Limit on assignments in VHF and UHF bands

This business operating procedure applies to narrowband VHF or UHF single-channel links. It limits the number of links in 12.5 kHz and 25 kHz bands that can be assigned to an operator for use between the same two sites.

We cannot assign more than 5 single-channel (12.5 kHz and 25 kHz) VHF or UHF fixed links to a link operator for co-path use.

If you need more than 5 channels, use alternative point-to-point spectrum in the microwave bands. This option is better for supporting wideband or multi-channel operation.

Reasons for the assignment limit

Demand for single-channel fixed-link use continues to grow. This has led to congestion in the spectrum in some areas.

This limit on the maximum number of co-path links ensures:

  • fair access to the limited amount of single-channel link spectrum
  • use of the single-channel link bands meets their intended purpose

This business operating procedure continues the restriction that started with RALI FX4. RALI FX4 ended in 2012.
