If a #reticulum #meshchat instance with a #lxmf address on one computing device has 4 identical #lora #rnodes #rnode interfaces, each with same settings of frequency #spreadingfactor #sf, each rnode having a #directional #yagi #antenna in close vicinity, will transmission to a sender of a #deliveryconfirmation (#downlink) from 1 antenna to the sender's direction, be messed up due to local #collision at rnode 1 of different attempted #acknowledgement signals of the other 3 near rnodes?

Is there a #simulation of a #lora #reticulum #radio #mesh used with different numbers of #rnode #radio #nodes #rnodes for given #spreadingfactor ( #sf ) & given payload size? Am interested to know what happens to the routing, & likelyhood of #deliveryconfirmation for small LoRa packets (max 2 blocks), for longest transmission times i.e. spreading factor 12 #SF12 . Would like to know if my impressions, that SF 12 is very tricky under #RNS LoRa as compared with #SF10, have a clear explanation.

Some interesting info about the effect of #spreadingfactor (#SF) in #lora #radio #mesh is in papers about SF https://pmc.ncbi.nlm.nih.gov/articles/PMC8512894 SF12 in #lora & lora https://pmc.ncbi.nlm.nih.gov/articles/PMC5038744

Can one influence the effectiveness of using multiple #rnode interfaces , in one single end-point location, with different SF by setting the #LXMF delivery limit #DELIVERY_LIMIT down https://github.com/markqvist/LXMF/blob/c426c93cc5d63a3dae18ad2264b1299a7ad9e46c/LXMF/LXMRouter.py#L38 from the default 1 MB for those #rnodes, of a set, with higher SF values?

In a world where control of #communication networks is increasingly centralized, #DIYnetworks offer an independent alternative. This presentation shows how to build up your own autonomous #meshNetworks with low-cost hardware components and open source tools such as #Reticulum and #MeshChat. We will present practical steps for the construction, configuration and integration of sensors, communication and computing power. We are also discussing how such #networks can be used in #humanitarianCrises, such as the organisation of aid measures through solidarity initiatives.

This workshop offers a detailed journey through the world of do-it-yourself radio networks and #autonomousCommunication structures. Using an exemplary system structure, we show how to realize cost-effective, flexible mesh networks with #LoRa #RNode, Reticulum and MeshChat. In doing so, we not only dedicate ourselves to the technical requirements – such as the optimal hardware selection, antenna adaptation and network planning (keyword “Network Planning 101”) – but also consider how these technologies can be used for #humanitarian purposes, for example at #CADUS.

Any recommendations for a 64 bit machine for #proxmox to run 8 dedicated #virtualmachines #vm each running minimal #ubuntu for a single #reticulum #meshchat application with 8 single usb-c connections to 8 #lora radio #rnode #nodes like a RAK4613 https://store.rakwireless.com/products/wisblock-meshtastic-starter-kit?variant=4388403462163
Here is what their site says: https://www.proxmox.com/en/products/proxmox-virtual-environment/requirements
Requirements for each VM is not much more than 1 Gb and storage requirements trivial (less than 30 Gb per machine). Any recommendations most welcome.

If I have 10 virtual machines (m1..10) in #proxmox each running #rnode hardware (r1..10), via 10 #meshchat guis (g1..10), over one of 10 respective usb-c connections,
& all 10 virtual machines are on the same local area network #LAN via 1 network card/interface of the 1 computer running proxmox, can I link the virtual machines using #reticulum #rns #autointerface
https://reticulum.network/manual/interfaces.html#auto-interface
& will thereby each #rnode #meshchat #gui receive all #lora mediated data from each other #rnode over #lan ?

Which is the lowest cost, #reticulum compatible, #rnode hardware for #lora radio?

Web #pages , including #webcam #images , can be served by a #lora #radio #rnode using #reticulum #nomadnet over a #lora #radio #mesh , and accessed via #meshchat over the lora reticulum mesh using a mobile rnode :

To receive by #radio #reticulum #rnode #announces on #lora radio one needs to have the same 4 radio parameters as the announce: #frequency #bandwidth #spreadingfactor SF #codingrate CR
-> #meshchat permits any number of #rnode interfaces !
To hear the most announces, does it make sense & is it possible to set up several e.g. 5 #lora #radios with same frequency: 869.525 MHz
bandwidth: 250 kHz but
each with different SF & CR? Would one be able to receive more announces that way? Would it work?

A #rnode build for #reticulum using a #raspberrypi5 and #geekwormx1206 #ups for a #carnode or #solarnode
https://www.loramesh.org/subpages/upsrnode/upsrnode.html
Running #meshchat , four #liion #21700 5000 mAh batteries seem to run the #rak4631 and Pi for at least 24 hours. The device can be re-charged using #usbc or 9 to 18 V DC at up to 3 A via a jack or other connector. The rnode shuts down cleanly when batteries run out & re-starts when power is back, whereupon the batteries charge at the same time in #passthroughcharging

#lora #radio #reticulum using #meshchat
If one #rnode (rnodeA) run by device A, e.g #RaspberryPiZero2W , has is its own #wifi #hotpot (as shown here https://loramesh.org/subpages/pi_install.html#pi_hotspot) (with SSID & password),
& another rnode (rnodeB) run by another device B (any device with wifi) joins the hotspot (SSID & pwd),
& rnodeA & rnodeB both have the 'default interface' activated in their reticulum meshchat GUI,
the wifi hotspot *alone* (without radio) will enable sending messages via reticulum between A and B !

@tomjennings @Mark @phanuel @goldfishlaser Using #reticulum in #lora only #mesh using #meshchat application. It is beyond fantastic. No issues. Excellent delivery confirmation. Sends #images & #sound. When on the move with #rnode it resends messages, that failed due to no radio contact being available at the time of send, & sends them automatically later when in lora radio contact. Even re-sends chunks of images in batches as & when in lora contact again. Fab! Info: https://loramesh.org
