4.1 Recommendation 1
Up one level
- To efficiently cater for the introduction of APCO P25 phase 1, a channelling plan with a 12.5 kHz raster is implemented in conjunction with the existing 25kHz plan.
The majority of reviewers agree with the proposed recommendation. Further, one reviewer suggested that the majority of services would use 25 kHz channel spacing. 12.5 kHz APCO channels should be introduced depending on popularity.
The initial consultation process identified that there is an interest in APCO P25 (phase 1) systems. The implementation of a channelling plan with a 12.5 kHz raster allows APCO P25 to take place from the outset, providing a more efficient allocation of channels (figure 1). The current 25 kHz channel raster will remain in place, catering for the current analogue service, TETRA and other future 25 kHz applications as required. The current block allocation matrix will also remain in place.
