LTE Cat 8 (LTE Category 8) 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 8 UE. LTE Cat 8 UEs are based on LTE Advanced (LTE-A) technology with support for a downlink data rate of 2998.6 Mbit/s and an uplink data rate of 1497.8 Mbit/s. They utilize MIMO (Multiple Input - Multiple Output) and Carrier Aggregation to deliver higher data rates and support 8 layers of spatial multiplexing in downlink (DL) and 64-QAM in uplink (UL).
