3-day instructor-led training, 0900-1700

WCDMA/UMTS Air Interface course gives the detailed description of the WCDMA FDD technology and its use in the UMTS network. The training focuses on physical layer operation and procedures and other functions closely related with the physical layer. The training presents functionality related with the use of R99 dedicated channels. The upper layers of the UMTS air interfaces and HSPA is covered in other trainings.

The participants should have attended the UMTS Basics or have the equivalent knowledge on WCDMA/UMTS.

Radio network planning and design engineers, radio network tuning engineers and access transport network design engineers. It is recommended for personnel who need an understanding of the WCDMA /UMTS air interface.
