66 NEXEDGE - TETRA Comparison

67 66 NEXEDGE - TETRA Comparison  TETRA (Terrestrial Trunked Radio) is an open standard for digital mobile radio communication defined by ETSI (European Telecommunications Standards Institute).  Originally conceived and developed for use by European Union government and public safety agencies. Later adopted as the worldwide “de facto” standard, except North America, for digital radio communications systems.  Provides a high-end solution for small private systems up to large public networks, while preserving characteristics and advantages of private land mobile radio systems, such as fast call set-up, group calls, and direct mode communication (talkaround). What is TETRA?

68 67 NEXEDGE - TETRA Comparison  TDMA (Time Division Multiple Access)  Each RF carrier (radio channel) is divided into 4 x timeslots within a 25 KHz channel  The transmission rate is 7.2 Kbps per timeslot.  Modulation: π/4 DQPSK  Vocoder: Adaptive Code Excited Linear Prediction (ACELP) TETRA General Concepts

69 68 NEXEDGE - TETRA Comparison  Is a trademark name of KENWOOD Corporation and a generic term used when refering to KENWOOD‘s Digital Communication System.  NEXEDGE technology is based on NXDN Common Air Interface (CAI).  NXDN is a trademark name of KENWOOD Corporation and ICOM Incorporated.
