That’s actually what makes LoRa meshes interesting here - the chirp spread spectrum is genuinely hard to jam without wideband power, and the ISM bands they ride on (433/868/915 MHz) are too economically important for a state actor to blanket-jam without taking out IoT, logistics, and industrial telemetry as collateral. The asymmetry flips: jamming costs them more than it costs you.
lora bitrate and radiated power are tiny and such considerations are only important in peacetime. gps is jammed now routinely and it’s more important than 95% of iot dogshit. telemetry and remote control that matters is either wired or has reserved separate band, like power grid switches. not sure wdym by logistics
you also have to be stealthy and if you emit you’re seen and if you’re seen you’ll be found and soon dead. lora doesn’t help you with that especially if you increase power to overcome jamming. using starlink in iran now for example is a capital offense. last time i’ve checked, irgc ew looks for starlink wifi and they can find it even if it’s renamed because of its distinct signature. it takes less to spot lora. they do not look for uplink for some reason but they try to jam it and downlink too

Those are very valid points. Thank you
