Wonder if you could do point to point laser comms.
- kragen 4y agoUS military radios use FHSS spanning 225-420 MHz. I don't know details but I bet they're hard to jam or even detect.
- bob1029 4y agoDSSS/FHSS schemes are almost magical in LPI and resilience when applied aggressively in a military setting. Operating below the noise floor shouldn't be possible at first glance, but through the power of statistics it absolutely is feasible.
- kragen 4y agoHmm, I notice you mention LPI and resilience but not LPD (low probability of detection). Is DSSS maybe easier than FHSS for an adversary to detect on a waterfall plot and localize with phase correlation if they have a phased array? Or is it also suitable for LPD?
- RF_Savage 4y agoOr 36-87MHz. And plenty of others.
