Spectrum Management
Industry Canada:
– Participates in international frequency allocation work;
– Establishes domestic frequency allocation and spectrum utilization policies;
– Introduces legislation, regulations, equipment standards, licensing policies and procedures;
– Issues Radio authorization;
– Ensures Compliance; and
– Performs other duties related to spectrum management.

WiMAX
• “Equipment is certified to conform with IEEE 802.16 and ETSI HiperMAN standards”, and
• “Will provide broadband access for
– Fixed, portable, nomadic and eventually mobile use.”
• System profiles address the spectrum allocations, channeling plans, and standards of different countries.

Radio Spectrum and WiMAX
• WiMAX has profiles for fixed systems:
– 5.8 GHz for licence-exempt equipment.– 2.5 and 3.5 GHz for licensed equipment, and
• In the near future, profiles for fixed and mobile systems:
– 2.3 and 2.5 GHz licensed equipment.
• Other possible bands of interest?
– 4.9 GHz, 700 MHz, and others...

FACT
“Industry Canada does not designate spectrum for specific technologies, such as WiMAX, but WiMAX can be used in any band, subject to compliance with the technical limits.”
source: “The Implications of WiMAX for Competition and Regulation”, a report by the Working Party on Telecommunication and Information Services Policies, OECD, March 2, 2006.

Canadian Rules on 5 GHz
The primary allocation varies by sub-bands, but the footnotes C39A and C39B allocate these frequencies to licence-exempt local area network use. In Canada, the spectrum policy for this band is SP-5150, while the equipment standard is RSS-210.

Canadian Rules on 2.3 GHz
• One paired blocks (15 + 15 MHz), although the licensees may divide them into sub-blocks.
• WCS operators have to consider the presence of satellite radio terrestrial repeaters and vice versa. Provisional coordination procedure has been published.

13
Canadian Rules on 3.5 GHz
• 7 × 25 MHz channels in 3475 – 3650 MHz :
– Three paired blocks and one single block.
• 3.5 GHz licensees have to expect occasional interference from U.S. radiolocation devices (radars) in areas close to the border and in Canadian coastal waters.

14
Status of 2.3 GHz and 3.5 GHz
• After two auctions in 2004 and 2005, 32 entities were awarded 840 spectrum licences offered in the 2.3 GHz and 3.5 GHz bands in Canada.
• Some licensees are deploying broadband wireless service using pre-WiMAX and WiMAX equipment.
• The Department is still to consult on 3650 – 3700 MHz.

Status of the 2.5 GHz MCS band
• In 2001, Industry Canada conducted competitive licensing for 2.5 GHz MCS spectrum in the country:
– Special provision was given to Manitoba, which already had many interactive ITV systems in use.
– Three licensees were awarded spectrum licences.
– All provinces and territories are covered.
![Page 17: 1 WiMAX and the Canadian Radio Spectrum April 28, 2006 Angela Choi Communications Engineer Pacific Region Industry Canada choi.angela@ic.gc.ca](https://reader036.vdocument.in/reader036/viewer/2022062519/5697bf9f1a28abf838c94e3f/html5/thumbnails/17.jpg)
17
Status of the 2.5 GHz MDS bands
• MDS is broadcasting so each operation must be authorized by the CRTC and certified to be technically acceptable) by Industry Canada:
– Authorizations are site specific and for estimated coverage areas; and
– 11 licensees hold authorizations to serve 86 communities.
• Some MDS operators are providing broadband internet service using excess capacity in their MDS spectrum.
![Page 18: 1 WiMAX and the Canadian Radio Spectrum April 28, 2006 Angela Choi Communications Engineer Pacific Region Industry Canada choi.angela@ic.gc.ca](https://reader036.vdocument.in/reader036/viewer/2022062519/5697bf9f1a28abf838c94e3f/html5/thumbnails/18.jpg)
18
New Canadian Policy on 2.5 GHz
• On March 30, 2006, Industry Canada published a new policy on the 2.5 GHz spectrum.
– Market force will determine if the spectrum will be used for fixed, mobile or broadcasting.
– Mobile spectrum is valuable and implementation of mobile service justifies reassessment of the licensing requirements.
![Page 19: 1 WiMAX and the Canadian Radio Spectrum April 28, 2006 Angela Choi Communications Engineer Pacific Region Industry Canada choi.angela@ic.gc.ca](https://reader036.vdocument.in/reader036/viewer/2022062519/5697bf9f1a28abf838c94e3f/html5/thumbnails/19.jpg)
19
New Canadian Policy on 2.5 GHz Cont.
• MDS operator may continue to offer broadcasting service, or apply to convert to MCS operation
• MCS operation must be fixed ONLY, no mobile service allowed.
• If an operator wants to offer mobile service, the operator must return 1/3 of spectrum to IC for auction.
• Unassigned MDS spectrum will be auctioned.

20
TBD Canadian Rules on 2.5 GHz
• Channelling plan may be harmonized with the U.S., where appropriate:
– Currently the channelling plan is for 6 MHz channels for 2500 – 2686 MHz.
– The new FCC plan (for BRS and EBS) is a mix of 1, 4, 5.5 and 6 MHz channels for 2495 – 2690 MHz.
• Licensing policy and procedures, including details of auctions.

21
Other Bands of Interest
• The WiMax Forum has commented on the Department’s consultation paper on 4.9 GHz.
• Upper 700 MHz (TV channels 60 – 69) is another band that is considered a potential candidate for WiMAX?
• The spectrum policies on these two bands are still to be decided in Canada.
![Page 22: 1 WiMAX and the Canadian Radio Spectrum April 28, 2006 Angela Choi Communications Engineer Pacific Region Industry Canada choi.angela@ic.gc.ca](https://reader036.vdocument.in/reader036/viewer/2022062519/5697bf9f1a28abf838c94e3f/html5/thumbnails/22.jpg)
22
4.9 GHz in Canada
• In 2005, Industry Canada gazetted a proposal on public safety fixed and mobile broadband in 4940 – 4990 MHz, and requested comments on:
• Eligibility criteria, including three categories of public safety organizations;
• Technical criteria, including a band plan of 1 and 5 MHz blocks;• Spectrum licence fees of $0.0048 per population, and service
standard of four weeks;• The need for interoperable frequencies; • The need to protect radio astronomy frequencies; and• Other issues.

700 MHz in Canada
• No sunset date yet for NTSC TV in Canada.
– There are 49 incumbent TV stations in channels 60 – 69, 31 of them are low power TV.
• A moratorium is in place for TV in channels 63 and 68, which are set aside for public safety mobile use.
• The Department is still to consult on channels 64 and 69.

25
700 MHz for Broadband Use?
• In the U.S., the sunset date for NTSC TV is now set to Feb 2009.
• Ch. 63, 64, 68 and 69 have been designated as public safety spectrum in the U.S. since 1997.
– Current FCC channelling plan is divided into narrow band (6.25 kHz) and wide band (50 kHz) segments.
– In March 2006, the FCC proposed to rechannelize these frequency bands to accommodate broadband communications.
