The International Amateur Radio Union (IARU) is a federation of national associations of certified radio amateurs, representing over 150 countries and separate territories around the world.

The three IARU Regions are organised to broadly mirror the structure of the International Telecommunications Union (ITU) and its related regional telecommunications organisations. The Regions comprise:
- IARU Region 1: Europe, Africa, the Middle East and Northern Asia
- IARU Region 2: The Americas
- IARU Region 3: Asia-Pacific

The IARU represents the interests of the Amateur Radio Service worldwide to relevant international organisations, promoting the interests of amateur radio and seeking to protect and enhance its spectrum privileges.

A new footnote allocates this band to the amateur and amateur-satellite services on a secondary basis.

Relevant footnote

In the European Common allocation Table:

EU35: The band 75.5-76 GHz is in Europe also allocated to the Amateur and Amateur Satellite services.

Provided countries recognise EU35, amateur activities can therefore continue in the 75.5-76 GHz band after 2006.

Note: The band 76-77 GHz includes automotive cruise control radar and that 79 GHz (77-81) has been designated as the long term band for wideband automotive short range radar (SRR79G) - which resulted in EU35 being granted

EU17 In the sub-bands 3 400 - 3 410 MHz, 5 660 - 5 670 MHz, 10.36 - 10.37 GHz, 10.45 - 10.46 GHz the amateur service operates on a secondary basis. In making assignments to other services, CEPT administrations are requested wherever possible to maintain these sub-bands in such a way as to afcilitate the reception of amateur emissions with minimal power flux densities.

EU23 In the sub-bands 5 660 - 5 670 MHz (earth to space), 5 830 - 5 850 MHz (space to earth) and 10.45 - 10.50 GHz the amateur-satellite service additionally operates on a secondary and non interference basis to other services. In making assignments to other services, CEPT administrations are requested wherever possible to maintain these allocations in such a way as to facilitate the reception of amateur emissions with minimal power flux densities.

3 300 - 3 500 MHz

 

The 9 cm band

This bandplan is the simpliefied version, without the footnotes. If you want to have the fully detailed bandplan please refer to the VHF managers Handbook

IARU Spectrum Requirement

The amateur service seeks the retention of the secondary allocations of the band 3 300 – 3 500 MHz in Regions 2 and 3, and a secondary allocation throughout Region 1. Further, the amateur service seeks upgrading the allocation status of the sub-band 3 400 – 3 410 MHz to primary. The amateur-satellite service seeks to retain its bi-directional (Earth-to-space and space-to-Earth) allocation of the band 3 400 – 3 410 MHz in Regions 2 and 3, and to expand this allocation to Region 1.

CEPT DSI Phase I considered an Amateur Service secondary allocation at 3400-3500 MHz. As a result, the following footnote was adopted by the CEPT:

EU17: In the sub-bands 3 400 - 3 410 MHz, 5 660 - 5 670 MHz, 10.36 - 10.37 GHz and 10.45-10.46 GHz the amateur service operates on a secondary basis. In making assignments to other services, CEPT administrations are requested wherever possible to maintain these sub-bands in such a way as to facilitate the reception of amateur emissions with minimal power flux densities.

In effect, EU17 allocates 3 400 - 3 410 MHz for amateur use in Europe and encourages administrations to afford some consideration to amateur weak-signal operations in the band.

There has been a major effort by the telecommunications industry to promote the band 3 400 - 3 800 MHz for wireless access applications. WRC-07 identified the band 3 400 - 3 500 MHz for IMT applications in certain countries, which poses an additional difficulty for the Amateur Services in achieving improvement in the band 3 400 - 3 410 MHz with respect to upgrading the allocation or extending the allocation to Region 1.
