Anti-jam communications for drone swarms
Jamming defeats the radios that fly today's drones, and fibre tethers, autonomy and anti-jam antennas don't let a swarm talk to itself. Reach gives every drone a short, collision-tolerant link that hops to a new frequency every burst and can trade speed for jam resistance, so the swarm keeps talking to itself.
Key results
- ~50× jammer power survived at the most robust setting, even if the jammer follows the link; about 2,500× while hidden and hopping (analysis)
- ~4× the traffic of a Wi-Fi-style network at light load in a 10-drone swarm, mostly from longer reach
- 84% of traffic still flowing after losing 3 of 10 drones, if routes are rebuilt instantly
- <3 ms per 58-byte control message in a 500 kHz channel
Narrowband jammers (tones and sweeps) are removed outright in testing up to about 50× the signal, and the swarm keeps a shared clock without GPS. Simulated; frequency hopping is not yet built.
