Radio equipment list (REL)
The Radio Equipment List (REL) is an Innovation, Science and Economic Development Canada publication, listing radio equipment which has been certified for use in Canada.
Certification of radio equipment means that the equipment complies with established Radio Standards Specifications (RSS) requirements, in accordance with Radio Standards Procedure (RSP). A "Technical Acceptance Certificate" is issued accordingly. A licence to operate the equipment, where applicable, is required separately and is granted solely on the basis of the existing radio environment, type of service and location of operation.
The frequency range of equipment approved under some specifications may be beyond the frequency range of a specific application. Frequency assignments are controlled by the Department through the licensing process.
Description of Technical Terms
1. Occupied bandwidth and type of emission — The necessary bandwidth and type of emission is indicated as described by the International Telecommunications Union (ITU).
2. Power — The RF power output is indicated in various orders of magnitude of the unit of Watt. For single-sideband suppressed carrier emissions, the power is expressed as Peak Envelope Power (PEP); for single-sideband full carrier emissions, the power is expressed as carrier power (one quarter of the PEP referred to above).
3. Frequency range — This is the range of frequencies over which the equipment is designed to operate and shows the low and high limits respectively. Where only one frequency is indicated, that particular equipment was certified to operate on a specific frequency. The frequencies are indicated in various orders of magnitude of the unit Hertz.
