network in a First Release Site, Dr Bjorn Nansen, Dr Michael Arnold, Dr Rowan Wilken, Dr Martin Gibbs, Australian Communications Consumer Action Network, 2013). While the researchers study concentrated on take-up of the NBN Long suggests there should be more research on why 20% of households have no Internet access at all, which is a good question. However, it was not clear to me from the study report if households where residents had one or more  smart phones or tablet computers with broadband wireless built in where counted as connected. If not, then the number of connected households would be greatly under-reported. The popularity of wireless devices might make the concept of "household" connection largely irrelevant, much as mobile phones has lessened the need for a home fixed telephone lines. Previously the number of telephone lines per 1,000 population was used as a measure of the communications access of a country, but this is now largely irrelivant.

 Long also suggests that the study shows that there is no urgency for urban areas to upgrade to fibre. This seems a reasonable conclusion: in urban areas which have good access to Internet via ADSL or cable, this is not a compelling case for fibre. In fact the latest take-up rates for NBN nationally show that of the 34,500 subscribers, 70% are via satellite or terrestrial wireless in regional and remoe areas, with fibre in urban areas being the minority. Also the issue of take-up in the city is not really an issue as the NBN will have an effective fixed line monopoly: the plan is to eventually remove the copper cable, so that if you want a fixed line it will have to be NBN fibre.

Multi-carrier Internet for ABC Classic FM Live Concerts

ABC Classic FM was unable to broadcast the "A Hundred Golden Autumns" concert from Canberra today, due to failure of an ISDN link between Canberra and Sydney. However, the concert was in Llewellyn Hall, which is on the campus of the Australian National University, which has a very high speed fibre optic link. The ABC could plug their router into the university network, so that could be used if the ISDN link failed. They could also have a wireless Internet connection via one of the mobile carriers, in case both wired links were lost. No special programming or configuration is needed for this, as the Internet is designed to route around failed links. The ABC just needs about $200 of extra equipment.

George Bray Showing the Use of Broadband Across Australia

Digital video maker George Bray has set off around Australia to highlight the benefits of high speed broadband with The Broadband Show and is looking for sponsors.

Ten years ago George set out on the Tech Trek. In a motor-home filled with the the latest computer and telecommunications equipment, sponsored by the industry, he demonstrated the use of the Internet to regional Australia. The trek ended at a computer show in Sydney with the motor-home on display.

The emphasis on this second trek is on high speed applications, particularly video. His latest report is from the Sunshine Coast, north of Brisbane in Queensland. In 2007 I visited University of the Sunshine Coast, looked at their computer aided learning and the Thinlinx computer company (makers of thin client computers) at their technology park.

Wireless audio and clicker system for events

At a conference I attended today there was a device which looked a bit like a Blackberry smart phone on the desk in front of each delegate. This turned out to be a "IML Connector" from IML Ltd (Australian agent is Neil Agass). At the end of each presentation we were asked to insert the smart card provided with our registration into the top of the device. It then displayed my name and promoted me for an answer to the question the presenter was asking. This is much like the "clicker" devices used for student feedback in some course, but the device also has a small colour screen to provide feedback. There is also a microphone and loudspeaker ( and a headset socket) for two way audio and translation services. Of course the same facilities could now be provided using a smart phone, but it would be handy for events. The units looked very robust and able to stand up to being dropped on the floor. Of course as the devices are pocket size and wireless, they would be easy to steal, but presumably are not of any use to the theft without the back end system.

Broadband for the Bush

Dr Ian Oppermann, Director of the CSIRO ICT Centre talked on "Broadband for the Bush", at an Australian Computer Society meeting in Canberra on 10 August 2011.

Ian Oppermann started his presentation by making the case for CSIRO's ICT credentials, referring to CSIRO's development of CSIRAC (the fourth electronic computer in the world) and the invention of WiFi technology. He pointed out Australia is a big country with a small, literate population, but only 17th in the world for broadband take-up. Ian related how the world are looking to the NBN as a model for national broadband. Ian then pointed to the aging population and resulting increase in health costs, which broadband could help reduce.

