<div dir="ltr">Hi Ben,<div><br></div><div>Thank you for your feedback. We will review our overall deployment design.</div><div><br></div><div>Here is some additional information. We will build a customized node. The prototype is using a dual core ARM cpu with 2GB ram, gigabyte Ethernet as <span style="font-family:arial,sans-serif;font-size:12.666666984558105px">wired backhaul</span>. We will hookup USB WiFi dongle to service the clients. </div>
<div><br></div><div>We do plan to test wireless backhaul and probably run it on <span style="font-family:arial,sans-serif;font-size:12.666666984558105px">5.8GHz radios.</span></div><div><span style="font-family:arial,sans-serif;font-size:12.666666984558105px"><br>
</span></div><div><span style="font-family:arial,sans-serif;font-size:12.666666984558105px">Right now the design call for each node to support 30 to 50 clients. We will try to find out what kind of usage scenario is possible. Data only? with voice? with video? How will transfer large data affect the performance?</span></div>

<div dir="ltr">My recommendation, from operating a mesh network with firmware very similar to Commotion, that serves ~100 people daily, would be to focus on how many mesh nodes you would need to deploy. Likewise, since there is no way to fit 2000 users on a single 2.4GHz channel, you would be needing to segment such a large deployment into pocket meshes, e.g. a handful of nodes in each mesh, with adjacent meshes programmed to non-overlapping channels. Backhaul between these pocket meshes could be done with 5.8GHz radios, or wired backhaul depending on your situation.<br>
<br>To help with estimating how many nodes you'd need, it's fair to assume each node could only support up to 5 (or possibly 10) simultaneous clients before either the node itself exhausts its RAM (only 32Mbytes onboard memory) or before the particular channel used by that ( node + its neighboring nodes + all clients ) becomes saturated.<br>
