Physical Layer Convergence Procedure (PLCP)

The upper PHY sublayer that prepares MAC frames for transmission by adding a preamble and header.

Definition

PLCP converts MPDUs into PPDUs by adding a preamble for synchronization and a header describing rate and length. In current revisions, PLCP terminology is replaced by PHY service, but the concept remains. The PMD sublayer then modulates the bits.

Exam tip

PLCP adds preamble and header; PMD modulates.
