Notice No. DGTP-003-2000 — Proposed Revisions to the Spectrum Utilization Policy for Services in the Band 2285–2483.5 MHz

The purpose of this Notice is to announce a consultation paper on proposals for revisions to the spectrum policy and to advance certain policy decisions for services in the band 2285–2483.5 MHz. These modifications and proposals are in response to a number of requirements including innovative wireless access and LAN services for Internet.

This Notice follows the August 1997 consultation paper entitled Proposals to Provide New Opportunities for the Use of the Radio Spectrum in the 1–20 GHz Frequency Range, (DGTP-006-97) which solicited comments on numerous proposals throughout the 1–20 GHz frequency range.

In response to the August 1997 consultation paper, the Department received a wide range of submissions relating to the 1–3 GHz frequency range which were taken into consideration. In addition, several issues pertaining to the use of this frequency range have emerged, including the Canada/US agreement on spectrum for Digital Audio Broadcasting and US Digital Audio Radio Service (DARS) by satellite in the band 2320–2345 MHz, the US designation of Wireless Communication Services (WCS) to the bands 2305–2320 MHz and 2345–2360 MHz as well as the increased usage of licence-exempt devices in the band 2400–2483.5 MHz. In particular, the proposals and provisions included in this paper, address issues which affect fixed and mobile services (particularly mobile aeronautical telemetry services) as well as licence-exempt devices.

Based on the results of this public consultation, Industry Canada will establish spectrum utilization policies to respond to Canadian needs. Submissions should be addressed to the Director General, Telecommunications Policy Branch, Industry Canada, 300 Slater Street, Ottawa, Ontario, K1A 0C8 and must be received by June 23, 2000 to receive full consideration. All representations should cite the Canada Gazette Part I Notice publication date, title and the Notice reference number DGTP-003-2000.

Respondents are strongly encouraged to provide their comments in electronic format (WordPerfect Microsoft Word, Adobe PDF or ASCII TXT) to facilitate posting on the Department's web site. Documents submitted via electronic media should be sent to the following address:

1.0 Introduction

The purpose of this paper announced in Gazette Notice DGTP-003-00, is to advance spectrum utilization policy decisions and to invite public comments on spectrum policy proposals that address the use of the radio spectrum in the 2285–2483.5 MHz frequency range. Portions of this frequency range are currently designated to the fixed service and mobile aeronautical telemetry service (MATS). Recently, a number of issues pertaining to the use of this frequency range have emerged, including the Canada/US agreement concerning the technical conditions for the implementation of the US Digital Audio Radio Service (DARS) by satellite in the band 2320–2345 MHz, and an increasing demand to permit licence-exempt1 microwave transmitters using directional antennas and spread spectrum techniques in bands above 2400 MHz. Due to these and other issues, the Department has decided to put forward for discussion a number of amendments to the SP 1–20 GHz, in the 2285–2483.5 MHz frequency range.

2.0 Background

In January 1995, Industry Canada released a spectrum utilization policy, entitled Revisions to Microwave Spectrum Utilization Policies in the Range of 1–20 GHz (SP 1–20 GHz), that made substantial spectrum policy provisions to the microwave frequency bands in the 1–20 GHz range. This document established new policy directions to accommodate increasing new spectrum demand by existing and emerging services, addressed the move to digital facilities, and provided greater flexibility for both service providers and equipment manufacturers to access the frequency spectrum.

In August 1997, a public consultation paper, entitled Proposals to Provide New Opportunities for the Use of the Radio Spectrum in the 1–20 GHz Frequency Range (DGTP-006-97), was released to address new proposals for the use of the microwave spectrum in the 1–20 GHz range and to announce some policy decisions which were consequential to certain revisions to the Canadian Table of Frequency Allocations. In August 1998, Industry Canada announced a spectrum policy, entitled Spectrum Policy and Licensing Provisions for Fixed Wireless Access Systems in Rural Areas in the Frequency Range 3400–3700 MHz (DGTP-013-98) which represented the first set of amendments to the 1–20 GHz policy. In June 1999, Industry Canada also announced a spectrum policy, entitled 2500 MHz Multipoint Communications Systems - Policy and Licensing Procedures (DGRB-006-99). Most recently, Industry Canada announced a spectrum policy, entitled Amendments to the Microwave Spectrum Utilization Policies in the 1–3 GHz Frequency Range (DGTP-006-99) which addressed several of the 1–20 GHz proposals. The proposed modifications to the spectrum utilization policy discussed in this paper will be finalized and published within the Department based on the results of this consultation.

Recently published policy documents and activities in Canada and the U.S. have directly impacted the use of the band 2285–2483.5 MHz in Canada. This includes Industry Canada's December 1997 release of a public consultation paper, entitled Multipoint Communications Systems (MCS) in the 2500 MHz Range: Spectrum and Licensing Policy Discussion Document (DGRB-007-97). This paper announced a moratorium on the authorization of all fixed systems in the band 2500–2596 MHz. This band overlaps the upper portion of the frequency spectrum in the band 2520–2590 MHz which is paired with the band 2290–2360 MHz. In addition to this, the U.S. Federal Communications Commission (FCC) has licensed wireless operators for two new services: Digital Audio Radio Service by satellite (satellite DARS) in the band 2320–2345 MHz and Wireless Communications Services (WCS) in the bands 2305–2320 MHz and 2345–2360 MHz.

Table 1 below summarizes the current Canadian fixed and mobile use of the band 2285–2500 MHz, as given in SP 1–20 GHz. It should be noted that:

  1. Low power devices such as digital cordless phones and devices using spread-spectrum techniques are permitted to operate on a licence-exempt basis in the band 2400–2483.5 MHz in accordance with Radio Standards Specification 210 (RSS-210), Low Power Licence-Exempt Radiocommunication Devices (All Frequency Bands) or on a licensed basis in accordance with Radio Standards Specification 139 (RSS-139), Licensed Radiocommunications Devices in the Band 2400–2483.5 MHz;
  2. Industrial, scientific and medical (ISM) radio frequency devices, such as microwave ovens, are extensively used in part of the 2400–2500 MHz frequency range and may be a source of interference to certain services in populated areas.

Table 1 — Current Fixed and Mobile Spectrum Utilization 2285–2500 MHz


1 Licence-exempt devices are radio apparatus which are exempt under the Radiocommunication Act from the requirement to operate under a radio licence in specified radio frequency bands and which conform to appropriate Industry Canada spectrum policies, regulations and technical standards.
