Purpose

This test is intended to characterize peak download and upload performance with downlink heavy TDD configuration for LTE access points in ideal RF condition.

Test infrastructure

• Celona network w/ (1) AP

• iperf3 server

Test characteristics

This test involves the following parameters and/ or variables (in addition to those described in the General Test Details and Characteristics article, and TDD Config setup details.)

Parameters

Requested DL bitrate

150 Mbps

Requested UL bitrate

40 Mbps

Duration

5 mins

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 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

UDP

iperf3 -c <iperf_server> -p <iperf_control_port> -u -R --bitrate 200M -l 1300 -t 300
--logfile <device_under_test><Testcase_id>_<Edgeip>_<Traffic_type>.txt

iperf3 -c <iperf_server> -p <iperf_control_port> -u --bitrate 25M
-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
