This excerpt taken from the DT 6-K filed Mar 3, 2006. Mobile broadband opens up new
dimensions in data transmission. In the 2005 financial year, T-Mobile continued to roll out and improve the
UMTS network at a fast pace, laying the focus in Germany and Austria on upgrading the UMTS sites with
HSDPA technology. During the
first roll-out phase, T-Mobile will use this technology to increase the bandwidth for data transmission in the
UMTS network from its current
maximum 384 kilobits to 1.8 megabits per second. This will bring mobile data transmission up to speeds
comparable to those achieved
with DSL in the fixed network. In the future, T-Mobile plans to increase this figure to a rate of up to
7.2 megabits per second, thereby also providing top-quality broadband
communication for mobile Internet
access. The first pilot projects that T-Mobile launched with key accounts in 2005 confirm the high
performance and reliability of the
HSDPA technology. The official launch of the HSDPA network is scheduled for spring 2006.
With the TDD (Time Division Duplex) modulation procedure and FLASH-OFDM (Orthogonal Frequency Division Multiplex) network technology, T-Mobile opted for two other innovative broadband technologies that allow transmission rates comparable with DSL in the fixed network. T-Mobile has already introduced these technologies in the Czech Republic and Slovakia, where the fixed-network broadband offering is extremely limited.
