That is, don't bother with wireless meshing if you can avoid it. A single 802.11 channel won't sustain that many clients, much less the meshing OLSR traffic. So, say 10 nodes spaced evenly throughout the conference venue, where immediately adjacent nodes are set to furthest possible channels (e.g channel 1 and 11). Apply similar reasoning for dual-band access points; adjacent devices need to not have their radios on adjacent frequencies.<br><br>Also, you probably will want to turn the TX power on each node <i>down as much as possible</i>, as they will be operating in a very noisy environment at close spacing. RX sensitivity is preferred over trying to drown out noise with TX power. <br><br></div>Finally, you'd want generous RAM available on the access points, so that the firmware can service many clients. Something like UBNT Rocket M2 (64MB RAM), UBNT UniFi AP (64MB RAM), or even TP-Link TL-WDR4300 (128MB). The UBNT stuff would permit easier mounting on walls/poles, since the TP-Link is only an indoor consumer-grade unit.<br><br><br><br></div><div class="gmail_extra"><div><div class="h5"><br><div class="gmail_quote">On Fri, Mar 20, 2015 at 10:32 AM, Adam Longwill <span dir="ltr"><<a href="mailto:adam.longwill@gmail.com" target="_blank">adam.longwill@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">There will be issues with any device accepting more than 35 connection requests at a time due to the nature on 802.11 in general.

<p dir="ltr">Commotion is is OpenWRT with some configurations and OLSR running on the mesh interface which will reduce airtime overall. If anything, you should mitigate this by having multiple radios on multiple channels with ethernet meshing instead of a wireless mesh interface.</p>
