    INTRODUCTION
    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.

    For emergency communication, mobile satellite based units which can be transported to the site of the disaster are being procured. A group was constituted to draw a comprehensive communication plan for disaster management and the report has since been received. This provides for a dedicated communication system for disaster management with built in redundancies.

    Besides the satellite, communication and education can play a proactive role in mitigation through awareness about the types of disaster and as to how prevention measures can be taken up.

    There is also a Satellite based communication system called the Cyclone Warning Dissemination Systems (CWDS) for transmission of warnings. There are 250 such cyclone-warning sets installed in the cylone prone areas of east and west coast. The general public, the coastal residents and fishermen, are also warned through the Government mechinery and broadcast of warnings through AIR and Television.
     

    use radio as a communication facility

    Radio nowadays is important facility for disaster management. Two ways communication radio could be used to extend information from/to disaster location. When natural disaster happened, normal communication facilities like mobile phone, PSTN, BTS towers, phone lines used to be destructed/failed as well, so at this time, radio / amateur radios act as emergency communication services those could relay informations to/from disaster location. Of course amateur radio itself that serves emergency communication should have good strength against power of natural disaster, and could be operated uses emergency power supply.

    Communication range of emergency amateur radio station is relative dues to frequency that is used. Could be short range if VHF used (up to 50km), or long range if HF used (up to 20,000km).
     

    HAM RADIO

    Amateur radio is a community of people that use radio transmitters and receivers to communicate with other Amateur radio operators. 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.
    Amateur (HAM) Radio is truly a hobby but often one that makes a difference especially in emergency or disaster situations. It is an activity of Self Learning, Inter-Communication & Technical Investigation carried on between Amateur Radio Operators. Amateurs talk to local friends over the radio waves using a hand-held transceiver, communicating digitally with packet radio to exchange personal messages or vital information in an emergency, talking to other hams anywhere in the world, or engaging in contests with other Radio Amateurs over the airwaves there is something for everyone.
    There are over Lakh people all over the world who pursue this activity in their free time

    Key to disaster management - Effective Communication
    The world is not a very safe place to live in these days as disaster and terrorism can strike at any moment. Communication is the only relief as times of disaster and hence the need for a efficient disaster management system becomes imperative in public places and even in business establishments and important commercial joints where people move around in large numbers. Disaster might strike in the form of natural calamities, terrorist's attacks and accidents. Thus an efficient disaster management system which will work in adverse conditions is needed. In times of natural calamity like floods, storms or fire the usual mode of communication like phone, mobile etc might not work or might be lost in the calamity.

    Consider this, underground communication lines get disabled due to flooding, cell towers are blown over or simply choke due to high utilization, backup generators run out of fuel — or are filled up with water.

    Whatever be the situation, one can not rely transporting fuel to keep the power up for vital facilities since the power lines could be snapped (often seen in photographs) with uprooted trees and power lines and towers twisted and broken completely, or simply there is no road to the generators - either due to floods, or due to various obstacles like trees, or damaged roads or bridges.

    There are others with Radios - Why HAM Radio?
    Radios of police may not be necessarily on same frequency as that of firefighters. The military has it's own set of frequencies and even other departments that use radio for communication can communicate, however the communication is limited within there own group! The truth is they cannot communicate with each other - and that is The biggest challenge. How to convey message between diverse group of disaster or relief agencies when they all have sets, but cannot talk to each other.

    The response phase after any disaster includes the mobilization of the necessary emergency services and first responders in the disaster area. This is likely to include a first wave of core emergency services, such as firefighters, police and ambulance crews. This is where HAM (Amateur) Radio comes in picture. Using HF radio sets, messages can be conveyed or relayed to long distance and accurate picture of situation on the ground, requirements and key information could be sent to disaster response team.

