It would cost well over $40 billion.
To create a "nationwide" network like that in Australia would cost around $50 bn, almost the entire country lives along the east cost. Also, the population is far smaller, so you're talking about a $50 bn network that mostly stretches down one coast, and is only required to serve around 23 million people right now. That's just for home internet, not 4G tech that's far beyond what we have now in terms of speed, and not JUST for customers of a single company.
no it would not cost $50 billion ROFL where are you getting your numbers?
Project type: 3G mobile network WCDMA
Estimated investment: US$500 million on equipment, plus another US$306 million
Vodafone Australia has started the first phase of a two-stage rollout of 3G across Australia. The network will be based upon the popular European standard for 3G networks, WCDMA (wideband code division multiple access). Australia already has its first 3G network courtesy of Hutchinson Telecom trading under its 3G brand name "3".
Vodafone Australia has 2.59 million subscribers across the country, making it the third largest mobile telecommunications company in Australia. The company is working in conjunction with Optus Mobile (a subsidiary of Singapore Telecom) to develop a second 3G network - with the first phase covering the major cities and then a second stage rollout to cover rural areas of the country - following an agreement between the two companies signed in October 2004.
Vodafone Australia and Optus Mobile both won 15yr 2GHz spectrum 3G licences in the March 2001 auction for the 1,885MHz to 2,025MHz and 2,110MHz to 2,200MHz bands for US$253.55 million and AU$248.87million, respectively, and are being allowed to develop a jointly-run network.
The equipment investment for the network is US$500 million, while the other construction costs are US$306 million (these costs will now be shared between Vodafone and Optus [Optus hopes to save over AU$130 million]). The network is being started in late 2004 and is scheduled to be complete and operational by early 2006. Vodafone and Optus will share the network but will still compete for subscribers and operate totally separate customer service operations.
