Common Public Radio Interface overview  |    A 3 day training course

CPRI training course description

This course is designed to give the delegate a technical overview of the CPRI protocols and link setup. We will explain the industry cooperation to define the key internal interface between the radio equipment control (REC) and the radio equipment (RE). Also explained will be the SAP that the CPRI link supports for IQ Interface, frame synchronisation, link control and management and the master and slave ports. We will investigate the CPRI block diagram and together with the data formats and sample mapping solutions. The CPRI frame hierarchy and hyperframe construction will be detailed during this three day overview course.

What will you learn
  • Explain the CPRI Block diagram.
  • Understand hyperframing capabilities.
  • Explain the CPRI frame format.
  • Understand how the synchronisation is compliant with 3GPP & WiMAX requirements.
  • Understand the two electrical characteristics of CPRI standard.
  • Understand the CPRI standards structure.
  • Understand the CPRI system & Interface definitions.
  • List the four standard bit rates of the CPRI specification.
  • Understand the CPRI Protocol stacks.
