![]() Notice No. DGTP-002-03Industry Canada Radiocommunication Act Notice No. DGTP-002-03 — Restructuring the Spectrum in the Band 3400-3650 MHz to More Effectively Accommodate Fixed and Radiolocation Services Intent The purpose of this Notice is to announce a rearrangement of the spectrum in the band 3400-3650 MHz to better accommodate fixed wireless access (FWA) systems and radiolocation operations. The core spectrum for FWA systems is being rearranged to reduce the potential interference from high-power radiolocation systems operating in the lower part of the band. Existing priority spectrum for radiolocation services must be preserved for the Government of Canada to support increased operational activities [Footnote 1] necessary to ensure national security and public safety to Canadians within the domestic borders and beyond. Discussion In 1997, the Department allocated the band 3400-3500 MHz to the fixed service on a co-primary basis with the existing radiolocation service, with provisions to ensure that the radiolocation service had priority over the fixed service in certain locations of the country for the Government of Canada. Then, with the issuance of the 1998 spectrum and licensing policy, the band 3400-3550 MHz was designated for FWA systems and immediately opened for licensing in rural areas, on a first-come, first-served basis. An objective for opening the spectrum in rural Canada was to provide a wireless access alternative to the traditional wireline local loops for improving multi-party telephone lines, especially in high cost serving areas. The Department observes that FWA implementation has not been a significant factor in advancing this objective. However, with emerging, new FWA systems, there has been a renewed interest in wireless access facilities for high-speed Internet service. Concurrently, with the increased level of radiolocation activities to ensure national security and public safety, the Department has had to assess the impact of high-powered radiolocation operations in spectrum adjacent to or partially within the band used by FWA systems. Particular attention has been given to the spectrum requirement for radiolocation operations within Canada and along the Canada - U.S. border and the coastal waters. The Department undertook discussions with the Canadian Department of National Defence and the U.S. Administration, including U.S. Government users to better understand the radiolocation operations, the spectrum requirement and the potential for interference between FWA and radiolocation systems. As a result of these discussions, the Department has reached the conclusion that in order to accommodate both services, the FWA spectrum must be realigned so that (i) the existing priority spectrum for radiolocation is preserved and (ii) the spectrum for commercial FWA service receives minimal interference. It is expected that these changes will have minimal disruption on a relatively small number of FWA systems operating in rural areas. Spectrum Policy Modifications Effective immediately, the Department is making some changes to its 1998 spectrum policy (Spectrum Policy and Licensing Provisions for Fixed Wireless Access Systems in Rural Areas in the Frequency Range 3400-3700 MHz - referred to as SP 3400-3700 MHz) to provide for the spectrum requirements for radiolocation operations and for FWA systems in rural areas, that are licensed on a first-come, first-served basis. The summary of spectrum policy modifications is outlined below (the new band plan and designation status is shown in the table below): 1. Modifications to Frequency Allocation and Utilization:
