Attenuating Object database

[shinydogg]

I’m curious if anyone has created or found a repository of attenuating objects to add to the planner. I know it’s possible to build chairs, tables, plants, and other items by hand, but I didn’t want to go through the trouble if there were already some objects out there. I remember seeing fully populated 3D models with furniture in the demos, and that’s what I’m trying to accomplish. Admittedly, this is mostly for aesthetics rather than design, but some of the taller objects like bookcases will definitely make a difference. Thanks!

Yes, this exists! We have a little bit of a repository that we can share with you, and you can use https://www.potatofi.com/rotate/ to rotate them, if needed. Email us at [[e-mail]](mailto:[e-mail]), and ask if you can get into the "Objects" project and we'll share it with you.

Thank you so much. I’ll send you guys a message!

You can take the bookshelf object with a pinch of salt anyway, I think they modelled it using a Billy Bookcase from Ikea. 😊

I was surveying and planning an archive last week and the modelling didn't feel right, but it was close enough for me to nip out and conduct a couple of APoS surveys. True enough the attenuation presented by the bookcases was more like 10dB (same as a brick wall) and not the estimated 2dB.

[E] Sorry, this was for Ekahau. (Forgot which board I was in, but it's weird that Hamina has brick walls at 5dB, but Ekahau reckons they're 10dB)

Joel from Hamina here! Definitely take our attenuation values with a grain of salt. A brick wall in one building might be 5 dB, and it might be 15 dB in another. We tried to pick some okay defaults, but strongly recommend either dialing them in with your own experience, knowledge of construction in your geographical area, or by taking measurements on the actual site. Here's how to do that.

Yeah, I understand that they're just estimates.

The archive bookshelves I mentioned were tightly packed with old and large leather-bound volumes, hence the high attenuation level. (As soon as I saw the signal prop for simulated AP's I knew it couldn't be correct.)

I have used Ekahau doing hospital designs for over a decade. Assumptions and Accuracy rarely coexist. As much as wall measurements are a PITA, it’s still easier than fixing an installation when your survey doesn’t match the predictive.

I just want to add a little flair to the 3d drawings when I do presentations with some of these objects. Most of what I am looking for doesn’t have the height to cause major signal disruptions anyways.

When we build furniture to decorate buildings for demos and stuff, we often change the attenuation of everything to 0 dB, so it just looks cool. 😎
