What is TD-SCDMA?The Solution for TDD Bands

• A highly efficient air interface ... the newest
  air interface of 3G
• ... ideal for asymmetrical data

TD-SCDMA Full integration in IMT-2000 and 3GPP
Release 4
A complete 3G solution ideal for large cells
... as well as dense urban
An ideal solution for China ideal for dense
urban capacity ... and data centric applications
An optimal complement to W-CDMA ideal for
capacity bottlenecks ... Ideal for upcoming data
traffic

Key Technologies of TD-SCDMA

• Time Division Duplex
• ... allows adaptive allocation of radio resources
• Code Division Multiple Access
• ... allows simultaneous multiple user access
• Joint Detection
• ... minimizes the interference within a cell
• Dynamic Channel Allocation
• ... leads to a reduction of interference by other
  cells
• Smart Antennas
• ... further minimizes interference

TD-SCDMA Optimizes the Efficient Use of the
Available Spectrum

Smart AntennaSmart Antenna brings Energy only
where it is needed

• With Smart Antennas ...
• Power is directed to cell areas of mobile
  subscriber activity only no power spread over
  the whole cell!
• Terminals are tracked throughout the cell

• Without Smart Antennas ...
• Power is distributed over the whole cell
• For areas without mobile activity no
  interference attenuation is foreseen

9
In China everything is bigger. even the hot
spots!

• Chinas most important provinceshave a
  significant higher population than European
  Countries
• High population areas are capacity driven and
  require special solutions for capacity
  enhancements
• There are higher Peak Population Density Areas in
  China than for example in Germany

• High population areas are capacity-driven and
  require an efficient use of the available, scarce
  spectrum.
• Therefore mobile technologies with highest
  spectral efficiency are a must
• TD-SCDMA perfectly fulfills these requirements
