grandioso

Cmq, tanto per dare materiale al 3ad, ho ritrovato anche questi link:

http://www.three.com.au/3andvodafone Also see how we're building a better, stronger Vodafone network. To get the latest update on the improvements already made and our future plans, check out Vodafone network update.

http://www.three.com.au/cs/ContentSe...=1236150762515 Right now we're building a new 850MHz Vodafone network designed to deliver faster speeds, stronger signals, and better coverage:
- The new network is particularly good for compatible smartphones (such as the Apple® iPhone®) and mobile broadband devices.
- We already have 550 sites live on the new network, and plan to have over 1000 sites by December.

Networks

Vodafone's GSM
Vodafone's 2G GSM service on 900 MHz and 1800 MHz covers 94.52% of the population. In major cities the 2G GSM network offers GPRS data connections, elsewhere the faster EDGE is available.Vodafone's 3G 2100 MHz
Vodafone's UMTS network is available in metro areas of major cities and some larger regional centres covering 80% of the population. In major cities, Optus and Vodafone share towers and a single set of 3G antennas and feeders, as well as equipment shelters for their respective base stations - and for some locations share a 3G base station as well.[3] Outside of major cities, Vodafone and Optus work independently. 3G users outside of major cities use either Vodafone 2100 MHz 3G towers, Vodafones new 3G 900 MHz 3G coverage, or fall back to GSM services.Vodafone's 3G 900 MHz
Expansion of Vodafone's 3G UMTS network was completed in October 2009, and uses 900 MHz for 3G services outside of capital cities, to equal or surpass their older GSM coverage.[4]Vodafone's 3G 850 MHz
Vodafone are currently rolling out new 850 MHz 3G towers and adding 850 MHz equipment to existing towers, to boost signal in-building, relieve capacity in metropolitan areas and provide a better experience for 850 MHz compatible smartphones. The 850 MHz spectrum belonged to Hutchison prior to the merger.Three's 3G 2100 MHz
Three operates a 2100 MHz 3G network in a 50/50 partnership with Telstra[5] (the radio networks are shared, the core networks are separate), covering approximately 56% of Australia's population. The 3G network covers Sydney, Melbourne, Brisbane, Adelaide, Perth, the Gold Coast, Canberra, Geelong, Frankston and Wollongong. In areas not covered by the joint 3G network, customers are able to roam on Telstra's Next G 850 MHz 3G network (if the phone supports it), and Telstra's 900 MHz and 1800 MHz 2G networks. This agreement allows Three to offer coverage to up to 96% of the population. The Vodafone 2G and 3G (2100/900 MHz) networks originally operated as a single network, separate to the Three network. During the merger, VHA had made no comment on their intention to combine the 3 and Vodafone networks, or offer roaming between them. However, as of late 2009, roaming onto the Vodafone's 2G network was enabled for Three customers in areas that had limited 3G coverage (e.g. blackspots), handsets now show '3 2G' instead of 'Roaming'. There are no additional charges in '3's 2G zone', although data speeds are limited.

In late 2010 VHA announced plans to consolidate the Three and Vodafone networks, in an attempt to better compete with Telstra's Next G network, which currently holds the most number of subscribers in Australia (9.3 million). The plan includes the expansion of UMTS 900/2100 MHz coverage in 900 metropolitan sites and 500 outer metropolitan sites across Australia, an end to the 3GIS network (3's UMTS 2100 MHz network, which it has a 50% stake with, the other 50% being held by Telstra), as well as the roll out of 1400 UMTS-850 base stations - 850 MHz being the same band in which the Next G network operates. VHA has spent $550 million on the project so far.[6]
