RALI FX20: Millimetre wave point-to-point (self-coordinated) stations

In March 2025, we released a consultation paper proposing to expand the number of frequency bands included in RALI MS45. Consequently, minor changes were made to RALI FX20 to facilitate the arrangements introduced in RALI MS45, while retaining the self-coordination procedures for prospective PTP services. For more information, see our Updates to earth station and PTP coordination rules outcomes paper.

This RALI deals with point-to-point (self-coordinated) radiocommunications links in:

• 58 GHz (57-59 GHz) band
• 75 GHz (71-76 GHz) band
• 85 GHz (81-86 GHz) band

Radiocommunications Assignment and Licensing Instruction (RALI) FX20 is for accredited persons and licensees. It may also be useful to:

• telco network operators
• people who plan systems
• manufacturers or importers of electrical equipment

It guides you on what to consider when you plan a system to:

• manage interference
• meet domestic and international radiocommunications rules