    Advantage Amateur (HAM) Radio Operators
    The society at large must be well protected and the protection given by the disaster management forces must be instant and immediate. Thus the disaster management crew must be well trained and equipped with the best appliances which might help them to communicate the condition they are in and the status of the calamity in the region they work for. With HAMS, Amateur Radio operators, you have a ready workforce that is efficient with regards to communicating with each other 'efficiently' and 'effectively'. They are known for innovation and apt at adapting to situations. Unlike commercial systems, Amateur radio is not as dependent on terrestrial facilities that can fail. It is dispersed throughout a community without "choke points" such as cellular telephone sites that can be overloaded.

    Amateur radio operators are experienced in improvising antennas and power sources and most equipment today can be powered by an automobile battery. Annual "Field Days" are held in many countries to practice these emergency improvisational skills. Amateur radio operators can use hundreds of frequencies and can quickly establish networks tying disparate agencies together to enhance interoperability.

    Some recent examples where HAM Radio operators played a significant role in communication during disasters

    * 2001 attacks on the World Trade Center in Manhattan
    * 2003 North America blackout
    * Hurricane Katrina in September 2005


    In India

    * Orissa Cyclone
    * Latur Earthquake
    * Tsunami
    * Aila

    Despite the fact that many states in India get affected by natural and other calamities, proper coordination between different agencies is still not very effective. Amateur Radio Operators volunteer to offer help as and when needed, however there is no national database on active operators who can be called upon during any disaster, and also if they have right setup (which means - ready to go on air gear) at short notice. UN and other agencies do allocate funds to various departments for establishing suitable amateur radio stations, but apathy and lack of vision has so far done nothing substantial to setup a national backbone or disaster management setup other than creation of various agencies for disaster management.

    Amateur Radio has also been included in school textbooks, but nothing beats a practical demonstration and in that regard, not many would ever see a rig in operation. They could write about it in exams without even looking at how an amateur radio really looks like!

    A ham radio operator can carry on experiments with various communication equipment and systems going deeper into the science of electronics (Learning by Doing) and at the same time provide great service to the people in general worldwide by way of organizing on-the-air emergency medical traffic, establishing emergency communication network during natural calamities like flood, cyclone, storm, earthquake or any other disaster. Amateur Radio stations act as the 'SECOND LINE' of communication when existing public or government communication links fail to act. life-saving facet of amateur radio was demonstrated in India with valuable public service activities during a Post & Telegraph Strike in 1960, when radio amateurs passed important messages for the public. In September 1979, during the flash floods at Morvi due to the Machhu dam burst in Gujarat, more than a dozen amateur radio stations of western India activated emergency radio stations to pro-relief agencies, government officials and victims of the disaster in the cities of Rajkot, Baroda, Ahmedabad and Mumbai. Similar services were rendered by hams during the cyclonic storms in Saurashtra and a number of times in Andhra Pradesh-a state prone to cyclonic storms following weather distrurbances over the Bay of Bengal. You might recollect the earthquakes in Uttar-Kashi and more recently at Latur in Maharashtra and adjoining areas where ham radio operators provided the essential communication network for coordinating and organising relief operations, arranging medicines, food and clothing for the affected people. This specialized technical sports or hobby is very much a national asset like any other non-governmental public service organisation (e.g. the Red Cross). Ham Radio has reestablished its importance during the recent Orissa disaster (the devastating cyclone), when all the communication facilities broke down. A ham radio station set up at the Orissa Chief Minister's residence maintained contact with the nation's capital for nearly a month. Amateur radio stations also come into action during the major sports event like the ASIAD, the HIMALAYAN CAR RALLY to assist the sports officials as well as the rally operators. The Himalayan Expedition teams are getting assistance from the ham radio operators.