The next point wast that Australia is increasingly a services economy. At CeBit Senator Conroy pointed out that Australia's productivity has dropped in the past decade, using statistics from "Australia's Productivity Challenge" (Grattan, 2011). Mining is very productive (in $ produced per hour of work), most services industries (including education) are not. Compared to the USA, Australian productivity is dropping and if mining is excluded Australia is the lower segment compared to OECD countries.

Ian mentioned he had been doing some work in smart grids and this was a conservative industry (as is health). Health expenditure is about 9% of GDP. eHealth records can reduce costs, assuming privacy and other issues can be addressed (I see the latest electronic Journal of Health Informatics is on Smart Healthcare Systems).

Another area is smart technologies, with CSIRO having developed a Care Assessment Platform, which interacts with the patient via a smart phone. The application provides the patient with better more personal service and reduces costs.

Another is a Virtual Critical Care Unit (ViCCU). This allows specialists at major hospitals to advise staff at regional ones, via a telecommunications link, reducing the need to transport patients. As Ian pointed out the major barrier with this is not the ICT, but fitting it to the medical need and training the medical staff to use the technology.

Ian then shifted the topic from e-health to e-Government, from with the example of staff at government agencies available on-line to help fill in forms. That may sound trivial, but a considerable amount of staff time and customer frustration can be saved by this. One point I would disagree on is the need for high resolution real time video for this application. Those who have grown up with text messaging may be more comfortable with that mode. This can also be near real time, making it more convenient for the customer and more efficient for the organization.

CSIRO, NBN Co and others have set up the Australian Centre for Broadband Innovation (ACBI) to research broadband applications, including for the NBN. The NBN fiber will cover 93% of the population, fixed wireless 4% and satellite for the remaining 3%. It should be noted that fiber covers only a tiny area of Australia. As Ian pointed out the fiber is symmetrical, whereas the satellite is not: that is more data can be transmitted from the satellite than can be transmitted to it. CSIRO is researching high speed symmetrical terrestrial wireless data ("Ngara") which can extend the coverage area and the speed. This would be very significant for regional Australia and the world. However, in my view, Ngara will take years to develop and so the current NBN plans should continue.

Dr Oppermann will also speak in Sydney 29 August 2011. Dr Darrell Williamson, Director CSIRO eResearch program, will speak on the same topic in Darwin 8 September 2011, Adelaide 28 September 2011 and Perth 16 August 2011. Dr Alex Zelinsky, CSIRO Group Executive of Information Sciences will speak in Brisbane 13 September 2011.

Australian High Speed Rail Needs the NBN

The Minister for Infrastructure and Transport, Anthony Albanese, released the report "High Speed Rail Study - Phase One" on 4 August 2011. This looks at the economic viability of routes for high speed rail on the east coast of Australia, from Brisbane to Melbourne, via Sydney and Canberra at an estimated cost of $61B to $108B. The first report looks at corridors, station locations, cost, number of passengers, social and regional benefits. The report is open for comment until the end of September.

Scope for New Optimal Cities on Rail Route

The ADC Cities Report, was launched by Minister Albanese in October 2010. This suggested 250,000 to 300,000 people being the optimal size for units of a livable city. Any new high speed rail plan for Australia should include expanding existing towns, or building new cities along the route. The enhanced access of high speed rail line (and broadband discussed below) would allow these settlements to be viable sooner, at a smaller size and at lower financial and environmental cost.

Canberra could be one such city, with one transport interchange for the high speed rail servicing the city. A light rail network would connect the railway station to Canberra's five town centres. Each of the town centers would be increased in population to 300,000, expanding Canberra's population by about five times to 1.5 million, without increasing its area.

