Purpose

This test is intended to characterize peak download and upload performance with balanced TDD configuration for 5G access points in ideal RF condition.

Test infrastructure

• Celona network w/ (1) AP

• iperf3 server

• UE under test

Test characteristics

This test involves the following parameters and/ or variables (inaddition to those described in the General Test Details andCharacteristics and TDD Config setup details)

Parameters

Parameter selection is based on frequency band of access point and configured bandwidth for the access point used to perform the test.

Variables

-l (length of buffer to read or write)

1300 bytes

Recorded Data

TCP

  • Download throughput

  • Upload throughput

UDP

  • Download throughput

  • Download loss

  • Download jitter

  • Upload throughput

  • Upload loss

  • Upload jitter

Procedure

TCP

iperf3 -c <iperf_server> -p <iperf_control_port>  -t 600 --logfile date_<device_under_test>_tcp_tput.txt

where

• <iperf_server> is the IP address of an iperf3 server

• <iperf_control_port> is a port on the iperf server where an iperf3 process is listening

• <device_under_test> is the make and model of the device

UDP

iperf3 -c <iperf_server> -p <iperf_control_port> -u -R --bitrate <Dl_Bitrate>M -l 1300 -t 300
--logfile <device_under_test><Testcase_id>_<Edgeip>_<Traffic_type>.txt

iperf3 -c <iperf_server> -p <iperf_control_port> -u --bitrate <Ul_Bitrate>M
-l 1300 -t 300 --logfile <device_under_test><Testcase_id>_<Edgeip>_<Traffic_type>.txt

where

• <iperf_server> is the IP address of an iperf3 server

• <iperf_control_port> is a port on the iperf server where an iperf3 process is listening

• <device_under_test> is the make and model of the device
