DMR System Design


1 Day / 2 Live Online Sessions (0900-1230) / Technical Level: Level 3

Course Code: PR1302

Course Summary

The topics covered in this course will enable those working in radio system design, specification and optimization to plan and configure DMR networks. The course contains detailed descriptions of the key aspects of the DMR radio link including higher-layer signalling, protocol interactions and media processing aspects as well as lower-layer functions such as modulation, radio performance and channel coding.

Who would benefit

Engineers working or involved in radio system design who require a detailed understanding of the planning, optimization and configuration aspects of Tier I, Tier II and Tier III DMR systems.

Prerequisites

Familiarity with the principles and techniques of designing mobile radio systems, or previous attendance on the Radio System Design course (RP1101).
