The Call for Input is now closed - thank you for the responses received. Non-confidential responses are published at the link shown in the column on the right.
The responses received have provided a valuable insight into the opportunities for enhanced sharing that this band could present.
This included information on the potential types of new applications that could possibly share with incumbents, as well as the associated technical challenges. In light of these responses we believe there is potential for further exploring enhanced sharing based on geographically defined authorisations while continuing to allow current and future deployments of incumbent Fixed and Fixed Satellite Services.
While several of the responses to our CFI focussed on the potential to deploy mobile services in this band, particularly under a 2-tier Licensed Shared Access framework that incorporates UK-wide Tier 2 licences we currently don’t consider this band a high priority candidate band for mobile services in the UK (as highlighted in our MDS update).
We therefore wish to continue our discussions with stakeholders with the starting point being that the demand for enhanced sharing in the 3.8 - 4.2 GHz band may be best met through geographically defined authorisations. These further discussions and the insight we gather from this engagement will inform and help shape our future work with the aim to facilitate enhanced sharing in 3.8 - 4.2 GHz.
The responses received in the CFI have helped start this discussion and we would be keen to hear from stakeholders who are interested in furthering the discussion in this area to further engage with us by contacting us on 3.8-4.2GHz.Sharing@ofcom.org.uk
This Call for Input (CFI) introduces the 3.8 GHz to 4.2 GHz band as a candidate band for enhanced spectrum sharing, for potential new innovative applications, and seeks feedback and input from stakeholders.
The document is being published alongside the Spectrum Sharing Framework, which sets out an approach to systematically review opportunities for spectrum sharing.
We apply the spectrum sharing framework throughout this document to consider the opportunities that this band could offer to enable enhanced spectrum sharing.
Our preliminary analysis indicates that the band is suitable for more intensive sharing, while taking into account incumbent services.
To assist stakeholders in their understanding of how the band is currently used we have also made available, in conjunction with this CFI, the incumbent users characteristics of use in an online interactive tool.
