The meeting was a session of the WLANPros Wi‑Fi design class, focused on predictive design in Hamina and practical Wi‑Fi considerations. Ferney addressed confusion about the meeting time and shared temporary Hamina licenses with attendees. The group discussed venue costs for a Manchester training and possible alternatives, and alex offered a potential venue in Brazil. Ferney demonstrated Hamina features, including slab-only attenuation, client height, and the use of survey data to inform design. There was extensive discussion on offsets, device variability, and the limitations of predictive vs. measured surveys, with input from Glenn, Martin, Walid Abdelkader, and others. The session covered primary and secondary coverage, AP placement, auto-planning, channel settings, and the impact of obstacles and multi-floor bleed. Ferney emphasized designing for the weakest client device, the importance of redundancy and roaming, and the unreliability of active throughput surveys. The class also touched on real-world examples, such as senior care facilities, warehouses, and stadiums, and compared Hamina, Ekahau, and other tools.
Chat Notes:
00:30:15 simon: if floor 2 is 5m and the rest is 2.5m, will the walls that is set for ceiling height, is it 2.5/5 or according to the respective floor?
00:30:28 Hiten J. Thakkar: If I am not mistaken Kjeiel (must have butchered his name – sorry) has created skills for Hamina to add furniture and other stuff. He had a whole blog about it and is active on WLAN Pro SLACK but verify
00:34:48 alex wirz: Easy peasy. the one issue is hamina don t allow me to rotate, so I created 2, 1 for horizontal other for vertical
01:05:12 Mark: in stadiums, on gameday testing, the signal varies based on holding the phone on your lap sitting down or holding it up near your chest or face.
01:06:34 Ned Neece: Another major issue, if stadium is surveyed empty and not surveyed on game day.
01:09:19 Ned Neece: Looks funny! 🙂
01:10:47 Mark: Show the client the pretty one with some margin for safety
01:13:08 Johan Daniel Aponte Quiñones: That where I get signal from on the neighborhood
01:45:01 Hiten J. Thakkar: Be prepare to butt heads with the contractor will not follow the recommendation of your predictive design and will change the installation points without informing and especially when they install AP next to the Fire Sprinklers. This always happens when a University does a capital project same issues different contractors.
01:45:56 Hiten J. Thakkar: Never do stack, go with honeycomb that way you can take advantage of co-channel sharing
02:05:57 Alain: Wi-Fi Client Testing
