LTE Advanced Carrier Aggregation

Delivering successively higher data rates.

Carrier aggregation offers successively higher peak data rates as well as better broadband experience across the coverage area. 


The date rates scale with the amount of spectrum allowing 3GPP Rel 10 to support up to 5 carriers with up to 100 MHz of spectrum and commercial solutions to support up to 3 carriers with peak data rates up to 450 Mbps (Cat 5).

Higher capacity for bursty applications.

Increased data rates of carrier aggregation can be traded off to get higher capacity for bursty applications, such as web browsing, streaming, social media apps and others, meaning operators can choose a higher capacity for the same user experience, better user experience for the same capacity, or both.

Carrier aggregation benefits the whole ecosystem.


Users gain next-level user experience:

  • Higher data rates with lower latency across the network
  • Faster downloads of pictures, files, webpages, higher quality videos, etc.


Operators can make the most of all spectrum assets:

  • Higher network capacity
  • Opportunity to offer new apps/services which use higher data rates and capacity

App Developers

Developers can transform mobile experiences:

  • Substantially richer user experience
  • New immersive multimedia, such as 4K
  • Fully utilize multimedia and connectivity of modern smartphones


Manufacturers show technology leadership and differentiation:

  • Lead with early adoption
  • Offer tiered devices based on speed and device capability
  • Expand carrier aggregation proliferation to address global markets

First to announce commercial Cat 10 modem

We were the first in the mobile industry to announce a Cat 10 solution, the Qualcomm® Snapdragon™ X12 LTE Modem, which supports carrier agregation with peak data rates of up to 450 Mbps downlink and up to 150 Mbps uplink.
