Exploring future use of the 1.9 GHz band - consultation 40/2021

Given the increasing interest in the 1880–1920 MHz band, a review of the band is required to determine whether there is a case for potentially changing arrangements in the band. The consultation paper examines possible planning scenarios for the band, including potential coexistence arrangements.

We welcome comments from interested stakeholders on any of the issues raised in the consultation paper. We specifically invite comments on:

1. What is the relevance of the Personal Handy-phone System (PHS) and should this use be retained?
2. What is the interest in the use of new technologies to provide a service?
   
   1. How much spectrum is required to provide the service?
   2. What interservice considerations need to be undertaken for the service to be deployed?
   3. What are the deployment scenarios for the service?
3. Are services still using DECT or are they transitioning to DECT-2020 NR?
4. Are there any applicable coexistence scenarios not identified? Are there any scenarios that are unlikely to be practically achievable (and hence the associated planning scenario should be discounted), or are there any that are readily achieved?
5. What are possible planning scenarios and industry views on the overall future use of the 1.9 GHz band and its services:
   
   1. How much spectrum is required (distinguishing between the minimum viable and desirable) to provide the service?
   2. Is there a clear geographical delineation – for example, metropolitan or regional – for the service?
   3. Is there or will there be equipment readily available for the service?

   Submissions will help us assess whether there is a case for potentially changing arrangements in the 1.9 GHz band, including whether to progress the band to the ‘preliminary replanning’ stage of the ACMA replanning process. If progressed, we will consult on detailed planning options for the band before any regulatory decisions are made.