Broadband synergy with high speed rail

One major failing of the report is that it does not take into account the effect the Internet will have on transport and settlement patterns. The Australian Government is investing in the NBN, a national fiber optic and fixed wireless network. This will allow more flexibility for the location of jobs and the provision of services. High speed rail could be planned to complement the NBN, allowing new cities to be built in inland Australia. The combination of the NBN and high speed rail would provide access to jobs and services for cities which would otherwise not be economically, or socially, feasible.

Wireless Internet can also be used to increase the allowable travel time for high speed rail. Passengers who have access to high speed broadband will be willing to have extended travel times as they will be able to be entertained, or work, on route. This can lower the cost of the system, by reducing the required speed of the trains, reducing the cost of infrastructure by tens of billions of dollars. The reduction of rail development cost would be sufficient to pay for the entire NBN.

The Internet and high speed rail could also be used to make the delivery of goods more environmentally efficient. While high speed rail is normally considered for passenger transport, it is also used for the transport of high value goods. As an example, the French national railways run a fleet of purpose build mail trains SNCF TGV La Poste. In the Australian case it is more likely that mail and packages would be carried on the rail passenger services, much as mail is transported on passenger aircraft. Palletized freight could be transferred quickly from train to cargo trams, to eliminate the need for trucks.hospitals.

A change is now taking place in the way retail purchasing occurs, with good now ordered on-line and delivered. The change from air to rail for packages would reduce the environmental impact and lower the cost, allowing Australian cites along the routes to be serviced more easily.

The combination of the Internet and high speed rail could replace much of the expensive infrastructure normally needed for building a city, with attractive new settlements built quickly along the rail corridor.

High Speed Rail Development

In the decades since the Australian Government started considering high speed rail, networks have been built in Europe and Asia. The technology has matured to the point where Australia could purchase high speed speed trains from about a dozen European and Asian suppliers.

As the new government report points out, Australia can choose from trains designed to operate on upgraded existing track at lower speeds and dedicated very high speed tracks. The UK and USA have attempted to speed up old track with new trains with poor results. Better results have been achieved by Italy and Germany. The use of magnetic levitation has also not proved cost effective.

The difficulty is the planning decisions needed to make the large investment in track viable. High speed rail makes sense only if there are going to be new cities built along the route and the resulting increase in land value can be used to pay for the railway.

In 1995 I rode a Swedish X2000 high speed Tilt Train being tested from Sydney to Canberra. While the train was very comfortable, the track did not allow high speed. In 2004 I traveled from London to Brussels, Berlin and Hamburg by the Eurostar, Thalys and ICE high speed trains. This technology is now an everyday reality in much of the developed world and is being introduced into some developing nations.

Executive summary

A strategic study on the implementation of a High Speed Rail (HSR) network on the east coast of Australia (the study) was announced by the Minister for Infrastructure and Transport, the Hon. Anthony Albanese MP, on 5
August 2010.

The study is being conducted in two phases. Phase 1, undertaken between January and June 2011, has assessed the likely range of costs, identified potential corridors and stations, estimated the potential future market demand for HSR, and considered potential social and regional development impacts of a HSR network.

Phase 1 has not examined the financial feasibility of HSR on the east coast of Australia and therefore does not include a benefit versus cost analysis. Phase 2 will examine the financial feasibility of HSR, identify an optimum route alignment, refine patronage and cost estimates and investigate potential financing options.
This report provides the outcomes of phase 1.

Cost estimates and risk

The risk-adjusted cost estimate for the implementation of an overall HSR network would fall within the range of $61 billion to $108 billion (in $2011) depending upon the combination of corridors selected, reflecting the level of confidence for this phase of the study.

The risk-adjusted cost estimates include land acquisition, stations and city access, maintenance and stabling facilities, power infrastructure, civil and rail infrastructure and IT and ticketing systems. They exclude client planning and procurement management costs, which are likely to be in the order of 10 to 15 per cent of the estimate. They also exclude operating costs (including a leasing cost for the rolling stock).

