3300-3500 MHz


The 9 cm band

The amateur service seeks the retention of the secondary allocations of the band 3300 – 3500 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 3400 – 3410 MHz to primary. The amateur-satellite service seeks to retain its bi-directional (Earth-to-space and space-to-Earth) allocation of the band 3400 – 3410 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 3400-3410 MHz, 5660-5670 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 3400-3410 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 3400-3800 MHz for wireless access applications. WRC-07 identified the band 3400-3500 MHz for IMT applications in certain countries, which poses an additional difficulty for the Amateur Services in achieving improvement in the band 3400-3410 MHz with respect to upgrading the allocation or extending the allocation to Region 1.
