Background
UNICEF, who focuses on providing assistance to women and children in developing and undeveloped countries, emphasis on helping people in emergency natural disasters. Under the life and death situation, communication is one of the most critical things needed. In order to effectively respond to natural disasters, UNICEF has to select the best type of communication and network at the current time. UNICEF also has to concern about many factors. For example, the local network of the affected area is probably destroyed, and it may not have been reconstructed shortly. The help and sources from local area may not enough. These constraints can be worked on by the communication methods. Assuming that all kinds of power went off,

Fast data rates and extended coverage, flexible allocation of radio signals, low power consumption, data-casting and audio and video streams, and channel switching are all benefits of WiMAX and WiFi which are critical for natural disaster communication (Certain & Liu, 2013).

The second type of innovation technologies that should be considered when a natural disaster strikes is called “mesh” which based on solar power. Nilanjan Banerjee, assistant professor of computer science and computer engineering of University of Arkansas told that “The ultimate goal of this project is to save human lives…..Deployment of this system could warn people to get out of harm’s way and could help emergency services personnel reach victims much faster. This last part is critically important because we know that many deaths occur in the minutes and hours after a disaster strikes.” The concept is that the mesh works as a network of nodes that blanket a geographic area. Each solar-powered node contains data, geographic information that users can download, while node-node communication is also available if necessary. The further function is that the mesh will automatically redistribute data to maintain service, when nodes fail because of variability inherent in renewable energy of the likelihood of extreme environmental conditions after a natural disaster (Banerjee, 2012).
The benefits of the mesh system are various. It will provide continuous, uninterrupted service
