After strong earthquake

the local field communication network facilities are often damaged

so quickly establish effective emergency communication network coverage

delivering timely disaster information is of great significance for the rescue work such as disaster relief organization and command scheduling

etc.Wireless networks because of its technical characteristics

such as simple

rapid

low cost

are very suitable as the platform of on-site emergency communication network.This paper puts forward a method for earthquake field emergency communication based on wireless Mesh network

that is using wireless Mesh network technology rapidly to form a wireless LAN at the scene of the disaster area

so as to realize information transfer and sharing in the disaster zone.The whole system network is fast and good robustness.With using satellite communication technology

all of local area network can be composed of a wide area network

and access to the Internet.This method can meet the basic requirements for information transmission of the emergency scene.
