Iperf Throughput Test
A more thorough test is to perform a throughput test which will check the amount of data that can be reliably achieved via
the Wireless link. There are a number of software tools that we can use to check the data throughput, i.e. FTP - file
transfer protocol, Iperf, Qcheck, etc.
bandwidth measurement application that is run on a
Laptop or PC at each end of the radio link. The Iperf/Jperf application can be downloaded from
http://sourceforge.net/projects/iperf/
a over the link, calculate the results and then display the throughput
accordingly.

throughput.
All of the above procedures measure the raw data throughput and from these throughput measurements we can
determine if interference is a contributing factor in the overall performance of the modems.
Statistics 4.3
The Statistics webpage is used for advanced debugging of 450U-E. This webpage details the state of the 450U-E and
performance information. This page is typically useful to ELPRO technical support personnel in diagnosing problems with
the module.
Note: When updating the Statistics webpage, it is necessary to hold down the <Ctrl> key while
pressing the refresh button to ensure the most up to date information is displayed.
The Statistics Page is used for gathering information about how the module is connected and communicating. It is
comprised of a number of dynamic list boxes with each showing particular statistics about its function.
Interface Statistics: will show the number of bytes transmitted and received as well as the number of CRC errors,
dropped packets, fifo alarms and the different types of frames (fragmented, compressed or multicast).
tion as this will indicate how the Radios are
communicating.
Time: shows the amount of time the module has been running since its last reset.
System Log: shows a running log of information about how the modules operating system is running. This log will also
log any errors and resets.
