CPC-4-1-01 – Application Procedures for White Space Database Administrators (WSDBAs)

Client Procedures Circular CPC-4-1-01, issue 2, Application Procedures for White Space Database Administrators (WSDBAs), outlines procedures to be followed by applicants who wish to be considered by Innovation, Science and Economic Development Canada (ISED) for designation as a WSDBA to operate a white space database (WSDB). Such WSDBs shall determine the spectrum available for use by licence-exempt white space devices (WSDs) while ensuring the appropriate protection of licensed systems operating within the same frequency range, that is the following white space frequency bands:

• 54-72 MHz
• 76-88 MHz
• 174-216 MHz
• 470-608 MHz
• 657-663 MHz

This document also defines the administrative and operational requirements that these WSDBAs shall meet in order to maintain their designation status.

The Minister of Innovation, Science and Industry (Minister), through the Department of Industry Act, the Radiocommunication Act and the Radiocommunication Regulations, with due regard to the objectives of the Telecommunications Act, is responsible for spectrum management in Canada. As such, the Minister oversees the development of national policies and goals for spectrum resource use and ensures effective management of the radio frequency spectrum.

In accordance with subsection 3(4) of the Radiocommunication Act, any power, duty or function under the Act or the Radiocommunication Regulations may be exercised or performed by any person authorized by the Minister to do so and, if so exercised or performed, shall be deemed to have been exercised or performed by the Minister.

Designated WSDBAs responsible for operating WSDBs will ensure effective sharing of the radio spectrum with licensed users when providing available frequencies to licence-exempt WSDs.

The Minister will designate such WSDBAs for operation in Canada in accordance with the requirements outlined in this document. As part of these requirements, designated WSDBAs will enter into contractual agreements with ISED for the purpose of maintaining their designation status. Such databases, managed by the WSDBAs, will identify available frequencies for use by certified WSDs based on their respective geographic areas.

In October 2012, ISED released SMSE-012-12, Framework for the Use of Certain Non‑broadcasting Applications in the Television Broadcasting Bands Below 698 MHz, allowing the operation of licence-exempt white space devices (WSDs) in the white space frequency bands. In this framework, ISED outlined general policies for the protection of licensed systems in the band through the use of geolocation and the establishment of database-driven systems operated by WSDBAs. Such database-driven systems will inform a registered WSD operating in the band which white space frequencies are available for use at the device's location. The systems would also be used to register the locations of fixed WSDs as well as the protected locations and frequencies of licensed incumbent services. In March 2019, ISED made updates to this framework in SMSE-003-19, Decision on the Technical and Policy Framework for White Space Devices. In January 2024, ISED made further updates to this framework in SPB-001-24, Decision on New Access Licensing Framework, Changes to Subordinate Licensing and White Space to Support Rural and Remote Deployment.

Database Specification DBS-01, White Space Database Specifications, sets out the technical requirements for the designation of a white space database administrator (WSDBA) and for the operation of a white space database (WSDB) capable of identifying available frequencies and associated maximum power levels for use by white space devices (WSDs) operating in the white space frequency bands.

Under the framework of DBS-01, any eligible applicant may seek designation by ISED to become a WSDBA, provided that they meet related technical and operational requirements. The process for this is described further in section 9 of this document.

Any prospective WSDBA is eligible to apply for designation by ISED. In order to be designated, applicants shall follow the procedures set out in this document and demonstrate that they meet all requirements.

In order to be eligible for designation, a prospective WSDBA shall establish and agree to maintain a business office and a delegated representative within Canada. Additionally, the WSDB shall be available for assessment by ISED during the system evaluation and testing phase. ISED will assess whether the WSDB is operating effectively and is compliant with all applicable technical requirements.

During the development process of the WSDB, access to ISED's licensing information is required. Access to the ISED licensing information is available on the Spectrum Management System Data web page, and refer to the 'White Space Data Extract' section for the information required by WSDBs.

There are three key phases to the WSDBA designation process:

1. the application phase
2. the evaluation and testing phase
3. the designation for operation in Canada phase

The applicant will need ISED's approval for the completion of each phase before moving onto the next phase of the WSDBA designation process. The following sections provide a description of the process.

