Here is an interesting piece taken from another site where not only NBN issues are discussed.... [Reddit] The author takes statements from the Ministers web site and discusses the point one by one... TURNBULL : Where does fibre to the premises fit? Fibre generally should be deployed in new (‘greenfield’) housing estates and wherever copper has to be replaced (unless there are particular commercial reasons not to do so). There will also be established areas where high maintenance costs or the condition of the copper renders FTTN unattractive and the best alternative is FTTP. While there is no clear economic case or mainstream consumer demand for FTTP in most areas today, this will not necessarily remain the case. Today’s applications will change and evolve, particularly with the rise of cloud services. The Coalition’s policy anticipates this possibility and ensures it is planned for. Commentary_____Basically they are admitting that FTTP is for the future of broadband, and therefore their own FTTN will become obsolete in the foreseeable future. Also theyre saying if the copper has to be replaced then theyll replace it with fibre. TURNBULL: We will issue a revised statement of expectations directing NBN Co to provide broadband services with a minimum download data rate of 25 megabits per second by the end of 2016 in all areas of Australia, and 50 megabits per second by the end of 2019 in 90 per cent of the fixed line footprint. The goal assumes the current NBN Co satellite and fixed wireless networks are deployed on schedule. Commentary______So they want a minimum speed of 50 Mbs by the end of 2019, which wont be possible with FTTN unless everyone is 500M or less from the nearest node, which means they will need a bucket more nodes or they will just use FTTP where they cant get those speeds, which sounds pretty good until you get to this bit. TURNBULL: The new statement of expectations will grant NBN Co’s board and management flexibility and discretion in technology and network design decisions. The statement of expectations will specify a limit on the public capital available to NBN Co. This limit will be $29.5 billion. Commentary______So NBN Co has to deliver a certain level of connection speed, but wont have anywhere near enough money to do it (dont forget, the Coalition claims FTTP will cost $90b+) So what we have here is an NBN that will be a mix of FTTN, FTTP, wireless and satellite (the ALP version is the same except no FTTN) that will supposedly deliver minimum speeds of 50Mbps by 2019 and will cost around $30b. This mix also means that either you will get different speeds depending on where you live ad the technology used, or some technologies will be under utilised to even the playing field. Unless someone comes up with a great new technology for FTTN thats incredibly cheap or extends viable 50Mbps speeds well beyond 500M of copper cable then were going to see either sub par connection speeds or a cost blowout.
