Default synchronisation and frame structure for 3.3-3.8 GHz mobile broadband use

Jonathan Brewer made this Official Information request to Ministry of Business, Innovation & Employment

This request has an unknown status. We're waiting for Jonathan Brewer to read a recent response and update the status.

From: Jonathan Brewer

Dear Ministry of Business, Innovation & Employment,

Radio Spectrum Management's 15 December 2021 presentation "Technical Working Group on 3.3-3.8 GHz" describes two options for harmonisation of synchronisation and frame structures across the 3.3-3.8 GHz frequency band.

Option A is described as limiting cell sizes to a radius of ~9 km, and Option B is described as allowing for cell radius up to ~14.5 km, and the potential for co-existence between 4G and 5G services.

Please release any and all emails, documents, research, and presentations to cabinet that discuss the topic and how choices could impact the availability of high speed broadband for rural and remote users.

Additionally please advise:

1.) Have rural stakeholders been engaged to discuss technical choices that could limit the use of the frequency band to either ~9 or ~14.5 km from a tower? If so, how has this engagement process been run, and what feedback has been received in response?
2.) Has the Commerce Commission been consulted on the potential for a reduction in competition in the rural services market should a technical choice restrict the availability of equipment or result in economically untenable situation for rural and remote providers?

Yours faithfully,

Jonathan Brewer

Kia ora Mr Brewer

Thank you for your OIA request of 9 May 2022.

We have not identified any information provided to Cabinet that mentions the two options outlined in the presentation to the Technical Working Group that you have referred to. However we have identified a Cabinet paper called "Allocation of 3.5 GHz spectrum to support the rollout of 5G and the advancement of rural connectivity" which we believe may be of interest to you based on your email.

The Ministry is enquiring whether you would like to change the scope of your request to be for this Cabinet paper instead?

Please note that if you agree to this change, it is likely that a transfer to the Minister of Digital Economy and Communications may be necessary as the proper decision-maker on this material.

Alternatively, we would be grateful for any further guidance on the information you are requesting.
