Ans. 1. In case of any major disaster or emergency situation, it is extremely necessary to have the communication links operational among Government authorities at various levels and the volunteers working in the disaster affected areas to help the affected population.
2. It is necessary to ensure that the critical needs to search and rescue operations, relief and response measures are communicated among the authorities of State Government, local administration, voluntary organizations and the affected population. So, reliable alternate communication links are necessary which ensures the rapid movement of the right resources to the right place at the right time.
3. Sometimes, some severely affected areas get completely disconnected from other parts of the world. So alternative means of communication can connect these areas with the rest of the world.
radio, satelite systems, are the most common alternative means ofcommunication
its mainly done through radio;but,mobilephones,televisions and satellites are also useful.
cb radio may be alternative????
mainly we can tell that the communication duiring disaster is very inevitable most probaly a radio-fm am could be the best of all also the use of satellite ensure good and quorate mode of communication in the times of a disaster
The general modes (mobiles, phones, etc.) depend on towers, wires which offer no resistance to a disaster. That means there will be no communication if a disaster kills these modes so each and every country ought to go for such systems which are not dependent on the electric supply, sunlight, etc
This is a very difficult question to answer because it depends upon the geographical area affected (this will determine the infrastructure already in place) and then the nature and magnitude of the disaster (e.g. earthquake, tornado, flood, blizzard, nuclear disaster, hurricane, volcano eruption, fire etc) and the effect this has on that infrastructure (e.g. loss of power, loss of telephone/Internet, loss of mobile reception, collapse of road network etc) and then ultimately on what resources are available by governments and local communities to resolve the communication challenges. Power is often cited as the main component associated with the mitigation (use of other communication systems) and recovery of the different communication systems. The list below is an attempt to list the different types of communications systems that could be used in a disaster: (1) existing wireline/fibre optic phones and cables are in place; (2) existing mobile/cell phone technologies; (3) amateur radio communication systems; (4) governmental, military and disaster relief communications systems; (5) satellite communications systems; (6) business infrared or microwave systems (if available); (7) standard television and/or radio systems (one way communications); (8) people travelling using vehicles on roads; (9) people travelling of bikes; (10) people walking between places.
Satellites are used to effectively communicate during disasters. When a disaster hits, often satellite communication is the only means of communicating. Satellites can also provide authorities with weather updates. http://www.idirect.net/Applications/Business-Continuity-and-Disaster-Preparedness.aspx
For wireless communication systems, the antenna is one of the most critical components. A good design of the antenna can relax system requirements and improve overall system performance. An antenna is the system component that is designed to radiate or receive electromagnetic waves. In other words, the antenna is the electromagnetic transducer which is used to convert, in the transmitting mode, guided waves within a transmission line to radiated free-space waves or to convert, in the receiving mode, free-space waves to guided waves.
Battery-powered, of course.

Some alternative communication systems during a disaster include two-way radios, satellite phones, and hand signals. These allow rescuers to quickly coordinate their efforts and find victims.
Communication and record keeping.
The general modes (mobiles, phones, etc.) depend on towers, wires which offer no resistance to a disaster. That means there will be no communication if a disaster kills these modes so each and every country ought to go for such systems which are not dependent on the electric supply, sunlight, etc
Some persons with apraxia may decide to use alternative communication systems, such as a computer that transcribes and "speaks" what a person is directing it to say.
One may find information about disaster recovery systems from "Disaster Assistance". This is a government run website which helps inform people about different disaster recovery systems.

Friends there is one and only one website for CBSE Projects i.e www.icbse.com.You project i.e communication facilities in disaster managementis available at http://www.icbse.com/2009/communication-facilities-for-disaster-management-project/Communication is a major bottleneck in case of any major disaster particularly when the traditional network system already in force brake down. In order to strengthen communications, it has been decided that police network (POLNET) will also be used for disaster management. For this purpose POLNET communication facility will be extended to District Magistrates, Sub Divisional Magistrates as well as the Control Rooms.what is the roll of communication medias in disaster management?
Formal communication is important because it reaches all areas of business in newsletters, emails, and manuals. It follows rules, procedures, or established systems and is a smooth communication system. It provides a permanent record, increases efficiency, and is reliable.
what is the importance of accommodating expansion in plumbing systems ?
Wireless communication systems include pagers, cellular phones, personal communications systems
