LTE-Advanced, standardized in 3GPP Release 10, will enhance LTE into a true 4G mobile communications technology while meeting the IMT-Advanced requirements in terms of peak data rate and spectral efficiency. Carrier aggregation is the most demanded feature of the LTE-Advanced feature set because it will allow network operators worldwide to aggregate their different spectrum holdings. In the third part of the Rohde & Schwarz webinar series on LTE UE RF measurements, we will discuss the details of carrier aggregation, its different types and its impact on how to test a device that supports carrier aggregation. Emphasis will be on receiver testing using the R&S®CMW500 wideband radio communication tester.

Attendees will learn:

  • Fundamentals of carrier aggregation as part of the LTE-Advanced (3GPP Release 10) feature set
  • How to test carrier aggregation (CA) capable LTE handsets


  • Basic understanding of mobile communications standards
  • Basic knowledge of LTE 3GPP Release 8 principles

Who should attend:

  • Engineering and lab managers
  • Research and principal engineers
  • RF and transceiver design engineers
  • Software and protocol development engineers
  • Network and systems & test engineers
  • Application and support engineers