    Telecommunication is critical at all phases of disaster management. Aspects of radiocommunication services associated with disasters include, inter alia, disaster prediction, detection, alerting and relief. In certain cases, when the "wired" telecommunication infrastructure is significantly or completely destroyed by a disaster, only radiocommunication services can be employed for disaster relief operation. Two major tasks of the ITU-R - ensuring the effective use of the radio-frequency spectrum and studies concerning development of radiocommunication systems - concern all radicommunication services. Moreover, the Radiocommunication Study Groups carry out studies related to the continuing development of radiocommunication systems used in disaster mitigation/relief operations and these can be found within work programmes of the Radiocommunication Study Groups. Disaster phases Major radiocommunication services involved Major tasks of radiocommunication services Studies carried out by Radiocommunication Prediction & Detection Meteorological services (meteorological aids and meteorological-satellite service) Earth exploration-satellite service Weather and climate prediction. Detection and tracking of earthquakes, tsunamis hurricanes, typhoons, forest fires, oil leaks etc. Providing warning information Study Group 7 Alerting Amateur services Receiving and distributing alert messages Study Group 5 Broadcasting services terrestrial and satellite (radio, television, etc.) Disseminating alert messages and advice to large sections of the public Study Group 6 Fixed services terrestrial and satellite Delivering alert messages and instructions to telecommunication centres for further dissemination to public Study Group 5 Study Group 4 Mobile services (land, satellite, maritime services, etc.) Distributing alert messages and advice to individuals Study Group 5 Study Group 4 Relief Amateur services Assisting in organizing relief operations in areas (especially when other services are still not operational) Study Group 5 Broadcasting services terrestrial and satellite (radio, television, etc.) Coordination of relief activities by disseminating information from relief planning teams to population Study Group 6 Earth exploration-satellite service Assessment of damage and providing information for planning relief activities Study Group 7 Fixed services terrestrial and satellite Exchange of information between different teams/groups for planning and coordination relief activities Study Group 5 Study Group 4 Mobile services (land, satellite, maritime services, etc.) Exchange of information between individuals and/or groups of people involved in relief activities Study Group 5 Study Group 4 ITU-R is also invited to pursue studies on the further identification of suitable frequency bands that could be used on a global/regional basis for public protection and disaster relief (PPDR), as well as on facilitating cross-border circulation of equipment intended for use in emergency and disaster relief situations - the second of these tasks being reinforced by the Tampere Convention on the provision of telecommunication resources for disaster mitigation and relief operations. Recognizing that the immediate availability of pre-identified and pre-coordinated frequencies, and/or spectrum are important for the successful use of radiocommunications in the very early stages of humanitarian assistance intervention for disaster relief will save many lives, WRC-07 adopted Resolution 647 (WRC-07). This Resolution requests the BR Director "to assist Member States with their emergency communication preparedness activities by establishing a database of currently available frequencies for use in emergency situations, which are not limited to those listed in Resolution 646 (WRC-03)". Impetus for the work also comes from several Resolutions of World Radiocommunication Conferences (Resolution 644 (Rev. WRC-07) , Resolution 673 (WRC-07) requesting ITU-R to study aspects of radiocommunications relevant to disaster mitigation and relief operations and studies on possible means to improve recognition of the essential role and global importance of Earth observation applications. The Radiocommunication Assembly 2007 (RA-07) approved Resolutions ITU-R 53 and ITU-R 55 instructing all ITU-R Study Groups to carry out studies on the use of radiocommunications in disaster prediction, detection, mitigation and relief.

    It's HAM Radio, That works when everything ELSE fail. During a Diasater, Power can Fail, Tower can fall, Satellite Uplink Station might get damaged, Conectivity lines fails, power problems, It may be just ok for a few hours to sustain on other modes of support like Diesel generators for power, Satellite Phones , Broadcast ..... but when Generators get overloaded, heated up, lack of transport and availabity of fuel ??? then what ........... Even When everthing ELSE fail, use HAM Radio, which is independent, no big towers required, a couple of meters of wire can be tuned to a antenna, no big power required, even a UPS battery or a BiCycle dynamo can be used to power it, Solar cell, it can sustain as it can be operated with low power for longer duration ...... as far as you have POWER to peddle the Cycle with Dynamo ....
