Emergency communication system
Emergencies can make communications difficult. Communicating during emergencies can be very different than communicating during normal times. When emergencies happen, many things about the situation can change suddenly. Because of that, an emergency communication system should be able to do many special things. Often, popular communication tools (for example, Email) are not fast enough or they can not be used in every place. Every emergency situation can be very different and difficult to predict, so a good emergency communication system must be able to work for every situation.
