Which of the following statements with regard to drone swarms is/are correct?
- They use Terahertz band of frequency to communicate with the command centre.
- Individual drones in the swarm can communicate with other drones in the swarm.
- GPS Spoofing is a commonly used technique to counter drone swarm attack.
Select the answer using the code given below:
Correct answer: B
Explanation
Drone swarms use mesh networks where individual drones share data with peers and adapt collectively, so statement 2 is correct. GPS spoofing — feeding false navigation signals — is a standard counter-swarm electronic-warfare technique alongside jamming and directed energy (3 correct). Statement 1 is wrong: swarms typically use sub-6 GHz RF, Wi-Fi, LTE/5G or proprietary bands, not the Terahertz band, which suffers severe atmospheric attenuation and is still experimental. Hence 2 and 3 only.
