Meteor burst communication
The ionized trail can last for several seconds.  During this time messages can be sent between two radio communication stations.  The messages will be transmitted very fast: about 200 times as fast as with ordinary shortwave radio communication.  A teletypewriter may type several lines of text during a meteor burst. The two stations that want to communicate will have to be ready all the time as they never know when the next burst of communication will come.  They may have to use several meteor bursts before the whole message is received.  The transmitters are often put on buoys in the sea.
