Technical Committee (TC) Broadband Radio Access Networks (BRAN) Activity Report 2021

Chair: Guido Hiertz, Ericsson GmbH, Eurolab

Responsible for the standardization of present and future Broadband Radio Access Networks. 

Our Broadband Radio Access Networks committee (TC BRAN) produces and maintains standards and specifications for current and future Wireless Access System (WAS) and Radio Local Area Network (RLAN) technologies in different frequency ranges. The committee has primary responsibility for all aspects of standardization for broadband radio access networks, including systems as defined in ITU-R Recommendation F.1399-1.

In July 2021 TC BRAN published a revision of its Harmonised Standard EN 302 567 V2.2.1 on access to radio spectrum for equipment operating in the 60 GHz band. The revision considers the inclusion of receiver sensitivity requirements. As of end 2021, the updated standard is awaiting citation in the Official Journal of the EU.

Development and/or revision of further Harmonised Standards for access to radio spectrum continued, covering:

  • EN 303 687 - Wireless access systems including radio local area networks (WAS/RLANs) operating in the license-exempt 6 GHz band. In 2021, TC BRAN resolved almost all outstanding aspects for this draft standard. Because of the good progress, HASTAC assessment is expected for 2022.
  • EN 301 893 – RLANs operating in license-exempt 5 GHz bands. TC BRAN has significantly improved the draft. HASTAC assessment is expected for 2022.
  • EN 301 598 - White Space Devices (WSD) operating in the 470 MHz to 790 MHz TV broadcast band. TC BRAN submitted version 2.2.0 of the HS for ENAP, which will close in March 2022.
  • EN 303 722 - Wideband Data Transmission Systems (WDTS) for fixed network radio equipment in the 57 GHz to 71 GHz band. TC BRAN resolved all comments received during 1st ENAP on this HS. 2nd ENAP on version 1.2.0 of the HS will close in March 2022.

TC BRAN also submitted its TS 103 754 for final remote consensus. This Technical Specification provides a set of test cases for performance testing (coverage, throughput, roaming time, etc.) of Access Point (AP) deployments in wireless mesh networks.

Further progress was also made on a Technical Report, investigating the feasibility of applying new and existing mitigation techniques to systems including radio local area networks (WAS/RLAN), radar and RTTT/smart tachographs to enable coexistence in the 5 725 MHz to 5 850 MHz band.

From ETSI ERM TG41, TC BRAN took over responsibility for Harmonised Standard EN 303 258, addressing Wireless Industrial Applications (WIA) operating in the 5.8 GHz band.
