ERM Activity Report 2017
Chairman: Holger Butscheidt, Ministry of Economics and Technology, Germany
Responsible for a range of radio product and electromagnetic compatibility (EMC) standards and the overall co-ordination of radio spectrum matters
In 2017, ETSI’s EMC and Radio Spectrum Matters committee (TC ERM) continued to focus on the introduction of the new Radio Equipment Directive (RED) which replaced the Radio and Telecommunications Terminal Equipment (R&TTE) Directive in June 2016, subject to a one year transition period. For many years TC ERM has provided more than 75% of the Harmonised Standards required under the R&TTE Directive. The new RED has implications for ETSI’s radio work, especially in relation to receivers, software defined radio and cognitive radio. After review and alignment, TC ERM is currently maintaining nearly 150 Harmonised Standards related to the Radio Equipment Directive. This work dominated activities in 2017.
In addition, since the scope of the RED is broader than the R&TTE Directive, TC ERM continued to develop new Harmonised Standards in areas such as radio and TV broadcast receivers, equipment below 9 kHz and radio determination equipment which were not addressed by the R&TTE Directive.
To assist radio groups in defining new receiver parameters a Special Task Force has been established to investigate and describe a new concept of signal interference handling in a Technical Specification (TS) and a Technical Report (TR). Co-ordinating its work with other ETSI radio groups, TC ERM works on revisions to all parts (currently more than 50) of the existing EMC multipart Harmonised Standard and is developing new EMC Harmonised Standards for equipment not covered under the R&TTE Directive, but which is now under the scope of the RED. This includes, for example, Digital Enhanced Cordless Telecommunications (DECT™), certain marine equipment, Private Mobile Radio (PMR)/Terrestrial Trunked Radio (TETRA), fixed link equipment, medical applications, Short Range Devices (SRDs) and Ultra Wide Band (UWB) equipment. This work is being carried out in close co-operation with the European Committee for Electrotechnical Standardization (CENELEC) to avoid the duplication of effort. In addition, work continued on the development of two Harmonised Standards for the EMC of combined and/or integrated equipment for industrial and residential locations.
TC ERM is responsible in ETSI for issues relating to spectrum usage. Work continued on updating the TR which includes detailed information on spectrum use and an overview of ETSI standards, reports and specifications, together with their applications and relevant frequency bands.
In the area of measurement uncertainty, work progressed with the preparation of a new TR on the use and effect of mathematical operations on relative measurement uncertainties. One practical application of this work will be the evaluation of measurement uncertainties associated with the radiated measurement of the output power of a base station already in operation in a public network. The committee also finalized its TR on definitions of radio parameters in ETSI standards, specifications and reports, harmonising the definitions.
New work started on a TR to provide to ETSI technical groups information on the use of measurement detectors (e.g. quasi peak, RMS, average, peak) in radio measurement methods.
In the broadband radio access networks area, TC ERM initiated two System Reference documents (SRdocs): one on wireless access systems including radio local area networks (WAS/RLANs) in the band 5 925 MHz to 6 725 MHz, and one on multiple gigabit wireless systems (MGWS) in radio spectrum between 57 GHz and 71 GHz. While the first one is a request to extend the already existing band for WAS/RLANs, the second SRdoc proposes the outdoor usage for MGWS as well as to move the existing mmW-ITS allocation to a single MGWS channel.
TC ERM started a further update of the European Standard (EN) for 2,4 GHz wideband transmission systems. This includes to improve of the resilience to blocking for devices for uses which have the greatest risk of suffering interference from future deployments e.g. LTE™ in the adjacent bands, to consider further the definitions of categorization of receivers, to improve the test methods or to include alternative test methods as appropriate and to review the measurement uncertainties.
To take account of the RED, the committee revised the Harmonised Standards for cordless audio devices up to 2 000 MHz, wireless microphones, audio Programme-Making and Special Events (PMSE) up to 3 GHz, inductive loops for the hearing impaired in the 10 Hz - 9 kHz band which have been published by the beginning/mid of 2017 Work is still ongoing on the Harmonised Standard for Wideband Audio Links, expected to be completed end of 2018, while new work has started to revise the Harmonised Standards for Wireless Microphones, Audio PMSE up to 3 GHz.
TC ERM developed a new SRdoc on wideband multichannel audio systems in the 25 MHz - 3 GHz band, which was published mid of 2017. In October 2017 work on a revision of the SRdoc on Audio PMSE systems in the frequency range 25 MHz to 3 GHz was initiated to update the current version of the SRdoc with new technology including conference and other systems.
