The contours of the map are for rain-rate (mm/h) exceeded for 0.01% of time. The map is positioned in relation to the UK according to the following co-ordinates:
The map of UK rain rates is constructed from British Atmospheric Data Centre and ITU data. A full explanation is given in (legacy) paper RSSP(05-01)/42, available from Ofcom on request.
UK Microwave Link Planning
Planning of Microwave Links requires understanding of Microwave Propagation. For frequencies above 10GHz, rain fade is significant and needs to be taken into account. Modern Microwave Planning tools can incorporate this data and calculations to achieve Availability Calculations for microwave links deployed in all regions worldwide.
Data is from regulator OFCOM document: “OfW 446: Technical Frequency Assignment Criteria for Fixed Point-to-Point Radio Services with Digital Modulation “
31GHz and 38GHz bands are used for Point to Point (P2P) Microwave Radio Links

Technical regulations
The Radio Equipment and Telecommunications Terminal Equipment Directive
99/5/EC (R&TTED) has been implemented in ‘The Radio Equipment and Telecommunications Terminal Equipment Regulations 2000, Statutory
Instrument (SI) 730. In accordance with Articles 4.1 and 7.2 of the R&TTED
the:
• IR2000: The UK Interface Requirement 2000 contains the requirements for the licensing and use of fixed (point-to-point) wireless services in the UK.
• IR2037: The UK Interface Requirement 2037 applies for scanning telemetry services.
• IR2078: The UK Interface Requirement 2078 applies for the 60 GHz band
Notes specific to the frequency charts
The first column describes each available frequency band, represented by a diagram (not to scale). The frequency band limits are listed below the diagram; frequencies below 10 GHz are represented in MHz, while those above 10 GHz are in GHz. The width of each guard band is shown above the diagram, and is always specified in MHz.
The channel arrangements in some bands are staggered, so that the width and position of the guard band vary for different channel spacings. In these cases, a table underneath gives details of the guard bands for different spacings (with all frequencies in MHz).
The first column also includes the title of the relevant international recommendations for each band, produced by the European Conference of Postal and Telecommunications (CEPT) or the International Telecommunication Union (ITU). CEPT recommendations are available at https://www.cept.org/ecc/ and ITU Recommendations at https://www.itu.int.
The final column contains the channel spacing for duplex operation in each frequency band except for bands above 60 GHz. Details of standard systems assigned in the UK are shown in the relevant technical frequency assignment criteria.
