T-Mobile.Key indicators show size and success of technology.

T-Mobile Group operates in excess of 160 thousand radio access nodes, and

serving more than 120}mn customers generating more than 500}bn mobile minutes.

Mobile data demand taking-off with ca. 2}TByte /month, more than

10Gbps BH throughput and a projected 60% CAGR over the next 5 years.

Across key radio access technologies such as GSM, UMTS, WiFi and WiMax

A technology organization of employees ca. 6,000 in Europe alone, covering network and IT

design & development, plan, build and operations.

Cost: Efficient Capex & Opex Ability to replace existing Networks Support Multi-Operator Operations / Sharing

Performance: Latency & Throughput Capacity (spectral efficiency) Link budget “leapfrogging”

Legacy Support & Ease of Migration Regulatory Environment:

Spectrum Competition

Terminals: Timely Availability Diversity & Volumes Low production cost - IPR Costs Features & Capabilities

Ecosystem: Support & Scale Diversity of Applications

Criteria for mobile broadband technology selection.LTE & WiMax are leading candidates for a complex decision.

Technology1

LTE unit price needs to be competitive (i.e., lower) than today's best UMTS infrastructure pricing

Opex per bit should be at least a factor 500 better than today’s UMTS cost base

Minimum 20 MHz per sector to realize leapfrog improvement in speed & customer experience.

Wide portfolio of advanced broadband devices (e.g., iPhone, G-Phone, MDA,…) present at network launch – supporting voice as well

License cost should be strongly reduced compared to UMTS

T-Mobile first to trial LTE under live conditions.

Worldwide first trial with LTE under live conditions.

Demonstration include highly demanding applications such as

Video streaming. High definition video

conferencing. High definition IPTV

On the 4 km test route the vehicle, which was driven at speeds up to 100km/h, demonstrated DL speeds in excess of 130Mbps and UL speeds up to 44 Mbps.

Thank you.
