"Today Nokia announced the Nokia 3555 for T-Mobile USA. This is one of the first 3G phones for T-Mobile USA which will use the AWS bands for 3G. As you might recall T-Mobile USA's parent corporation, DT, invested heavily in the AWS auction, spending more than $4 billion on licenses. The AWS bands more resemble 3G bands of Europe and Asia where the voice and 3G services are on separate frequencies. AWS (WCDMA IV) uses 1700MHz and 2100MHz while many North American carriers are "piggy backing" their 3G services on their existing 850MHz and 1900MHz bands. By doing so these carriers have been able to launch 3G services sooner in many larger markets however doing so means 3G services are frequently not available in smaller markets and often suffers during peak voice times. T-Mobile USA should have a distinct advantage with separate frequencies for 3G services and in some cases giving them licenses in markets or areas where the 1900MHz frequencies licenses have long been unavailable."

3G Americas Congratulates T-Mobile USA on First Major Urban UMTS/HSDPA Network Launch in 1700/2100 MHz Bands

Bellevue, WA, May 05, 2008 -

3G Americas, a wireless industry group advocating for the GSM family of technologies in the Americas, today applauds T-Mobile USA on the launch of their UMTS/HSDPA network in the 1700/2100 MHz bands. Commercially launched today in New York City, this is the first major urban deployment of 3G UMTS in the 1700/2100 MHz bands, and T-Mobile USA plans to continue its 3G network rollout across major U.S. metropolitan markets throughout 2008. Stelera Wireless also launched UMTS/HSDPA in a regional US market in the 1700/2100 MHz spectrum bands in February 2008.

T-Mobile USA is the U.S. operation of Deutsche Telekom AG’s Mobile Communications Business, and a wholly owned subsidiary of T-Mobile International, one of the world’s leading mobile communications companies.

T-Mobile's announcement brings the number of UMTS operators worldwide to 216 across 91 countries, with 61 additional networks in various stages of planning, trial, or deployment. Of these 216 commercial networks, 190 are HSDPA.

Subscriptions to UMTS/HSDPA are growing at a rapid rate. According to Informa Telecoms and Media’s World Cellular Information Service, there are an estimated 214 million subscriptions to date, and half a billion UMTS/HSDPA subscriptions are forecast by year end 2009. This figure is expected to grow to 1.8 billion by year end 2013, according to Informa.

Chris Pearson, President of 3G Americas noted, "The commercial launch of UMTS by T-Mobile USA in New York City is great news for the wireless industry, wireless customers, and a significant accomplishment for the Americas region. 3G Americas congratulates T-Mobile USA on launching their UMTS/HSDPA network and on their plans to expand their 3G footprint.”

There are nearly 500 devices supporting UMTS/HSDPA technology including handsets, PC cards, external modems, routers, femtocells and notebook PCs with embedded HSDPA chipsets to support a wide variety of frequency bands.

Pearson continued, “The 1700/2100 spectrum band is a common spectrum allocation for North, Central and South America. T-Mobile USA’s 3G launch today will help grow the entire UMTS/HSDPA wireless ecosystem for this spectrum band at an important time, as other 1700/2100 spectrum auctions are scheduled to take place this year across the Americas.”

The International Telecommunication Union (ITU) endorsed the 1700/2100 MHz Advanced Wireless Service (AWS-1) spectrum band, also known at 3GPP as UMTS Band IV, and this band is marked for auction or reserved in many countries in the Western Hemisphere. In 2006, the U.S. government auctioned the 1700/2100 Advanced Wireless Service (AWS-1) spectrum band, raising a total of $13.9 billion for the U.S. Treasury with T-Mobile USA as one of the principal auction winners.

Later this year, Canada, Chile and Mexico are expected to auction the 1700/2100 spectrum bands. Additional countries in the Americas that have reserved this band for wireless services include Argentina, Colombia and Ecuador.
