Rapidly Deployable Satellite Communications for Emergency Situations: the WISECOM Trials
This paper presents a general overview of the WISECOM (Wireless Infrastructure over Satellite for Emergency Communications) system, focusing on the trials performed on a specifically developed demonstrator during a live simulation of a disaster event. The WISECOM system is intended to rapidly deploy a complete communications infrastructure in the early hours after a disaster occurs through the ...
متن کاملCommunications in Emergency and Crisis Situations
In emergency and crisis situations (ECS) like earthquakes, tsunamis, terrorist attacks, it is very important that communication facilities are operative to provide services both to rescue teams and civilians. In ECS it is very common that communication premises are often unable to provide services, either due to physical damages or traffic overload. In such a case there is the need for rapid re...
متن کاملOn the role of satellite communications for emergency situations with a focus on Europe
In this paper, we describe how satellite communications may contribute to disaster management. During emergency situations, satellite communications present many advantages in supporting or replacing a terrestrial infrastructure (if any) subject to destruction or saturation. However, devising the right deployment model deserves close scrutiny in order to fit the responders’ needs and sustain fi...
متن کاملSatellite imagery analysis for operational damage assessment in Emergency situations
When major disaster occurs the questions are raised how to estimate the damage in time to support the decision making process and relief efforts by local authorities or humanitarian teams. In this paper we consider the use of Machine Learning and Computer Vision on remote sensing imagery to improve time efficiency of assessment of damaged buildings in disaster affected area. We propose a genera...
متن کاملAdaptive Beamforming for Acoustic Communications
The basic factors which need to be considered in the design of a practical through water communications system utilising an adaptive beamformer at the receiver are examined. Simulation results demonstrate the feasibility of using such a scheme. It is clear that the multipath phenomenon which has proved so detrimental to a high data rate through water communications link may be effectively count...
