Categories of Services:
- Services the names of which are printed in capital letters, (e.g. FIXED) are primary services.
- Services the names of which are printed in normal characters, (e.g. Fixed) are secondary services.
- Stations of a secondary service:
- shall not cause harmful interference to stations of a primary service to which frequencies are already assigned or to which frequencies may be assigned at a later date;
- cannot claim protection from harmful interference from stations of a primary service to which frequencies are already assigned or may be assigned at a later date;
- can claim protection, however, from harmful interference from stations of the same or other secondary service(s) to which frequencies may be assigned at a later date.
Antenna Directivity and Polarization — With the exception of point to multipoint links, all other fixed point to point links must use directional antennas with a minimum gain with respect to half wave dipole of 9 dB in the VHF band (30–300 MHz) and 12 dB in the UHF band (above 300 MHz). Lower gain antennas may be permitted where they provide equivalent re-use of frequencies through control of front-to-back ratio. In order to use a common frequency for all links within a point to multipoint system, omnidirectional or other antenna patterns with large beamwidth would be permitted for such applications on a secondary basis, as long as the re-assignment of the same frequency is not affected due to the use of the non-directional antenna. Antennae horizontally polarized must be used in all cases unless operational requirements justify vertical polarizaiton.
Bandwidth Considerations — Within the single normal mobile channel spacing used in the band under consideration, one or more discrete frequencies or multiplexed channels may be employed, provided that the total emission bandwidth can be accommodated. As noted in Section 3.3, contiguous bandwidths in excess of a single normal mobile channel but less than 90 kHz may be employed below 890 MHz only in areas of light mobile use.
Single voice channel FM or PM equipment shall meet the requirements specified in Radio Standards Specifications (RSS) 119 (and its Supplement if applicable). Equipment using modulation techniques other than FM or PM or using multiplex channels within a single normal mobile channel bandwidth will be certified in the interim using RSS 119 as a guide, on the basis of the engineering brief submitted; until such time as specifications are developed for such equipment.
Number of Hops — There are no restrictions on the number of hops to be authorized. They should be based on the type of service (e.g. paging or two-way system), proposed system configuration and availability of spectrum. Also, systems requiring multiple hops should be designed to optimize spectrum utilization.
Effective Radiated Power and Antenna Height — The effective radiated power (ERP) will be limited to that necessary to provide the required service as governed by the system requirements. To this end, restrictions will be applied to the ERP, antenna polarization/antenna directivity and antenna height above ground level.

Note: Radio linking is permitted in the band 216–220 MHz only in areas 170 km from navigable Canadian waters.
1 Frequency bands 73–74.6 MHz, 74.8–75.2 MHz and existing model control frequencies are not available for fixed links. Consideration in making fixed assignments in this range may have to be given to protection of reception of TV channels 4 and 5.
2 Frequency bands 156.7625–161.535 MHz, 409–410/420–421 MHz, 421.0–422.175 MHz, 426.0–427.175 MHz, 425.0–426.0 MHz, should be avoided for fixed links.
3 In order to avoid any compromise with the development of mobile services in the band 806–890 MHz, no fixed links will be authorized in this band in the areas of intensive and moderate mobile use.