The land cost component for the HSR network is approximately $6 billion (in $2011). Acquiring, or otherwise preserving, the corridor in the short-term could reduce future costs by reducing the likelihood of additional tunnels as urban areas grow and preferred corridors become unavailable.

International experience suggests it is unrealistic to expect the capital cost of a HSR network to be recovered.

Corridors

Corridors short-listed for further analysis in phase 2 were:

• Coastal corridors between Brisbane and Newcastle, with potential variations around coastal cities and the Gold Coast.
• The Central Coast corridor between Newcastle and
• Sydney.
• The Hume Highway and Princes Highway corridors between Sydney and Canberra, via Southern Highlands.
• The Hume Highway corridor between Canberra and Melbourne, via Riverina, Murray, and with a potential route option via the Goulburn Valley.

These short-listed corridors lie within the green band shown in the following map. It is recommended that this green band define the study area for phase 2.

The short-listed corridors broadly:

• Follow the alignment of the existing long-distance rail network.
• Provide access to larger regional towns and cities along coastal New South Wales (NSW) and inland Victoria enhancing the accessibility of these areas.
• Have lower capital costs for infrastructure and land acquisition than other options.
• Have the highest net benefits of those options examined.
• Minimise potential impacts on national parks and other sensitive land uses.

Urban access in major metropolitan areas would be predominantly by tunnel. Within urban areas, the combined construction and land costs involved in tunnelling are comparable with those of surface alignments and would permit higher operating speeds and reduce environmental impact.

Regulatory frameworks exist to protect infrastructure corridors in each state and territory, although there are differences between approaches.

Stations

The following city centre station locations were short-listed for further analysis in phase 2:

• Roma Street Station and South Bank in Brisbane.
• Central Station, Eveleigh, Homebush and Parramatta in Sydney.
• Southern Cross Station and North Melbourne in Melbourne.
• Civic and Canberra Airport in Canberra.

Patronage demand analysis suggests that central business district (CBD) locations would be the major trip generator and attractor in each city. Stations closest to the CBD would generate the most demand for a HSR network.Peripheral stations were considered for Brisbane, Sydney and Melbourne, typically located towards the urban boundary where there is good access to the arterial road network. Zones in which these stations should be considered are proposed, with the final location of periphery stations subject to the optimum alignment of HSR tunnels, availability of appropriate sites and potential transport connections.

Sydney and Melbourne airports have not been short-listed because initial patronage demand forecasts indicate most HSR demand would be for travel to the CBDs, rather than to airports. Further analysis has been recommended in phase 2 to confirm assumptions made in phase 1 regarding demand for access to air services.

The following regional areas have sufficient size and demand to warrant a regional or parkway HSR station, although other regional station opportunities may exist:

• Brisbane to Newcastle: Gold Coast, Far North Coast, Northern Rivers, Mid North Coast
• Newcastle to Sydney: Central Coast
• Sydney to Canberra: Southern Highlands, Illawarra
• Canberra to Melbourne: Riverina, Murray, Goulburn Valley

HSR demand is relatively insensitive to the precise location of regional stations if appropriate access is provided between the nearest cities or towns and the HSR station.

Cost estimates and risk for short-listed corridors

The risk-adjusted cost estimates of the individual short-listed corridors are presented below. The risk-adjusted cost estimates are expressed in terms of P10 to P90, derived from probabilistic risk analysis. The P10, P50 and P90 estimates have a 10 per cent, 50 per cent and 90 per cent chance of not being exceeded respectively.

...

Forecast patronage demand

The population of the east coast states and territory of Australia is forecast to increase from 18 million people in 2011 to 28 million people by 2056. Over 100 million long distance trips are made on the east coast of Australia each year, and this is forecast to grow to 264 million long-distance trips over the next 45 years.

On the basis of demographic forecasts, assumed fares and operational characteristics, the patronage demand forecasts suggest that by 2036, 54 million people may use an HSR network each year. Regional demand represents a significant component of total patronage, with approximately 50 per cent of travel found to be related to areas outside Brisbane, Sydney and Melbourne.

