ALTERNATIVE COMMUNICATION SYSTEMS DURING DISASTERS

PSTN or the public switched telephone network is the prime network responsible for transmitting and receiving voice, fax and data. All government and private offices, police stations, fire stations, hospitals and majority of homes and business places are serviced by the PSTN line.

. Amateur Radio operation does not use ground based infrastructure. Moreover these have limited power needs which can easily be met by batteries and generations. Therefore, it has been experienced that Amateur R ....etc

If you were to ask a dozen different amateurs what ham radio meant to them chances are you would get 12 different answers. Amateur radio operators are often called ham radio operators or simply hams and frequently the public is more familiar with this term than with the legal term Radio Amateur. The source of this nickname is for all practical purposes lost from the beginning.

ABSTRACT

The demand for high-capacity wireless services is bringing increasing challenges, especially for delivery of the last mile . Terrestrially, the need for line-of-sight propagation paths represents a constraint unless very large numbers of base-station masts are deployed, while satellite systems have capacity limitations. An emerging solution is offered by high-altitude platforms (HAPs) operating in the stratosphere at altitudes of up to 22 km ....etc

A human being presence detection system automatically determines the presence of human beings without directly attaching sensors to the human body and detects human drowsiness.human beings are detected using data obtained from pressure transducers in the space of interest.The pressure signals are processed by a novel signal processing algorithm to determine the presence or absence of a human being. different types of pressure transducers are used. It can be used for the rescue of military personnel or of persons trapped under rubble of earthqua ....etc

An emergency communication system (ECS) is any system (typically, computer-based) that is organized for the primary purpose of supporting one-way and two-way communication of emergency messages between both individuals and groups of individuals. These systems are commonly designed to integrate the cross-communication of messages between a variety of communication technologies, forming a unified communication system intended to optimize communications during emergencies. ....etc
