There is a similar topic which got closed Mesh distance between devices So I am starting a new one. This link is more about how many devices to have to cover an area. [image] Ratio of mesh-only (Xenon) to internet-enabled boards (Argon, Boron) BLE // NFC What ratio do y…

Thanks for re-opening this topic/opening a new topic and sharing your findings. My particular interest is a Business Office/School/University environment and my initial results (using the macro:polo test code and monitoring via the console for missing devices) indicate much shorter distances even w…

@rocksetta , to better represent range, your circle boundaries should overlap at their centres. This represents the node-to-node maximum distance: [image] This “matrix” configuration follows the optimal 4-neighbour arrangement for redundancy. By filling in the intesticial spaces will allow each n…

Nice diagrams @peekay123 , that makes a lot of sense. Still Dmax is variable based on the landscape (walls, metal, concrete etc) and decreasing Dmax will probably strengthen your network stability, but dramatically increase your number of devices. By the way, has anyone done a line of sight effect o…

@rocksetta , agreed regarding Dmax. However, my point was that mesh topology planning is crucial to a successful mesh deployment. My interest is in separating the mesh connectivity from the Cloud connectivity for testing. Characterizing mesh antennas (eg. duck vs pcb) is important as well. Your a…

[image] peekay123: BTW, I have asked Particle if they could come up with a suite similar to marco-polo for mesh testing. It would be interesting to know not only the distance a node can remain connected at but also what data rate is achievable at that distance. Really good point. Shouldn't w…

@rocksetta , a mesh pub/sub would need to be time-characterized with various fixed payloads. Knowing the average pub-recv-pub-recv transaction time, an estimate of single-leg (eg. gateway to node) can be calculated and plotted. Another approach is to not use mesh pub/sub and do UDP directly from a …

Good article about what effects the range http://www.pearsonitcertification.com/articles/article.aspx?p=1329709&seqNum=3 Interesting chart on the page and this summary Physical objects: Trees, masonry, buildings, and other physical structures are some of the most common sources of interference. T…

[image] rocksetta: could a mirror or sheet of aluminum foil strategically placed inside a building reflect a signal around a major RF blocker! Most likely not but it would be the typical location for a repeater node.

Typically people attenuate wifi signals and because they move around that makes the attenuate dynamic and thus difficult to plan a mesh topology for - this is where the mesh repeater devices come in. I think you are onto something with the WiFi coverage design tools - I have seen a very good one fr…