9.1 WSDBA application phase

Applications received for designation as a WSDBA will be assessed on a first-come, first-served basis. Applications should be directed to the ISED point of contact identified in section 16 of this document.

If the application for designation includes information that is confidential or proprietary in nature, a WSDBA applicant shall indicate this to ISED.

9.1.1 Application receipt

In order for the application to be received by ISED and considered for designation status, applicants shall submit the required applicant information and system information listed in annex A and annex B, respectively.

When completing the application, the prospective WSDBA shall demonstrate to ISED that they possess sufficient technical expertise to establish and administer a WSDB in accordance with the requirements outlined in the DBS-01 standard.

Applicants are encouraged to consult with ISED (contact information provided in section 16) prior to submitting an application, to ensure that all required information has been sufficiently addressed.

9.1.2 Application review

ISED will only evaluate complete applications. Should insufficient information be submitted, or other problems arise due to missing or inconsistent information, the applicant will be contacted to provide clarifications or supplementary information.

ISED will review submitted information against the application requirements of this document and the requirements in the DBS-01 standard. Only applicants that meet the requirements of both documents (CPC-4-1-01 and DBS-01) will be eligible to become a designated WSDBA.

9.2 WSDB system evaluation and testing phase

Once the application phase has been completed and the submitted information is approved by ISED, the WSDBA designation process moves to the evaluation and testing phase.

During the evaluation and testing phase, the WSDBA shall first test its WSDB according to the test plan submitted under item B1 of annex B and approved by ISED. The WSDBA shall demonstrate that its WSDB meets the requirements of the DBS-01 standard by successfully completing all the test cases included in the test plan and sharing the test results with ISED for review.

Once the WSDBA's test results have been reviewed and approved by ISED, the WSDBA shall provide ISED with access to a test environment of its WSDB. ISED will then evaluate and test the WSDB to ensure that it complies with the requirements set out in the DBS-01 standard. Should insufficient information be provided or inconsistencies or errors arise when evaluating the WSDB against the DBS-01 standard, the applicant will be contacted to provide clarifications, provide supplementary information, or make modifications to the WSDB.

As part of the evaluation and testing phase, the WSDBA may also be required to grant ISED access to:

• certain elements of the WSDB
• certain functions performed by the WSDB and/or
• intermediate values obtained from internal calculations performed by the WSDB, including but not limited to geographical values describing the protected geographic areas around protected licensed systems

Additionally, ISED may require the WSDBA to provide detailed examples of calculations performed by the WSDB.

9.3 WSDBA designation for operation in Canada phase

Once the WSDB evaluation and testing phase has been completed and approved by ISED, the next phase is to designate the WSDBA for operation in Canada.

9.3.1 Execution of the designation agreement

Following successful evaluation and testing, ISED shall arrange the execution of a designation agreement in the sample format outlined in section C1 of annex C.

9.3.2 Designation letter

Upon successful completion of the application phase, system evaluation and testing phase, and execution of the designation agreement, ISED will issue a designation letter to the successful applicant in the sample format outlined in section C2 of annex C.

A list of all designated WSDBAs will be made available on ISED's Dynamic Spectrum Access web page.

ISED's designation of a WSDBA does not imply or otherwise suggest promotion or recommendation of the services offered by the WSDBA, nor does the designation imply or suggest that the WSDBA is an agent or otherwise a representative of ISED.

In order to maintain its designation status, a WSDBA shall, on an ongoing basis, meet all requirements of the terms and conditions of the executed WSDBA designation agreement with ISED. As such, a WSDBA shall ensure that it remains compliant with any new requirements established by ISED and shall demonstrate this to ISED if requested to do so.

12.1 Retaining designation status due to new technical and/or operational requirements

This section and its subsections provide additional information on the process for retaining designation status due to the introduction of new technical and/or operational requirements for WSDBs (e.g. upon the publication of new issues of the DBS-01 standard).

WSDBAs wishing to retain their designation status shall take the required steps, if any, to update their WSDB with the new technical and/or operational requirements and shall demonstrate compliance to ISED, if requested to do so, following a three-phase process: the application, the evaluation and testing, and the reconfirmation of designation.

