Updated 5G Device Test Solution Advances Comm Capabilities
The technologies specified in 3GPP Release 17 are undergoing technical trials in various countries. These new technologies need a test solution to accurately evaluate the transmission and reception performance of 5G devices.
Intended to accelerate the development of systems with high speed and capacity, Anritsu created updated software options for its MT8000A Radio Communication Test Station. The optional software, which is designed to evaluate the RF performance of 5G devices, supports technologies in 3GPP Release 17, such as 1024QAM modulation for downlink and Tx Switching 2Tx to 2Tx for uplink. This enables accurate and flexible evaluation of 5G devices with enhanced transmit/receive (TRx) performance.
The 1024QAM modulation for downlink improves data throughput compared to the current 256QAM standard for the same frequency bandwidth. And Tx Switching 2Tx to 2Tx for uplink technology improves uplink stability and speed by dynamically switching between multiple antennas based on communication conditions.
These technologies are expected to be adopted in the FR1 frequency bands used by 5G devices such as smartphones, and entertainment applications like ultra-high-definition video streaming and cloud gaming, in addition to business use cases such as teleworking and cloud services.