Throughout the year TC ERM continued work on broadcasting equipment, developing Harmonised Standards for radio and TV broadcast receivers, as well as transmitting equipment for Digital Radio Mondiale broadcasting and Terrestrial - Digital Audio Broadcasting (T-DAB). The publication of Harmonised Standards for TV broadcast transmitters, amplifiers for TV broadcast reception in domestic premises, as well as for the Frequency Modulated (FM) and Amplitude Modulated (AM) sound broadcasting service took place mid of 2017.
In the area of satellite earth stations and systems, the committee finalized a revised version of the SRdoc on non-geostationary orbit (NGSO) earth stations in the Ku band. This will provide information on Earth stations communicating with NGSO satellites in the 11 - 14 GHz frequency band.
An SRdoc on wireless power transmission systems for WPT operating below 30 MHz has been developed with the intention to publish in 2018. The committee finalized work on a new Harmonised Standard on wireless power transmission, with publication in September.
In 2017 work on Low Throughput Networks (LTNs) continued with a TR on use cases and system requirements, along with two TSs for the LTN architecture and the protocols for LTN interfaces, with the TR being published in October.
All of TC ERM’s Harmonised Standards for generic SRDs required revision to align with the RED. By February/March 2017 most of them were published, and for three of them revisions were initiated prior to final EN approval.
Work on three new Harmonised Standards for equipment operating below 9 kHz continued. The Harmonised Standards on generic equipment as well as metal sensors were under development, while the Harmonised Standard on robotic mowers was published in September. In addition, TC ERM completed a Harmonised Standard for social alarm equipment in the 25 - 1 000 MHz band, published in February.
Work continued on Harmonised Standards for railway systems and avalanche beacons, with publication expected by mid-2018.
Work was finalized on a SRdoc for Ultra Narrow Band SRDs in the band below 1 GHz with publication in February. At the same time work was initiated on two new SRdoc for Low Power Wide Area Networks Chirp Spread Spectrum (LPWAN-CSS) operating in the UHF spectrum below 1 GHz and SRD equipment using Nuclear Magnetic Resonance (NMR) technology in the frequency range 1 MHz to 50 MHz. Both were scheduled for completion at the beginning of 2018.
The committee made good progress on Harmonised Standards for wireless medical devices and published a Harmonised Standard on Ultra Low Power Active Medical Implants (ULP-AMI) in 30 MHz to 37,5 MHz in January, directly followed by the start of a revision currently in drafting stage. The two Harmonised Standards on Paging Service in 25 MHz to 470 MHz and on Ultra Low Power Animal Implantable Devices (ULP-AID) in 315 kHz to 600 kHz were published in June and October respectively.
Work was started on a new Harmonised Standard on wideband Ultra Low Power wireless medical capsule endoscopy in the UHF band, targeting publication in April 2018.

The committee started work on a new TS to evaluate necessary changes for a further revision of the Harmonised Standard on measurement techniques for SRs) using Ultra Wide Band UWB.
TC ERM and ETSI’s Mobile Standards Group (TC MSG) co-operate in a joint Task Force for Harmonised Standards for International Mobile Telecommunications (IMT) (TFES). In 2017 TFES continued to work primarily on a revision of the multipart Harmonised Standard on base stations and user equipment for IMT-2000 third generation cellular networks to ensure compliance with the RED. In addition TFES published its TS and the corresponding Harmonised Standard on mobile communication on board aircraft systems.
We updated the Harmonised Standards on the Advanced Surface Movement Guidance and Control System for air traffic management equipment (A-SMGCS), including the new Part 5 on multilateration equipment. Work started an update of the Harmonised Standards for VHF Digital Link Modes 2 including a TR on data link improvements.
The committee’s main aeronautical work in 2017, however, related to the RED and the need to address the standardization of communications, navigation and surveillance equipment, such as radar, aspects of which were not covered under the R&TTE Directive. This work included updates to existing standards for meteorological aids, for Ground Based Augmentation System VHF ground-air data broadcast, and for ground-based VHF/UHF radio transmitters, receivers and transceivers for the aeronautical mobile service, which partially have been published.
In addition, we continued work on three Harmonised Standards required under the scope of the RED, addressing, respectively, primary surveillance radar (PSR) in three operational bands, secondary surveillance radar and multi-static PSR. The group continued work on four Harmonised Standards for meteorological radar in three operational bands, and air traffic control surveillance and started work on a Harmonised Standard for Data Link Services (DLS) System.
Work continued on a TR on the use of professional unmanned aerial systems in Europe for civil use such as by film crews, for aerial surveys and by the police. This was expected to be completed in February 2018.
