5G Traffic Generator vs 5G Diagnostic Monitor

This page compares 5G Traffic Generator vs 5G Diagnostic Monitor and mentions functional difference between 5G Traffic Generator and 5G Diagnostic Monitor. It explains applications of 5G Traffic Generator and 5G Diagnostic Monitor.

Introduction:
Both are the tools used in 5G lab test set up. As shown 5G compliant UE and NB are connected over the air using array antennas. As shown traffic generators are used to provide traffics for both UE and NB as required to establish data connectivity between them. Test application server software is needed along with 5G traffic generator. Diagnostic monitor is used to monitor logging of messages exchanged between UE and NB.

5G Traffic Generator and 5G Diagnostic Monitor

5G Traffic Generator

Following are the functions applications of 5G traffic generator.
• It is used to measure 5G throughput. It can be used to verify operability of other 5G test cases.
• Traffic can be generated using internal MAC padding or using iPerf.
• The iPerf is a tool which requires configurations on both server as well as client. It uses UDP protocol.
• It measures PASS/FAIL criteria based on average data rate (in units of Mbps).
• Following table-1 lists out iPerf configurations at client/server.


Configurations Description with value
Transport protocol UDP
Packet Size 1418 bytes (IPv4) and 1300 bytes (IPv6)
Transmit time 65 seconds

5G Diagnostic Monitor

Following are the functions applications of 5G diagnostic monitor.
• Diagnostic monitor is used to capture every test session between UE and NB.
• It logs various parameters at 5G NB side and 5G UE side. Following table-2 summarizes the same.


Item NB side UE side
Signaling message All All
Received signal strength Strength of Signal from UE DL RSRP/RSRQ
Serving cell information Cell ID/CP/5GARFCN Cell ID/CP/5GARFCN
xPDSCH or xPUSCH configuration # of antenna, transmission mode, spatial rank, RB allocation, PMI Index, TB size, modulation scheme -As mentioned in "5G NB Side" column-
Physical Data Throughput Peak, Average throughput BLER Peak, Average throughput BLER
CSI report CQI/PMI/RI repored from 5G UE Measured CQI/PMI/RI
Beam Information Scheduled Beam Info. Beam ID, BSI, BRI
