The ACMA is seeking comment on updates to Radiocommunications Assignment and Licensing Instruction (RALI) FX16 and RALI FX17 to provide for telemetry systems requiring increased data rates that support enhanced functionality in site monitoring applications. Currently these RALIs provide advice on frequency coordination requirements for point-to-multipoint and narrowband single channel two frequency point-to-point services in the 400 MHz, 800 MHz and 900 MHz bands with channel bandwidths up to 25 kHz.
In this update, the ACMA is proposing:
- to include the VHF high band (148–174 MHz) in the scope of the two RALIs
- add support for 50 kHz channels in both FX16 and FX17 in the VHF high and 400 MHz bands.
The ACMA has been considering requests for 50 kHz channels in the VHF high and 400 MHz bands on a case-by-case basis. This update will remove the need for case-by-case out of policy requests for such systems.
As RALIs FX16 and FX17 also cover the 800 MHz and 900 MHz bands, they have been reviewed to reflect the current status of the 803–960 MHz review implementation.
This work was foreshadowed in the Spectrum planning framework—Frequency coordination requirements review work program released by the ACMA in September 2018.
