TETRA Advanced provides comprehensive coverage of the TETRA standard. It has been designed to provide a more in-depth knowledge of the TETRA air interface’s, especially the protocol stack architecture and radio aspects, operations, as well as issues relevant to the TEDS, TETRA security aspects (both DMO and TMO) network planning, coverage predictions and capacity dimensioning.
EXPECTED ACCOMPLISHMENTS
- Describe the architectural components on the TETRA network
- Describe different TETRA topologies
Estimate the traffic supported in each cell - Dimension a TETRA network from the coverage and capacity perspective
- Describe the role of each layer of the TETRA air interface protocol stack
- List teleservices, bearer services and supplementary services that can be enabled in TETRA
- Describe the CS and PS data capabilities of TETRA
- Justify and explain the operation of π/4 DQPSK as the TETRA modulation scheme
- Describe TETRA radio transmission and reception performance characteristics
- Describe the physical layer structure in terms of bursts, timeslots, frames and multiframe
- List the TETRA physical and logical channels and identify their mapping relationships
- Describe the functions of the MAC layer in relation to call procedures and error protection
- Describe key signaling scenarios
- Describe the capabilities, procedures and air interface structures for DMO and TMO operation
TARGET AUDIENCE
Managers, Engineers, and Technicians involved in the planning, deployment and maintenance of professional mobile networks
