The article discusses the conventional and trunked protocol testing methods being used to evaluate Project 25 (P25) digital radio communications standards. Information on the common air interface (CAI) specification used in the P25 standard is given. The need to distinguish key parameters in analyzing modulation accuracy and fidelity is emphasized. Reasons why trunked systems have the capability of handling high levels of users unlike conventional systems are described.
