当网络与信号中断时，如何保持联系与信息流通

⸻

🔹 近距通讯 • 对讲机（VHF/UHF）：2–10 公里，设固定频道，可中继扩展 • Mesh 应用：Briar / Bridgefy / Meshtastic，通过蓝牙或 Wi-Fi Direct 传讯

🔹 中长距通讯 • 短波电台（HF）：跨省跨境，需天线与电源 • 物理传递：U 盘 / SD 卡 / 蓝牙，在市场或学校定点交接

🔹 社区联络 • 固定时间频道：如每天 19:00 • 公告板：市场、学校、清真寺 • 信号约定：灯三闪=紧急，三声=集合

🔹 个人装备 对讲机＋备用电池｜移动电源或太阳能板｜离线地图｜纸质通讯录｜U 盘

🔹 心理与文化 集体祷告、夜间围炉、口耳传讯维系信任

⸻

📌 三原则 1. 去中心化：不依赖任何网络 2. 多渠道：电台＋离线＋面对面 3. 提前演练：习惯先于危机

Translation: When networks and signals go down, how to maintain connection and information flow

⸻

🔹 Short-Range Communication • Walkie-talkies (VHF/UHF): 2–10 km range, fixed channels, relay extendable • Mesh apps: Briar / Bridgefy / Meshtastic via Bluetooth or Wi-Fi Direct

🔹 Medium & Long-Range Communication • Shortwave radio (HF): inter-province or cross-border, requires antenna and power • Physical transfer: USB drives / SD cards / Bluetooth, exchange points at markets or schools

🔹 Community Coordination • Fixed broadcast times (e.g., 19:00 daily) • Bulletin boards at markets, schools, mosques • Signal codes: three flashes = emergency, three tones = assembly

🔹 Personal Equipment Walkie-talkie + spare batteries | power bank or solar charger | offline maps | paper contact list | USB drive

🔹 Psychological & Cultural Resilience Group prayer, night gatherings, oral transmission to maintain trust

⸻

📌 Three Core Principles 1. Decentralization: rely on no single network 2. Multi-channel: combine radio, offline, and face-to-face methods 3. Preparedness: practice before crisis
