T-Mobile 3G rollout.

After spending $4.2 billion on the AWS auction, T-Mobile says to spend nearly $2.7 billion on a network upgrade. The upgrade will start this quarter and end in 2009 with most network completed by 2008.

New devices will have to be developed to work in the new 1,700-MHz and 2,100-MHz bands. While many European countries have a 2,100-MHz band as well, their band is configured differently, so European 2,100-MHz devices will not be able to work well on the American version.

T-Mobile's 3G rollout will include HSDPA, which will start during the fourth quarter of this year and will extend through 2007 and 2008, costing around $2.1 billion for the buildout through 2009. Consumers will be able to buy 3G handsets and services beginning in mid-2007
