Course Details
This course provides a comprehensive and detailed explanation of the UMTS Air Interface. In so doing, the architecture of the radio interface, 6 channel structures, the CDMA physical layer, the protocols, procedures and operation will all be discussed. For a complete picture, the course also includes focus on enhancements to the air interface through HSPA.
Philip Nugent
Mpirical Trainer
Phil heads up Mpirical’s technical development, advising on the latest technologies and assisting the Mpirical team with his wealth of both historical and current knowledge. Phil’s specialist area is the mobile radio and RAN space, originally focussing on 2G and 3G technologies but more recently, heavily embedded with 5G New Radio for both Mpirical and customer specific projects.
