Hardware Description

1. Adopt domestic self-organized intellectual property technology, private network, private communication transmission protocol, and unique synchronization code.
2. AES 128-bit encryption technology: After the information data is encrypted by AES, the information before encryption cannot be obtained;
3. Using multiple encryption methods and modular design;
4. “Wireless Mesh Network”; no center, distributed, all nodes have equal status, and can form a self-organized network under complex conditions such as shielding non-line-of-sight (NLOS) and high-speed movement, and realize TDD two-way communication;
5. It supports any network topology such as point-to-point, chain, star, mesh, and hybrid, and can realize real-time interaction of multi-channel IP-based clear voice, broadband data, high-definition video, and other multimedia information;
6. In the same-frequency sensing network (under improvement), multi-hop relay, each node can move randomly and quickly, and the routing can be dynamically reconfigured when the system topology changes rapidly;
7. Convenient deployment, flexible use, simple operation, convenient maintenance, and all-IP design (supporting various data transparent transmission) make it easy to realize the interconnection and intercommunication of heterogeneous systems, especially suitable for wireless coverage transmission and wireless video surveillance;
