WISM+ Host PC
7 Using the Performance Tool in Ad-Hoc Mode
The performance of the WISM+ to a Wi-Fi enabled PC in a UDP socket configuration (in 802.11b mode) can be
measured (over the USB interface) using WIF.exe’s Tx Performance tool feature. From WIF.exe’s top menu, select…
Packets are handed to the WISM+ over the wired active host PC interface, and then transmitted by WISM+ to be
received by a remote PCs Wi-Fi (set up with an Ad-Hoc connection) using “dboard.exe” (a separate stand alone
program running). Below is a diagram of the setup…
To begin, set up the Ad-Hoc connection between the WISM+ and the remote PC by following the procedure outlined in
section: “
Now that the WISM+\Remote PC connection is in place, launch “dboard.exe” on the remote PC by clicking…
dboard.exe will capture packets & measure throughput performance. Since this the TX Performance tool uses a UDP
socket, there is no guaranteed delivery of packets (as with TCP). There may be more total packets transmitted from
the WISM+ Host PC Tx Performance test than packets received on the remote PC by dboard.exe.
About dboard.exe…
“dboard.exe” is the program which runs on the remote
PC and is use to capture the packets sent from the
host PC/WISM+ over the air.
It displays instantaneous data rate (“Current Rate”)
and a latched Peak Rate.
It displays the total number of 1500 byte packets
received.
You can scale the units of the meters in kb/s or Mb/s.
You can also reset the peak rate meter and the
packet count by pressing the “Reset” button
