Replanning options for 2 GHz band - consultation 23/2020

After considering issues and suggestions raised in submissions, we have decided to replan the 2 GHz band for mobile-satellite services with:

• 2 x 25 MHz (1980–2005 MHz paired with 2170–2195 MHz) for Australia-wide mobile-satellite services, with support for deployment of a complementary ground component (including direct air-to-ground communications services) where a licensee wishes to supplement its mobile-satellite service.
• 2 x 5 MHz (2005–2010 MHz and 2195–2200 MHz) for shared narrowband mobile-satellite services including telemetry, short messaging, and low-data-rate services such as satellite IoT applications.

Our considerations, planning decisions and indicative implementation timeline are outlined in the Replanning the 2 GHz band (1980–2010 and 2170–2200 MHz): Outcomes paper (see the ‘Key documents’ box).

To support introduction of mobile-satellite services, existing TOB services will be required to stop operation. Our preliminary view is that a timeframe of 5 years is appropriate for this in capital cities, and 3 years in regional areas where TOB usage is minimal.

We have started work on transition arrangements for TOB services and may consult on proposed arrangements in mid-2021.

For 1980–2005 MHz paired with 2170–2195 MHz, because demand is likely to exceed supply (expressed in responses to the options paper), our preliminary view is that a price-based allocation mechanism via auction is the most appropriate mechanism to resolve competing demand.

Further details on the licence allocation process for mobile satellite services and implementation timeframes will be determined through our annual five-year spectrum outlook process.

The issue

In 2012, the ACMA gave interim access to the 2 GHz band (1980–2010 MHz and 2170–2200 MHz) for television outside broadcast (TOB) services. This was pending a future review of the band. 

We have seen increased interest in the 2 GHz band for new applications, including:

• mobile satellite
• wireless broadband
• direct air-to-ground communications.

The ACMA believes a case exists for reviewing and possibly changing the arrangements in the band.

This paper is the preliminary replanning stage of the 2 GHz band. It follows the 2019 consultation, Planning of the 2 GHz band.

The options paper sets out desirable planning outcomes for the 2 GHz band and proposes three options. We would like your feedback on these and other issues in the paper.
