What is LTE Cat 9?

LTE Cat 9 (LTE Category 9) is an LTE user equipment (UE) category that defines the performance and specifications – such as data rate, power, type of modulation, bandwidth, etc. – of LTE Cat 9 UE. LTE Cat 9 UEs are based on LTE Advanced (LTE-A) technology with support for a downlink data rate of 452.2 Mbit/s and an uplink data rate of 51.0 Mbit/s. They utilize MIMO (Multiple Input - Multiple Output) and Carrier Aggregation to deliver higher data rates and support 2 or 4 layers of spatial multiplexing in downlink (DL).
