Notice No. SMSE-008-08 - Proposed Revisions to the Technical Requirements for Fixed Service in the Bands 1700-1710 MHz and 1780-1850 MHz
The purpose of this notice is to announce the release of the above-mentioned consultation, which seeks comments on proposals to revise the band plan for fixed line-of-sight radio systems operating in the bands 1700-1710 MHz and 1780-1850 MHz, including provisions enabling the use of the frequency band 1800-1830 MHz for systems for the operations, maintenance and management of the electricity supply, and to update the technical requirements applicable to systems throughout these bands.
In SP 1-20 GHz, released in 1995, the frequency range 1700-1850 MHz was designated for low-capacity (LC) and very low-capacity (VLC) point-to-point systems. One of the priorities of the policy provisions was to accommodate microwave stations that were subject to displacement as a result of the introduction of personal communication services (PCS) in Canada.
In October 1999, the Department issued Amendments to the Microwave Spectrum Utilization Policies in the 1-3 GHz Frequency Range. Due to pending changes to accommodate new mobile services in the band 1710-1850 MHz following WRC-2000, the policy discouraged any growth for fixed line-of-sight services in this band, particularly for large-scale multi-hop networks or for systems deployed in urban areas and their vicinities.
In February 2007, as part of DGTP-002-07, Consultation on a Framework to Auction Spectrum in the 2 GHz range including Advanced Wireless Services (AWS Consultation), changes were made to the Canadian Table of Frequency Allocations in the band 1710-1850 MHz. Some of these changes are listed below:
- The band was split into two new bands, namely 1710-1755 MHz and 1755-1850 MHz;
- Mobile service was designated as a primary service in the band 1710-1755 MHz; and
- A new Canadian footnote C37 was added to the band 1755-1850 MHz regarding a possible future designation for AWS in the sub-band 1755-1780 MHz, subject to a future public consultation.
The Department has recently received submissions from Canadian electric utility companies associated with the Utilities Telecom Council of Canada (UTCC), regarding the need for wireless spectrum to accommodate emerging and urgent telecommunication requirements to improve the efficiency of the electricity use and ensure the integrity of the electrical grid infrastructure through improved monitoring and control.
The Department proposes to respond to the UTCC's request by changing some of the technical requirements in SRSPP-301.7, applicable only to radio systems carrying information for the management and operation of the electricity supply, and only in the 1800-1830 MHz block. As well, the Department intends to review the technical specifications and the band plan for all fixed systems deployed in the bands 1700-1710 MHz and 1780-1850 MHz.
The 1800-1830 MHz block was chosen because it is part of the band 1780-1850 MHz, which is currently available for point-to-point fixed systems. Modifying (relaxing) some of the technical requirements in the 1800-1830 MHz block would enable deployment of a large number of fixed links in a "star" topology, which is in line with the power utilities requirements.
The 1800-1830 MHz block would not be dedicated only to radio systems for electricity infrastructure. Other fixed point-to-point radio systems would still have equal access to this block on a first-come, first-served basis under the current technical rules for this band.
Interested parties are invited to submit comments on the proposals outlined in the consultation no later than August 6, 2008, in electronic format (WordPerfect, Microsoft Word, Adobe PDF or ASCII TXT) to the following e-mail address: email@example.com, along with a note specifying the software, version number and operating system used. Written submissions should be addressed to the Director, Spectrum Engineering Branch, Industry Canada, Room 1943B, 300 Slater Street, Ottawa, Ontario, K1A 0C8. All submissions should cite the Canada Gazette, Part I, publication date, the title, and the notice reference number (SMSE-008-08).