12.1.1 Application for retaining designation status due to new technical and/or operational requirements

A WSDBA shall submit an application to ISED for retaining the designation under the new technical and/or operational requirements following a similar process to the one outlined in section 9.1 of this document.

The application for retaining designation under new requirements is subject to review and approval by ISED and shall:

• demonstrate the WSDBA's intention to maintain its designation status and to align with the new requirements
• provide a description of any changes made to the WSDB to align it with the new requirements along with an estimated timeline for the changes to be completed provide a description of any changes and/or updates to the latest WSDBA applicant information (annex A) previously submitted to ISED
• provide a description of any changes and/or updates to the latest WSDB information (annex B) previously submitted to ISED

Should insufficient information be provided, the applicant will be contacted to provide clarifications or supplementary information.

12.1.2 Evaluation and testing due to new technical and/or operational requirements

Once the application for retaining designation is approved by ISED, the WSDBA moves to the evaluation and testing phase, if needed, following a similar process to the one outlined in section 9.2 of this document. ISED will require the evaluation and testing of the WSDB in certain cases where it determines that the changes are significant enough for evaluation and testing to be warranted. ISED will ensure that the WSDB complies with the new technical and/or operational requirements and may perform additional testing of other elements of the WSDB to ensure that it maintains compliance with all other requirements set out in the DBS-01 standard.

12.1.3 Reconfirmation of WSDBA designation status due to new technical and/or operational requirements

Once the WSDB evaluation and testing phase has been completed and approved by ISED, the next phase is to reconfirm the designation of the WSDBA under the new requirements. It is anticipated that in most cases, the designation agreement already in place with the WSDBA would not be affected by new technical and/or operational requirements and shall thus continue to remain in effect.

Upon successful eligibility for continuation of the designation, ISED will issue a new designation letter to the WSDBA. This will be based on the sample WSDBA designation letter provided in section C2 of annex C.

In cases of harmful interference, as defined in the Radiocommunication Act, to protected radio systems suspected to be caused by a white space device, the radio user experiencing such interference should report the problem to its nearest ISED Spectrum Management office. A list of ISED's offices is provided in the Radiocommunication Information Circular RIC-66, Addresses and Telephone Numbers of District Offices. The procedure for investigating harmful interference to protected radio systems is set out in section 5 of ISED's Spectrum and Telecommunications Service Standards.

Where ISED determines that interference is being caused by a particular white space device, the Minister may issue an order to the operator of the device to cease or modify operation of the device under the Radiocommunication Regulations or pursuant to paragraph 5(1)(l) of the Radiocommunication Act where there is harmful interference.

In any case where there is interference being caused by a particular white space device, ISED may, upon written request, require a WSDBA:

• to cease to provide available frequencies to the interference-causing white space device or within a specified geographic area
• to take appropriate corrective actions to resolve interference concerns, linked to the WSDB operating problems or deficiencies and/or the WSDB's failure to meet technical and/or operational requirements as set out in the DBS-01 standard

Failure to comply with ISED's written requests related to interference may result in the revocation of a WSDBA's designation status.

ISED's revocation procedures of the WSDBA designation will follow the terms set out in the agreement with the WSDBA. ISED may revoke the designation of a WSDBA due to non-compliance with any ISED requirements, including failure to comply with ISED's written requests related to interference as specified in section 13 above.

Designation will also be revoked upon joint consent by ISED and the WSDBA to terminate the agreement.

A WSDBA whose designation status has been revoked by ISED will be removed from ISED's list of designated WSDBAs.

A WSDBA whose designation status has been revoked and who wishes to be redesignated may submit a new application for designation.

ISED may audit a WSDBA's WSDB operations at any time to ensure compliance with the agreement's terms and conditions, including technical and operational requirements.

Designated WSDBAs shall provide ISED with any requested information or documentation as required for completion of such an audit within 30 calendar days of the date of the initial request.

Where it is determined by ISED that a WSDBA is not in compliance, immediate corrective actions shall be taken by the WSDBA to ISED's satisfaction in order to maintain the designation status. Failure to take such corrective actions, within the time period specified by ISED, may result in ISED's suspension or revocation of the designation status.
