TETRA is an acronym for TErrestrial Trunked RAdio.

Tetra is an open voice standard developed by the European Telecom Standards Institute (ETSI) and is in use primarally overseas and in Europe. It uses a 4-slot TDMA channel. Tetra systems use the TETRA Control Channel.

There is not a scanner available today that can monitor Tetra Digital Voice.
