When disaster occurs, hurricane for example, it causes serious human injuries and deaths. Some deaths own to structural collapse or flying debris, which is the direct deaths. Others may die from the condition that happens following the disaster-like difficulty communicating during the emergency. Hurricane destroyed most of the base stations and mobile phone towers. If a person suspects heart attack, there are no telephone signals to call 911. So, losing a working communication structure would not offer the assistance in time and save life. TBSs (Temporary Base Station) can act as temporary cellphone tower, providing signals for emergency call
