1. Intent

The purpose of this document is to specify the spectrum usage policy for the 8275-8500 MHz band by the fixed service.

2. Introduction

On the basis of a submission in 1988 by the Radio Advisory Board of Canada, (RABC) the Department has reviewed its spectrum policy for the 8275-8500 MHz band. This policy was last revised in 1984 after a request for public comment in the Canada Gazette to, among other things, consider the removal of one-hop systems from this band to prevent the blockage of growth of multi-hop systems. While the one-hop restriction was agreed to and adopted, its application to one-hop spurs from relay systems operating in other bands had not been fully considered, and users of the band found themselves restricted in an unforeseen way.

During the review of this matter, it was found there continues to be substantial growth in the band, for the most part by multi-hop systems in support of cable television undertakings. The other use of the band of any significance is to provide video program feeds to broadcast stations. This latter use has been much less substantial, presumably because other long distance transmission modes are being used such as satellite or common carrier facilities in other bands.

Although the restriction on one-hop spurs was intended to protect the growth of multi-hop systems, it has been argued by the RABC that lifting the restriction on spurs carrying cable signals would cause little constraints on most new multi-hop systems. This is because cable operators tend to share such facilities and therefore such conflict is less likely to arise in any particular geographical area. If it does, it should be easily resolved because the parties are of a community of common interest. Retention of the restriction for non-cable associated use should not cause significant hardship because the demand for such use is relatively small.

Multi-hop Video (MHV) in 8275-8500 MHz band

1. In order to relieve frequency congestion and provide adequately for MHV services, one-hop systems and, except as noted below, one-hop spurs from systems operating in other bands are designated non-standard in the 8275-8500 MHz band.


2. When used for CATV applications, one-hop spurs from systems operating in other bands can be authorized on a standard basis.

3. The carriage of wideband radar (37.5 MHz maximum bandwidth) will be considered on a case-by-case basis on the understanding that suitable bandwidth reduction techniques will be employed as they become feasible.

4. Digitized video systems will be assigned in this frequency band if the RF bandwidth does not exceed 18.75 MHz.

5. Use of the fixed-satellite service in this band is restricted to the Government of Canada. Co-ordination is required.
