  1. Update on Industry Canada’s White Space Database Specification (DBS-01) Joint Industry Canada/RABC Stakeholder Discussion - Ottawa, ON May 14th 2013

  2. DBS-01 White Space Database Specification Intent • Sets the minimum technical requirements for the designation of a database capable of indicating available channels for use by white space devices (WSDs)

  3. DBS-01 White Space Database Specification White Space Database (WSDB) • Provides lists of available channels to WSDs • Ensures protection of all licensed services and systems operating in the WS frequency bands • Uses geo-location to manage the operation of WSDs

  4. DBS-01 White Space Database Specification White Space Frequency Bands Note 1: Exclusion of Ch. 3-4 due to the use by consumer electronic devices in North America. Note 2: Exclusion of Ch. 37 due to protection of radio astronomy and wireless medical telemetry.

  5. DBS-01 White Space Database Specification Licensed Services and Systems to be Protected • Over-the-Air (OTA) TV Broadcasting; • Remote Rural Broadband Systems (RRBS) base stations; • Licensed Low Power Apparatus (LPA); • Radio astronomy, and • Medical telemetry

  6. DBS-01 White Space Database Specification Over-the-Air TV Broadcasting • WSDBs shall protect on-air stations only of the following: • Regular Power (DTV, Analog TV) • TV Translators, TV Boosters • Low Power/Very Low Power (DTV, Analog TV) • TV translators, TV Boosters • Receive-only stations making use of TV broadcast signals such as cable TV head-ends and low-power TV receive sites

  7. DBS-01 White Space Database Specification Current Status of OTA TV in Canada • Regular Power TV Stations: 341 • Digital: 188 (mostly in urban markets) • Analog: 153 (mostly in suburban markets) • LP TV Stations: 640 (mostly in suburban markets) • Digital: 24 • Analog: 616

  8. DBS-01 White Space Database Specification Broadcast TV Protected Contours Note: Refer to BPR-10 for DTV and BPR-4 for Analogue TV

  9. DBS-01 White Space Database Specification TV Protection Contour Example

  10. DBS-01 White Space Database Specification Interference Protection Criteria for TV Receiver Separation Distances • Protection of TV broadcasting from harmful interference by WSDs requires a physical separation. • The minimum separation distance is calculated using TV Broadcast Protected Contour values, TV Protection Ratios, the ERP WSD, EHAAT of the WSD, and the F-Curves. • Methodology on the Derivation of the Required Separation Distance to the TV Broadcast Protected Contours is shown in Appendix B.

  11. DBS-01 White Space Database Specification Sample of the Minimum Separation Distances from Fixed WSD to Broadcast TV Contours

  12. DBS-01 White Space Database Specification Sample of the Minimum Separation Distances from Mode II P/P to Broadcast TV Contours * WSDs with power levels of 40 mW (16 dBm) or less may operate within the protected contours of adjacent channel RRBS stations.

  13. Fixed WSDs Protect RRBS for co-channel,1st adjacent and 2nd adjacent channels based upon the associated RRBS protection criteria. Personal/portable mode II WSDs Protect RRBS stations for co-channel and 1st adjacent channels. WSDs with power levels of 40 mW (16 dBm) or less may operate within the protected contours of adjacent channel RRBS stations.

  14. DBS-01 White Space Database Specification Remote Rural Broadband Systems (RRBS) Protection Criteria

  15. DBS-01 White Space Database Specification Minimum Separation Distance of Fixed WSD to RRBS Station

  16. DBS-01 White Space Database Specification Minimum Separation Distance of P/P Mode II WSD to RRBS Station

  17. White Space Implementation Plan Low-Power Apparatus (LPA) Scheduling Limits/Rules • All licensed LPAs will only have protection from WSDs • Licensed LPAs with fixed locations will be protected for pre-determined periods in the WSDB. • Licensed LPAs not having a fixed location will need to register more precise scheduling information: • Exact location and time(s) of operation with a WSDB

  18. Registration facility required to collect location and time-of-use scheduling information for LPA. Location may be a point, radius or polygon. Multiple registrations that specify more than one point in the facility may be entered for very large sites. Ensure that updated licensed LPA scheduling information be exchanged amongst all of the WSDBs. Verify that the LPA is licenced. DBS-01 White Space Database Specification LPA Registration

  19. DBS-01 White Space Database Specification Separation Distance from WSDs to LPA

  20. Channel 37: Radio Astronomy Proposing a 2.4 km separation distance away from the centre based on the coordinates Dominion Radio Astrophysical Observatory (Penticton, B.C.) Algonquin Provincial Park (ON) Medical Telemetry DBS-01 White Space Database Specification Other Services to Protect

  21. Verify that the WSD is Industry Canada certified. Provide lists of available channels to certified WSDs. Use encryption to prevent corruption/modification of data between WSDB and WSDs. Ensure data is protected from unauthorized access, input, manipulation, or the deliberate extraction of operational and/or client data. DBS-01 White Space Database Specification Security

  22. Provide fixed and mode II WSDs with channel availability information and included schedule changes for the upcoming 48 hours, upon initial and re-verification of WSD contact. Provide available channel information to mode II personal/portable WSDs for locations beyond their current position. Define a geographic area within which they could operate on the same available channels at all locations. DBS-01 White Space Database Specification Database Access Initialization and Re-verification Procedures

  23. Ensure the synchronization of data of the most current Industry Canada licensing information with other WSDBs every day. Ensure that the scheduling information of licensed LPA is synchronized with the other WSDBs every 15 minutes. DBS-01 White Space Database Specification Synchronization

  24. U.S. broadcasting stations, protected receive sites and LPA are to be protected to the same criteria as specified for Canadian stations above, with the exception that protected contours and/or operational areas will be assumed to stop at the Canada/U.S. border. DBS-01 White Space Database Specification Protection of U.S. Stations

  25. WSDB must retain WSD technical parameters for [X] days for audit purposes in the case of interference reports. This information shall be provided to Industry Canada on formal request of the Department. WSDBs shall delete WSD locations after such time that no interference is reported.
