5.3 Connecting wired device to AP and STA 1
The typical throughput test configuration is to have one wired device connected to the AP and 2
one to the STA, and measure throughput between the two wired devices. These devices can be 3
PCs, STBs, etc. 4
Figure 5-1 shows how to connect wired device to AP and STA. 5

Qualcomm WCN1320-based AP and STA reference designs are equipped with 1000Base-T LAN 8
(4) ports on AP router or single port on dongle AP/STA. Using these ports on the AP and STA 9
and a PC equipped with a 1000Base-T will yield the best throughput results. 10
5.4 Throughput performance test tools 11
There are a multitude of throughput performance test tools available that can be used to 12
characterize throughput performance over a Qualcomm WCN1320-based wireless link. 13
Qualcomm tests extensively with two of these tools: Chariot (available for purchase from Ixia) 14
and IPerf (free). Configuration considerations for each are provided below. 15
5.4.1 Ixia Chariot 16
When using Chariot, a Chariot endpoint must be installed on any PC that will source or sink 17
traffic (PC1 and PC2 in this case). A Chariot console is required on any PC that has IP 18
connectivity to PC1 and PC2 (it can be on PC1, PC2, or a third PC with IP connectivity). 19
To obtain maximum throughput results, the following configuration options Chariot are 20
recommended: 21
Select the High Performance Throughput script. 22
Run bidirectional traffic with at least 10 endpoint pairs in each direction of traffic (i.e., 10 end 23
point pairs from PC1 to PC2 and 10 endpoint pairs from PC2 to PC1). 24
Tests can be run in batch mode (as opposed to real-time) to prevent Chariot control traffic 25
from loading the wireless link; however, the impact of running in real-time mode is 26
negligible. 27