It is predicted that approximately eight million passengers could travel on a HSR network between Sydney and Melbourne in 2036, and 3.5 million passengers between Brisbane and Sydney in 2036. This equates to approximately half of the projected air market for both sectors in 2036.

These forecasts assume inter-city HSR fares comparable with inter-city air fares.

Travel on HSR between Newcastle, the Central Coast and Sydney is predicted to be approximately 15 million trips in 2036, of which approximately five million would be commuting trips. These forecasts assume HSR fares between Newcastle and Sydney would be $16.50 for commuters, $30 for non-business travellers and $60 for business travellers (one-way in 2011 dollars). Between Gosford and Sydney, HSR fares are assumed to be $14.25 for commuters, $26 for non-business travellers and $53 for business travellers (one-way in 2011 dollars).

Lower fares for commuters reflect a potential subsidy for these trips.

Forecast patronage demand was found to be sensitive to changes in HSR fare levels, but less so to changes in air fares, as regional travel demand, of which air travel is a relatively small component, would be less affected.
Patronage was also found to be sensitive to HSR travel time, with mainly inter-city travel affected, due to the close competition with air.

The study confirmed that inter-city non-stop running times could be approximately:

• Three hours between Brisbane and Sydney and Sydney and Melbourne.
• Forty minutes between Newcastle and Sydney.
• One hour between Sydney and Canberra.

Key project parameters

Key project parameters for the phase 1 study included:

• Economic analysis assumed an appraisal period of 20 years from 2036, being an indicative operational year for an HSR network.
• The network infrastructure would be a double-track standard-gauge electrified line with maximum operating speed of 200 km/h within urban areas and 350 km/h elsewhere.
• Services would initially be operated by eight car sets with the potential for train size to be increased to 12 or 16 cars as required by patronage demand, and would be a mixture of inter-city express services and regional services stopping at intermediate stations.
• Non-stop travel times between the major centres would depend on the precise alignment selected but would typically be around three hours between Brisbane and Sydney and Sydney and Melbourne and 40 minutes between Newcastle and Sydney.
• The patronage forecasts allowed for accessibility of HSR stations, as well as the relative costs, travel times and service frequencies of alternative modes.
• Non urban stations would serve major regional centres, either directly or as parkway stations. These would typically be at intervals of 70 to 100 kilometres, although closer spacing is likely if sections also carry outer suburban regional services.
• Access from the urban boundary to city centre stations in major metropolitan areas would largely be through dedicated tunnel.
• HSR fares were assumed to be similar on average to current inter-city air fares, air travel times were assumed to be similar to current times, and HSR service frequencies were assumed to be hourly or better, depending on route and service type.
• Commuter demand modelling for the Newcastle to Sydney corridor was based on fares of $16.50 and $14.25 for Newcastle to Sydney and Gosford to Sydney respectively (one-way in 2011 dollars). Lower fares for commuters reflect a potential subsidy for these trips.

Overview of study methodology

Patronage demand forecasting

A base corridor was used to predict patronage of a HSR network in 2036, based on forecast travel demand and assumptions about competing modes.

An east coast model and a Newcastle to Sydney model were developed to address the following questions:

• What are the main geographical markets in the east coast corridor that a HSR network could potentially serve?
• What is the size of these markets and how are they split between alternative transport modes (car, rail, coach and air)?
• How would these markets grow in future?
• What is the potential for diversion from existing modes to a future HSR network?
• How sensitive is the level of that diversion to HSR performance and to the future scenarios?

The east coast model was designed to estimate market size and mode share from the National Visitors Survey, which includes business and non-business trips over 50 kilometres between the main cities and the towns in the corridor, but excludes commuting trips.

Travel demand growth was projected as a function of future population growth in the corridor and income growth, based on techniques used by Bureau of Infrastructure, Transport and Regional Economics (BITRE). Models of mode choice and induced travel were developed using a combination of international and local evidence to estimate diversion to HSR services and the induced travel brought about by consequent improvements in accessibility.

