This page delves into the parameters of LTE Advanced User Equipment (UE) categories, specifically focusing on downlink (DL) and uplink (UL) characteristics such as DL-SCH, UL-SCH, and data rates.

We’ll cover LTE Advanced UE categories including:

  • Category 6 (Cat6)
  • Category 7 (Cat7)
  • Category 8 (Cat8)
  • Category 9 (Cat9)
  • Category 10 (Cat10)
  • Category 11 (Cat11)
  • Category 12 (Cat12)

Here’s a quick look at the earlier LTE UE categories:
