WCDMA HSPA Systems Engineering and Network Optimization

System engineer at telecom site

This course presents the basic principles of WCDMA / HSPA Radio & Access transport network planning and optimization. It will examine capacity and power budget issues, cell coverage planning and transport network planning for ATM and IP interfaces.

All planning consideration will be available for R99 CS and PS traffic and also for HSPA traffic. Optimization principles and solutions will also be covered, with due consideration for coverage planning or capacity planning optimization.

Finally, real case studies will be discussed and exercises will also be provided for better understanding of the course material.

  • Planning Engineers looking for a good background to start WCDMA / HSPA Planning
  • Transmission Engineers who wish to understand the overall radio to transport capacity and planning consideration
  • Optimization Engineers looking for a good presentation of initial planning in order to understand the future optimizing techniques or tips they should perform for 3G networks