The Newcastle to Sydney model had a similar form to the east coast model, but focussed on commuting travel.

Estimates of the market size and mode shares were derived from the 2006 National Population Census.
Growth in commuting demand was then projected as a function of the future population growth projections in the corridor and growth in employment in Sydney and Parramatta. A model of commuter mode choice in the corridor was developed to estimate diversion to HSR services.

The presence of a HSR service to Sydney could substantially improve the accessibility of Sydney’s employment to the workforce resident in the corridor, encouraging a larger proportion of the workforce to commute to Sydney (or Parramatta). A model of the relationship between this propensity to commute and accessibility has been developed using the evidence of current commuting propensities in the corridor (derived from the Census).

Model outputs were benchmarked against international HSR systems and previous Australian HSR studies.
Corridor appraisal Long-list corridors were identified within the study area to enable a broad comparison between, for example inland corridors and coastal corridors. These were selected on the basis of:

• Long-distance travel demand characteristics, including towns and cities linked by air routes. These centres include coastal cities in northern NSW and inland cities through southern NSW and northern Victoria.
• Existing transport corridors, as they tend to link regional cities and towns. These are broadly the New England and Pacific Highways through northern NSW, and the Hume and Princes Highways through southern NSW and Victoria.
• Corridors considered in previous HSR studies to provide a comparison using current population, patronage demand, environmental and engineering information.
• Major road and rail projects to identify potential synergies for inter-operability, congestion relief or shared use of corridors.

An initial appraisal assessed long-list corridors qualitatively against a number of criteria: potential development benefits, potential connectivity with other transport systems, land use and environment impacts, potential future population catchment, and indicative capital costs.

Poorly performing corridors were excluded from further analysis, while the best performing were taken forward to a medium-list.

A largely quantitative appraisal of the medium-list corridors was undertaken to identify a short-list. This analysis was undertaken on corridors from city centre to city centre (including city access corridors). The appraisal compared corridors against a base corridor for each segment of the study area using four criteria: land use and environmental impacts; costs and benefits; social, economic and regional development; and policy and strategy fit.

Station appraisal

Four types of HSR station have been identified: ‘city centre’, ‘city-peripheral’, ‘regional’ and ‘airport’. City centre and peripheral stations serve the city and wider metropolitan areas, while regional stations connect regional communities to each other and the capital cities.
Airport stations could provide access to air services for HSR passengers.

For each capital city, a long-list of possible city centre and city-peripheral stations (and associated access corridors) was identified based on market proximity, transport capacity, surface land use and environmental impact. Potential city centre HSR stations were assessed qualitatively to identify a medium-list, with further analysis and assessment undertaken to identify a short-list of stations.

Potential regional and parkway stations were identified on the basis of likely patronage demand to regional areas.

Cost estimation

Costs have been estimated to enable the comparison of various corridor and station options (together with economic benefits and other factors). They have been based on the strategic information available at this stage of the study only and a probability assessment has been undertaken to confirm a confidence range for the estimates.

Some cost issues, such as timing or prioritisation of corridors, are common to all options and have therefore been excluded from the appraisal. Costs were also considered to be comparative against a base option, rather than absolute against a without-HSR scenario.
These issues are expected to be considered in phase 2 of the study.

Costs for the comparative assessment of medium list corridors were estimated using quantities for representative alignments and unit prices developed from actual construction project data. Station costs were estimated on the basis of predicted size, construction method and physical location. It was necessary to use a range of assumptions in preparing these cost estimates, due to the strategic level of information available for potential corridors and stations. Risk associated with these assumptions has been considered using probabilistic estimation techniques.

