TETRA History

• Early 1990s – Proposal to ETSI– Initially for shared commercial

– Later to include Public Safety user needs

• Mobile Digital Trunked Radio System (MDTRS)

• TErrestrial Trunked RAdio (TETRA)

TDMA v FDMA?

TETRA

• 4 slots in 25kHz  =  6.25kHz efficiency4 times more efficient than GSM!

• Designed for those who work, and need to communicate, in Groups.

Core Technology

• 4 slot TDMA in 25kHz channels(6.25 equivalent)

• /4 DQPSK Modulation

• Gross data rate 36kbit/s, Net 28kbit/s

• Circuit and packet mode data

• Low bit rate ACELP codec (4.6kbit/s)

• Fast call setup <300ms typical

• Air Interface and End to End Encryption
