LTE Cat 17 (LTE Category 17) 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 17 UE. LTE Cat 17 UEs are based on LTE-Advanced Pro technology with support for a data rate of 25,065 Mbit/s on the downlink. They provide higher data rates by utilizing MIMO (Multiple Input - Multiple Output) and 32 Carrier Aggregation. These UEs support 8 layers of spatial multiplexing and 256-QAM in downlink (DL) and 64-QAM in uplink (UL).
