"WCDMA 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, as well as, HSPA.
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 air interface.
