But, even though a good emergency communication system must be easy to use, its technology should be very advanced and complex. It should be advanced because that is needed in order to make sure many different things can work together, to create and send emergency communications in many possible ways. The important thing, though, is that an advanced system should still be easy for someone to use for both emergency and normal communications. The ability to use a system for normal communications is also important so the operator (who paid for the system) can get the most value. It is also important so that people can be familiar enough with the system that they can use it during a stressful emergency situation.
