The amalgamation of a number of channels is allowed provided the equipment (or the system) meets the spectrum efficiency criteria set out in the certification section of this document. The Department introduces a redeployment plan that will increase spectrum efficiency in the bands 150 MHz and 450 MHz through the introduction of more spectrum efficient equipment. The redeployment plan will take place in two phases that will require a transition to more spectrum efficient equipment to free-up more mobile spectrum in areas of intensive mobile use where additional mobile users cannot be accommodated. In Phase 1, this will be accomplished through specific channel plans, certification and deployment.
