Serval Mesh(android) &Serval Chat(ios)自建局域网聊天传文件打电话

Serval Mesh is the Serval Project’s flagship product. It is a free and open-source app for Android 2.2 “Froyo” and later, under continuous development. The latest official release of the Serval Mesh app is freely available from Google Play.

Serval Mesh allows people to make voice calls, send text messages and share files with other Serval Mesh users, without requiring infrastructure like satellites, cell phone towers, Wi-Fi hot spots, or radio repeaters. The primary motivation is to provide resilient communications during crisis and disaster situations, when vulnerable infrastructure like phone cell towers and mains electricity are cut off. Serval Mesh is also useful for remote communities who lack conventional telephone services, small organisations who need an internal telephone system, and dissidents in oppressive countries that deny or monitor their citizens’ telecommunications.
