1. WIND Milosz Hulboj Vlad Lapadatescu

2. CERN’s campus

3. Number of deployments: increasing Number of users: increasing User demands: ever growing Available spectrum: shrinking! CERN’s campus

4. Timeline 2010.02 – Project started 2010.08 – Visit in HP Montreal 2010.11 – Technical report, change of scope, first collection system, initial performance metrics 2011.11 – Radio channel counters added by HP, change of scope 2011.12 – First rule based diagnostic engine 2012.10 – Technical report, findings, deliverables 2012.11 – Visit in Canada, knowledge transfer 2013.01 – WIND as a tool for network engineers

5. Global perspective of WLAN deployment

6. User perspective of the network (with history) Remote diagnostics List of probable problem causes Broad range of problems detected Assessment of WLAN health: – Reduced number of site surveys – Proactive monitoring (interference, rogues) – “What-if” analysis – Without probes! WIND saves time, resources and money!

7. State of the art WiFi monitoring and diagnosis tools Extensive feedback to WiFi Service manager Valuable feedback to HP Two technical reports, procedures, suggestions, know-how WIND as a service for WiFi monitoring and troubleshooting WIND’s legacy

8. Big thank you to HP for an excellent collaboration Big thank you to CERN CS group for: – tolerating our experiments – help and ideas provided – testing of our tools Acknowledgements
