including AJ (Anti-Jam) model and CC (Covert communication) model;
* AJ model, using PLS (Physical Layer Security) mechanisms, not only provide high-bandwidth audio and video transmission, but also offer LPI (Low Probability Interception) spread spectrum communication capabilities to resist malicious interference.
* CC model, while maintaining low transmitter power, leverages the secret methods of modern infrastructure to enable covert communications between units. It is particularly suitable for urban operations with diverse terrain obstacles.
