CEPT Report 54 - Executive Summary - Harmonised Technical Conditions for 1452-1492 MHz WBBSDL

Sep 10, 2026

This CEPT Report responds to the European Commission mandate to develop harmonised technical conditions for wireless broadband electronic communications services in the 1452–1492 MHz frequency band. The analysis evaluates regulatory frameworks and concludes that harmonisation for wireless broadband supplemental downlink (WBBSDL) offers the highest benefits, while permitting national adaptation in parts of the band. The report details channelling arrangements and least restrictive common technical conditions to support coexistence in adjacent bands, including EU outer borders, and addresses national measures for coexistence with uncoordinated fixed links.

CEPT Report 54 Report from CEPT to the European Commission in response to the Mandate “To develop harmonised technical conditions in the 1452-1492 MHz frequency band for wireless broadband electronic communications services in the EU” Report approved on 28 November 2014 by the ECC 0 EXECUTIVE SUMMARY This CEPT Report is the response to the Mandate issued by the European Commission to develop harmonised technical conditions in the 1452-1492 MHz frequency band for its use for wireless broadband (WBB) electronic communications services in the EU. The Report is based on the impact analysis carried out by CEPT aimed at determining the regulatory framework that will bring the highest benefits to the future harmonised use of the 1452-1492 MHz in Europe. In that respect, the conclusion of this analysis is that the most appropriate regulatory framework for the future use of the 1452-1492 MHz band is its harmonisation for wireless broadband supplemental downlink (WBBSDL), while allowing individual countries to adapt to specific national circumstances in part of the band for terrestrial broadcasting and other terrestrial applications. This regulatory framework is found to bring the highest benefits to CEPT. The harmonisation of the 1452-1492 MHz band for WBB SDL is important to enhance the downlink capability of mobile broadband systems and represents a strategic tool to tackle the growing mobile data traffic asymmetry driven by increased mobile multimedia usage. WBB technologies such as UMTS and LTE have already evolved to be capable of using unpaired spectrum, including 1452-1492 MHz, for SDL, and such capability has already been incorporated in the international standards developed by 3GPP. This CEPT Report provides the harmonised technical arrangements and conditions for WBB SDL-based use of the 1452-1492 MHz, namely the channelling arrangement, the common and minimal (least restrictive) technical conditions, the common technical conditions to ensure coexistence with radio services/applications in adjacent bands, including at the EU outer borders. It is noted that in addition to the harmonised technical arrangements and common conditions, some specific measures can be applied at national level by those administrations that need to enable the use of the 1452- 1492 MHz band for SDL while ensuring coexistence with uncoordinated fixed links. The co-existence with all other radio services/applications considered in adjacent bands, is ensured when appropriate, with relevant coordination procedures for coordinated fixed links (which may include additional technical/operational conditions i.e. frequency-territorial planning depending on national circumstances) and telemetry, with the common harmonised out of band limits defined in this Report. In the case where an Administration uses Terrestrial Digital Audio Broadcasting (T-DAB) in part of the band 1452-1479.5 MHz, coordination thresholds to be used under the Maastricht Agreement have been developed together with, for that Administration, nationally applicable technical conditions to ensure in-band adjacent channel coexistence.
