Carrier Aggregation & Dual-Connectivity in 5G NR

Why Take This Course?

• Enhance your industry knowledge and skills by gaining a greater understanding of Carrier Aggregation & Dual-Connectivity.
• Train with engineers at Qualcomm Technologies – a world leader in 5G technology and wireless engineering.
• Learn online and at your own pace with our flexible eLearning format. Or, set up a live training session for groups of at least 15 people.

Course Outline:

• Learn why Carrier Aggregation (CA) is a key capability for wireless network operators and how it allows them to combine spectrum to provide the following:
  • More resources to end users
  • Improved data rates
  • An increase overall network capacity.
• Learn about some of the challenges operators face with 5G devices, including supporting all key frequency combinations across 10,000+ networks.
• Discuss how to best deploy the Dual Connectivity (DC) feature that allows user equipment (UE) to transmit and receive data simultaneously across carriers using two serving nodes for more seamless connectivity.
• Introduce Release 15 new radio carrier aggregation and dual-connectivity, deployment considerations for both technologies, and enhancements defined in Release 16.
• Learn how the technology features of CA and DC will allow operators to unleash the full power of 5G.
