Subject: Proposed future 32GHz capacities and bandwidths.

Background
In preparation for opening the 32GHz band in 2002 it is necessary to modify the Radio Interface Requirement (RIR2000) with the necessary licensable equipment and
antenna options. Following agreement within the FLCC and PPWG the modified regulation will be notified to the European Commission under Directive 98/34/EC. The
channel plan is illustrated in Annex A.
Issue
Within the UK discussions are on-going with respect to the shared use of the band by the Radionavigation Service. Furthermore the band was previously allocated to
Short-Range Devices (SRDs) and under the UK Spectrum Strategy, all SRDs are to be taken out of operation by December 2003.
WRC-03 Agenda Item 1.8.2 could affect on the development of the band. One of the items being the consideration of passive services in adjacent the 31.5-31.8 GHz band.
This may have some impact on the 32 GHz band.
Proposal
Based on the results of the UK consultation and taking into account the on-going issues that need to be finalised, RA is proposing a staged release of the 32 GHz band. It is
clear from the current requirement of UK operators that new spectrum will be required for point-to-point applications (ref. results of the recent 3G questionnaire). On this
basis and taking into account the current requirements and future possible requirements, RA proposes to release one-third of the paired available spectrum in the upper part of
the sub-bands to meet the expressed requirements for point-to-point applications in the UK. This spectrum will be administered through the RA’s fixed link assignment tool
(FiLSM). The remaining lower two-thirds of the sub-bands will be held back for future possibilities.
Note: There is a strong argument for assigning only spectrally efficient equipment in the 32GHz band. These are shown in table 1.

Additional Information
Currently, assignments are available in
the upper third of the two sub-bands
(32319 – 32571MHz
