Technology Primer: Carrier Aggregation
- Course Length:
- 0.5 day Instructor Led
LTE network operators are trying to reduce and consolidate the different mobile networks they have to maintain, resulting in a fragmented set of carriers possibly spread across different bands. With the introduction of LTE-Advanced, operators have an opportunity to use features such as Carrier Aggregation (CA) to maximize their RF capacity and efficiency. We start with a short introduction to various features of LTE-Advanced, where CA is introduced along with its key drivers and benefits, followed by a closer look at the various changes made to the LTE air interface to support CA, including important LTE operations such as bearer setup, traffic management and handover. The primer finishes with a quick look at some of the other features introduced as part of LTE-Advanced, including Coordinated Multipoint (CoMP) and new MIMO options.
A high-level technical overview to personnel involved in product management, marketing, planning, design, engineering, and operations.
After completing this course, the student will be able to:
• Identify the targets and key features of LTE-Advanced