Further issues for consideration

While this study has recommended a study area for phase 2, it has identified five key issues that need to be resolved to refine route alignments further:

• The Newcastle to Sydney corridor (Appendix A) has significant topographical and environmental constraints. In addition, existing road and rail links are congested, particularly for rail freight. The population of this region is forecast to grow, placing additional pressures on the transport system. There are several options for integrating HSR services with the conventional inter-urban services which need to be examined in more detail.
• HSR access to Sydney’s CBD could be directly to a terminus within this vicinity, or indirectly through a terminus in either Parramatta or Homebush (combined with urban rail services). The analysis in this study indicates significant differences in the capital cost and travel demand of these two options, with a HSR station in Parramatta potentially reducing patronage demand by 10 per cent. Further analysis is required to confirm the preferred location of a HSR station in Sydney, and the potential for integrating existing and proposed urban rail services with HSR.
• Wollongong and the Illawarra Region have a significant population that may benefit from HSR services. However, the surrounding terrain makes the provision of HSR infrastructure challenging and a corridor directly serving Wollongong is likely to have more significant environmental impacts than an inland corridor via the Southern Highlands. Further engineering and environmental appraisal is required to confirm the preferred alignment in this region.
• The phase 1 study has identified an access corridor in Melbourne which passes close to Melbourne Airport. While HSR services will not provide suitable Airport Rail Link services, there are potential synergies from the joint use of an access corridor and infrastructure by HSR and the proposed Airport Rail Link services between Melbourne’s Tullamarine airport and the city’s CBD.
• This study has identified a corridor following the Federal Highway as the most suitable access corridor to Canberra, with relatively low environmental impacts, lower costs and a good strategic fit with planning frameworks. To the south and west, the corridor should follow an alignment serving the Riverina and Albury-Wodonga. These two corridors could be used to access Canberra in a ‘through’ or ‘spur’ configuration. These alternate configurations would affect the length of corridor through Canberra, the form of HSR station and may require a HSR junction to the north of Canberra.

Further operational and engineering analysis is recommended in phase 2 to examine the impacts of these configurations on HSR patronage demand and costs ...

Scope of phase 2

The second phase of the study will build on the first, but will be considerably broader and deeper in scope2. On the basis of detailed investigations and analysis, relevant international experience and the appraisal of alternatives, the second phase will be required to provide advice on:

• The medium- to long-term projected travel market.
• HSR system options that could serve the projected travel market effectively.
• The aggregate and segmented travel demand and market shares that could be expected to be attained.
• Preferred corridor, alignment, transport product(s) and system specification.
• The optimum program for staging the physical construction of the preferred HSR system.
• The specific environmental, social, urban and regional development and economic impacts of the recommended HSR program, and the overall net cost or benefit of those impacts to Australia.
• The nature and cost of complementary access projects and their contribution to achieving the assessed performance of the HSR program.
• The financing needs, financial performance and commercial viability of the HSR program.
• Any commercial financing gap and ways of funding such gap.
• The key risks to the HSR program and its successful performance, the implications of these risks and possible mitigation measures, if any.
• The most appropriate institutional framework for governance, planning, procurement, construction and operation of the HSR program and for the implementation of integrated urban and regional development policies in the HSR corridor.
• An effective implementation plan for creating the recommended institutional framework and delivering the HSR program.

Connecting a TV to the Internet Part 4: success

In "Connecting a Samsung TV to the Internet Part 3" I had decided to reconfigure a low cost wireless router, to be a repeater bridge using the open source DD-WRT software. This was so I could plug a TV into the Internet. I was able to get the TV to "ping" the gateway, but not communicate DNS service. I tried that of the router and of BigPond (the ISP being used), with no success. However, when I used the IP address of the gateway for the DNS, this worked (presumably this then is just relayed to the router).

The Samsung TV then downloaded some software updates and some default Apps. The apps included a news ticker service, which runs across the bottom of the TV screen, YouTube Videos and Twitter. The speed of download of video is reasonable, given that the signal is being relayed by WiFi. The image quality of the video is remarkably good. But after all the effort involved, it is a relief it works at all.
