Welcome to the Cave-Link Homepage
Cave-Link is a data communication and measurement system for cave research and mining.
It allows safe data transmission thru several hundreds of meters of solid rock.
Beside measurement data it is also possible to transmit short text messages. If one of the surface stations is equipped with a GSM modem,
short messages (SMS) can be sent from and into the cave.
Due to the possibility of automatic forwarding thru several Cave-Link stations, even very great distances can be covered.
For communication VLF (Very Low Frequencies) frequencies were used. Coverage is up to 1300m and more from cave to cave.
Because all transmissions are secured by checksums and automatic query, no transmission errors are possible.
A bad link (great distance, atmospheric noise, interferences) just lengthens the communication time, but did not cause transmission errors.
