We will probably have devices with dual band radios also, but right now I choose to use three 2.4Ghz radios because this is way we get capacity for more people and these wifi routers are much cheaper than dual band. Most client devices are still single band, only premium devices have dual band chips, and my rough estimate that that is around 10% od devices... so currently it makes little sense to for dual band, better to have two or three radios and have more capacity. In refugee situation as one we were involved in there are lots of people, we worked in refugee camps which had capacity of 2000 people and on most days they were full. So having dual band radio who would have nice but we were on a almost no budget and providing and for same amount of money you can get more 2.4 routers than dual band routers... and it is a question how many people would benefit with 5.8 radios... And TP-LINK WDR3600 and WDR4300 boards are quite bit larger that WR841 boards and I'll have to see if that even makes it possible to 3D print whole case... This first version we are developing will have only 2.4Ghz radios and next one will have dual band radios as well... Awesome, thanks! AR9331 datahseet is easily found online but AR9341 or QCA9533 or any other datasheet is not, strange...

Hi Charles, your Freedom Tower was the inspiration for building first towers in refugee camps... To get a bit of background I recommend you check out this article: https://medium.com/@mesh_point/how-the-refugee-crisis-gave-birth-to-a-cool-… On Mon, Jan 11, 2016 at 2:35 AM, <charles(a)thefnf.org> wrote: Yup, we will use dual band routers in next release, for now we will have three radios, by default they will all be in both AP and mesh mode so they will connect with neighbouring routers if present. We will test this setup versus pure AP mode on devices to see if it makes any difference in performance if we switch off virtual mesh interface, we are also considering not having mesh interfaces on by default but to be turned on only if needed. In Slavonski Brod we setup wifi routers on 20m high light poles (that was an adventure): https://www.facebook.com/OtvorenaMreza/posts/944652762273651 Each light pole had one Nanobeam M5 that was connected to uplink side which was 3km outside the camp. Nope :) We don't have anything in refugee camp. 3D printer in in our hackerspace #labOS in Osijek, 100km away from refugee camp. We are using 3D printing for now because that is our only option during prototyping, but we have contacted different manufacturing companies that can deliver plastic parts via thermal forming or injected molding techinques. We willl probably do a combination - thermal forming for exterial case (around 20€ per piece) and 3D print top and bottom plate (20€ - around 10€ per plate). Plastic injection molding makes only sense for over 500 pieces... We are using Wlan Slovenia firmware, check it out at https://nodes.wlan-si.net/ we are using Nodewatcher V3 from guys from Wlan Slovenia. AFAIK this is the most advanced software for building and managing community mesh network... I know :) Wha is currently happening with FNF? I googled you a few months ago and it seamed like project was dead... no updates whatsoever...
