What is WiFiMon?

WiFiMon is a WiFi network monitoring and performance verification system. It is capable of detecting performance issues, visualising the achievable throughput of a wireless network for each user, and providing technical information about a WiFi network (e.g., signal strength, link quality, bit rate, etc.). WiFiMon leverages well-known performance verification tools (e.g., Akamai Boomerang and Speedtest) and in addition uses data from the WiFi physical layer in order to gather a comprehensive set of WiFi network performance metrics. 

For more information, please explore the wiki tabs to the left, or visit the GÉANT WiFiMon service page.



WiFiMon Operation Modes

WiFiMon can operate in two different modes which
can be used either separately or together


SW

Software Crowdsourced Measurements

Measurements are gathered from users' mobile devices (phones, laptops, tablets, etc.) while they use the network. This approach does not require any additional software to be installed on the mobile devices. Measurements are recorded while the end users use the network and impose the a minimal additional network overhead. Crowdsourced measurements capture the subjective perception of the WiFi network quality of service and responsiveness.

HW

Hardware Probe Measurements

Measurements are gathered from the dedicated small form factor hardware devices (currently Raspberry Pi’sPi devices). Fixed WiFiMon measurements capture the objective measures measurements of WiFi network quality (signal strength, link quality, bit rate etc.).



WiFiMon Features


Technology and vendor agnostic

WiFiMon can be deployed on any WiFi network as it monitors the performance on the network layer. It can also provide additional benefits in 802.1x enabled networks including eduroam in which case the users can make various performance analyses per access point, per user, etc.

Fine grained information on network performance

WiFiMon shows the end-user (mobile client) behavior behaviour on a network, its perception about the responsiveness of the network and the speed of web resources downloadresource downloads, correlation of the performance data with end-user data, and data analysis with an effective query builder. 

Easy to deploy

WiFiMon is a software image (also available as an a Docker - Image) and can be easily deployed on an NREN/University network on hardware or software probes.


Active monitoring with low network overhead

WiFiMon active measurements are not significantly invasive and do not use too much of the available any significant bandwidth. One WiFiMon measurement is comparable to one average web-page download (load speed).
