iPerf is an open source software utility available for many operating systems. iPerf3 is used to measures the available TCP and UDP bandwidth along a path between two hosts and can be used for wired and wireless testing.
When using iPerf there is usually a sender/client (iPerf -c ) and a receiver/server (iPerf -s).
As part of our WiFi/wireless design process we typically conduct an onsite RF survey to understand the RF characteristics of the location and to validate our design for access point locations.
This setup involves measurement/survey software running on a laptop or tablet that can collect information about WiFi and non WiFi devices in the environment. This data is compared with WiFi signals from a temporary access point deployed for this survey process positioned at locations we believe would meet the requirements of the deployment.
iPhone and iPad users with iOS 7 and up, now have a way to view WiFi scan info (SSID, BSSID, RSSI, Channel) on devices with Apple's AirPort Utility app. Prior to this AirPort Utility update, only SSID and BSSID information was available on app store apps (non jailbreak apps).
