Comparison between Three Schemes for the Standard Access Mode and Selection of the Architecture that is Best Suited for Australia

Comparison between Three Schemes for the Standard Access Mode and Selection of the Architecture that is Best Suited for Australia


The upgrade of the existing telecommunications network in Australia was meant to provide access to affordable, reliable and fast landline services as well as internet services. To better improve this service provision, there is need to use a cost efficient and best fit technology that will ensure the realization of these demands (McKinsey, 2010). Furthermore, the technology needs to reach to a high number of individuals in Australia (NBN Co., 2014). This paper shall present a comparison of three alternative schemes that can be used to reach 93% of users in Australia. The three schemes include a wireless-only system that is based on 4G cellular network technology with a fiber backbone connecting the base stations, A Fiber To The Node (FTTN) plus VDSL2 over copper architecture, using existing twisted-pair copper for the last part of the link between the network and the customer; and A Fiber To The Premises (FTTP) model, in which all users will be connected to the network via a Gigabit Passive Optical Network system. The comparisons shall be based on cost, ease and speed of deployment, energy consumption, expected long-term capacity for growth in the number of users and bandwidth demands of each user and competition between service providers.

Wireless-only system (4G technology)

The wireless-only system based on 4G technology was designed to offer high data speeds to users with mobile devices like smart phones or tablets. The speeds stated for this technology reach up to 150MBPs. The speeds will be fast enough to stream HD videos (Thomas, 2013). In addition, the architecture offers minimal costs in infrastructure and protocol of signaling. In fact, some of its operational parameters like radio feedback to some nodes can be achieved without any additional overheads (Akyildiz et al, 2010). The architecture requires less investment in infrastructure and this also implies less energy consumption. The scheme can also be set in a way that can further reduce the energy consumption (Akyildiz et al, 2010, pp. 237). With the developing numbers in use of mobile devices, this architecture is expected to grow further so as to continuously upgrade its speed. This scheme also allows for spectrum sharing and this reduces the competition between service providers. The disadvantage of this architecture is that not all devices support the technology. There is also the need to upgrade current devices so as to support the technology.

FTTN plus VDSL2 over copper architecture

While this technology has been deemed to improve speeds to up to 300MBPs, the reality is it won’t (Chirgwin, 2012). The scheme provides relatively high speeds. However, the cost of infrastructure is high due to the need for connecting wires. In addition, it will only cover areas that are close to the exchange centers. This implies that a lesser region will be covered. Further, the likelihood of growth requires a total growth in the infrastructure, increasing the costs. The energy consumption is not pleasant either (B&C Consulting Services, 2007). The competition for service providers is high because it’s only the providers who are closest to the users that will be in business.

A Fiber to the Premises (FTTP) model

The FTTP provides great speeds and reliability in transition of signals. Users can download and upload faster. In addition, the model can be used for a very long time. Once the fiber optic cable has been set with a cable that transmits the spectrum of light, no bandwidth will fail to be accommodated by the model. The fiber cable is also more durable than its copper counterpart in addition to the ability to be monitored by others (NBN Co., 2010). The fiber connections are ready to use for a variety of products. On the contrary, the model is difficult and expensive to install because of the need to install the fiber optic cable. It is more costly for consumers. It also requires installation of new equipment, the NID, and a power source for the NID. This implies more power consumption (Wisegeek, 2014).


Comparison of the three models reveals various advantages and disadvantages. However, the option for selection inclines towards the FTTP and the wireless-only system. This is because of their speeds and their future prospects. Each of the models provides the capacity for growth in the future. In fact, the FTTP provides a better capacity for growth because it can accommodate a very wide bandwidth. The wireless-only system is more suitable in terms of cost of installation and power consumption. For the NBN, the wireless-only system will be suitable in meeting their demand for better access model to the users.
