All the information you seek is found in the article you stubbornly refuse to read.

having read that meshtastic section: I mostly agree with their requests tbh. the only suggestions in there seem to be "use full duplex" (with approximately one reason why, though it's a good one) and "solve frequency discovery with SDR" which they've already addressed as somewhat ridiculous - because it is, for someone interested in a low power and low cost network.

particularly the SDR stuff, which is the VAST majority of that section. this is not at all the same target audience as meshtastic:

>A computer with “sufficient” compute power and RAM, to run the ka9q-radio software. KA9Q has stated that a Raspberry Pi 4 is sufficient, and now we have the Raspberry Pi 5 with up to 16 GB of RAM, for only $120.

that's like suggesting the way to fix a wireless problem is to use a wire. otherwise the criticism seems to summarize as "it's slow and bad" and well. okay? that's hardly constructive, whether or not it's accurate.

the whole thing reads like "the solution is left as an exercise to the reader ;)" because it sounds like it's written by and for people who are already experts and just want to read a cathartic list of flaws they already know. and/or "buy better hardware lol". it's not at all the logical slam-dunk that you seem to think it is.

		Meshtastic can only use one frequency at a time. So, say, a battery status update can stomp on a message trying to get to a meshtastic router. (He's got the link to the hidden node problem with a great wikipedia article about it). The more popular the network, the more frequent these message stomps happen. Flood routing makes these stomps more frequent. There is also no end to end packet acknowledgement system like tcp, so at hop 3 (e.g.) if the message got stomped on, who would know? Let's say someone made a dual band lora transceiver. Well that would help, but it wouldn't solve anything else, because there's still core routing/reliability/topology issues. So if you had 20 channels to talk over, well that would be even better. The chance of having your message stomped on would go down significantly making the network much more reliable. That's the SDR part (the listening of 20 channels at once) vs the Lora chip which can only listen/transmit on 1 channel at once.
