The Australian Communications and Media Authority (ACMA) has finalized and implemented new regulatory arrangements for the 1.9 GHz band (1900–1920 MHz), following an extensive public consultation and technical analysis process. The new framework establishes clear licensing, coordination, and operational requirements for Railway Mobile Radio (RMR) and Short-Range Wireless Broadband (SR WBB) services, aiming to optimize spectrum use and ensure efficient coexistence among various services.

Key measures include the introduction of RALI MS51, which sets out licensing and coordination criteria for RMR services in 1900–1910 MHz, and amendments to RALI FX19 to cover SR WBB services in 1900–1920 MHz, with indoor-only operation and apparatus licensing. The Radiocommunications (Cellular Mobile Telecommunications Devices) Class Licence has also been updated to include new power and transmit control requirements for RMR mobile stations.

The regulatory package introduces updated transmitter licence taxes, including special provisions for underground RMR stations and population-based calculations. Coordination zones and mandatory collaboration between rail operators and 2 GHz band licensees are established, with distances and requirements adjusted according to receiver selectivity and operational status.

These changes are designed to protect critical rail communications, facilitate technological innovation, and provide a clear compliance pathway for all affected stakeholders, including rail operators, wireless device manufacturers, and telecommunications service providers.

This is a High Impact regulatory change.

Key reasons for high impact:

• Mandatory new licensing and coordination requirements for RMR and SR WBB services in the 1.9 GHz band
• Introduction of new technical and operational conditions, including power limits, coordination distances, and indoor-only restrictions
• Updated transmitter licence taxes and compliance obligations for a broad range of stakeholders
• Direct effect on the approval, deployment, and operation of railway communications, wireless broadband, DECT, BWA, and fixed link devices

Who is affected?

Rail operators, wireless device manufacturers, telecommunications service providers, DECT equipment suppliers, and fixed/BWA licensees.

Conclusion:

All stakeholders operating or planning to operate in the 1.9 GHz band must review and adapt to the new requirements to ensure compliance and continued market access.
