Thanks to Neil Mac for constantly kicking the tyres on wiperf and making me think twice about stuff -).Your efforts, ideas and patience are very much appreciated my friend, thank you. A special mention to Tris Kipling who has been valuable source of feedback and ideas through his field experience of using wiperf.Thanks again to Mario Gingras for the SMB testing idea and code - another valuable addition to the feature set of the tool.The MOS score code in the UDP iperf test results was kindly donated by Mario Gingras - his time and effort in developing this are very much appreciated.I could not have put them together without your ideas and JSON code - thank you so much! Thank you to Eric Garnel & James Whitehead for their invaluable contributions to the Grafana dashboards included in this distribution.He kicked this whole thing off and it definitely wouldn't have happened without him. Thanks to Kristian Roberts for his invaluable input, testing and guidance on Splunk.The data server must be an instance of either:įor more information about wiperf, please visit the wiperf documentation site Further Documentation References The app can operate as a client and/or server. Introduced in 802.11k, a power measurement calculated as INT ( (dBm + 110) 2). Tests are run on the wiperf probe at a configured interval (usually 5 minutes) and collected data is sent back to a data server over a network connection between the probe and data server (no connection = no data collection). WiFiPerf 99.99 WiFiPerf is a bandwidth performance measurement app for iOS. WiFi Glossary Received Channel Power Indicator (RCPI) A power measurement introduced in802.11k calculated as an average of all received chains during the reception of the data portion of the transmission. It is not designed to replace large-scale commercial offerings that provide wireless and end-user experience monitoring in a far more comprehensive and user-friendly fashion. Wiperf has been primarily designed to be a tactical tool for engineers to deploy on to a wireless network where perhaps issues are being experienced and some longer term monitoring may be required. ( NOTE: There is no graphing/reporting capability on the wiperf probe itself) The results must then be sent back to a Splunk or InfluxDB server (which we'll call the "data server") to provide a reporting capability. Tests may be performed over the wireless or ethernet interface of the probe unit. Wireless connection health check (if wireless connected).The probe can run the following tests to give an indication of the performance of the network environment into which it has been deployed: It is primarily intended to provide an indication of the end-user experience on a wireless network, but may also be used as a standalone ethernet-connected probe to allow a wired experience to also be tested. Wiperf is a utility that can be installed on to a WLAN Pi or a Raspberry Pi to act as a network probe running a series of network performance tests. (Version 2.1 is hot off the presses, check out the new features & fixes here) The larger the window, the fewer the acknowledgements and the faster the data transfer.(Looking for the old pre-v2 docs? Try this: link) If the acknowledgment isn’t received, the sending device will then resend the data. TCP (transport control protocol) requires the receiving device to periodically acknowledge the receipt of data, and TCP window size determines how much data can be sent before the sending device must stop and wait for that acknowledgment. Lal Shimpi theorizes that OS X is properly dynamically resizing the TCP window size when IPERF is running, but not when actual files are crossing the network. In my own testing, I clocked the file-transfer throughput at a meager 140 mbps at close range (eight feet separating the router and client) while copying a 10GB collection of small files from a new MacBook Air to an older MacBook Pro on the same network (both machines were equipped with SSDs). MacBook Air, which is outfitted with an 802.11ac Wi-Fi adapter, is radically slower when it comes to transferring real-world files over a wireless connection.
