Emergency Response and SDR Communication
In emergency scenarios such as earthquake rubble, flood-stricken areas, and mountain forest rescues, traditional communication systems (public/private networks relying on base stations and fiber optics) often face the following issues:
1. High Dependency on Infrastructure: Once base stations or fiber optics are damaged by disasters, the entire network can be directly interrupted. For example, after an earthquake, public networks in main urban areas may be paralyzed, preventing rescue teams from communicating in real time.

2. Slow Deployment Speed: Rebuilding base stations requires transporting equipment and debugging lines, taking at least several hours or even days - far too long to keep up with the"golden 72-hour rescue window."

3. Significant Coverage Limitations: In complex environments like mountainous areas or rubble, traditional signals have weak penetration. Rescue teams often lose contact after entering deep into the disaster area.

SDR Communication Directly Address Emergency Communication Pain Points
1. Non-centralized Architecture: Eliminates dependence on base stations; networks form immediately upon powering on. After earthquakes or floods, there is no need to wait for infrastructure repairs. Rescue teams can form a network upon arrival with their equipment, solving the core issue of"disconnection without base stations."

2. Self-Healing Capability: Link remains uninterrupted even if a single node fails. If a portable SDR carried by rescuers is damaged by falling rocks, remaining SDRs automatically switch relay paths, ensuring uninterrupted voice and video transmission between frontline teams and the command center, preventing a"single point of failure."

3. Flexible Deployment: Lightweight and adaptable to multiple scenarios. Mountain rescue can use UAVs (drones) as relays to cover valley blind spots. In rubble rescue, team members can maintain close-range coordination using portable SDR, solving the traditional communication problem of being"unable to penetrate complex terrain and provide adequate coverage."

4. Low Latency + High Reliability: Ensures delivery of critical commands. Frontline rescuers can transmit real-time video of trapped individuals from within rubble, enabling the command center to quickly formulate rescue plans based on the footage and avoid missing opportunities due to information delays.
