Where does the action take place?

ERC Recommendation Annex 5 - Clarifications -This annex covers frequency bands and regulatory as well as informative parameters recommended for radio systems used in the field of transport and traffic telematics (road, rail and water depending on the relevant technical restrictions), traffic management, navigation and mobility management. Typical applications are used for interfaces between different modes of transport, communication between vehicles (e.g. car-to-car), between vehicles and fixed locations (e.g. car-to-infrastructure), communication from and to users as well as radar system installations. Automotive radar is defined as a moving radar device supporting functions of the vehicle. -Note that the regulation in the bands d1) to d5) for the band GHz for automotive radars is without any plans for a time limit within CEPT (see document ECC(15)058). Only the bands 21.65GHz GHz and 24.25GHz GHz for Short Range Radar (SRR) are time limited – clarification added.

On-going Activities in Europe for TTT New ECC Decision (16)02 on rotorcraft anti-collision radars operating in GHz approved for publication on 4 March 2016 Be aware that GHz includes automotive radars, infrastructure radars in the current regulation; it’s also used at railway level crossings or airplanes during taxiing Still on-going compatibility studies in CEPT between automotive and fixed infrastructure radars (incl. ETSI creating new harmonised standard for fixed infrastructure radars) Harmonisation of MHz (in addition to MHz) proposed in Draft CEPT Report 59 (in public consultation, 6th Update of the EC Decision for SRDs). Most road tolling networks already have been implemented within MHz in most European countries, based on the original ERC Decision from In addition, ECC Report 244 already indicates several possible solutions for compatibility between RLAN and road tolling in the band MHz. Note the 5 GHz mandate from the European Commission to CEPT. New applications to be investigated in near future: Mobile road tolling enforcement, eTachograph, Weight and Dimensions (lorries) as part of the next update. Road tolling needs to become more robust.

On-going activities in Europe for ITS (Intelligent Transportation systems) Revision of ECC Decision (08)01 and ECC Recommendation (08)01 was published in 07/2015 : Target: unwanted emission limits and mitigations with regard to road tolling ITS not restricted to road vehicles Split into channels with a bandwidth of 10 MHz each CEPT administrations shall exempt ITS equipment falling under this Decision that complies with EN from individual licensing. Equivalent mitigation techniques, as defined in the relevant harmonised European standard ETSI EN , also be used. Regulators consider other transportation applications should share the ITS frequencies such as Urban Rail Systems (based on an analysis in progress – looks like it could be possible) – also perhaps relevant for future ITS applications-> driverless vehicles / autonomous systems Frequency rangeUsageRegulation MHz to MHzFuture ITS applicationsECC Decision (08) MHz to MHz ITS safety (not limited to road safety!)

63-64 GHz Revision of ECC Decision (09)01 – ITS in GHz approved for publication on 4 March Identified since 1992, covered by ‘ITS regulation’ but can also be used by sensors including hybrid radar and vehicle communications systems Harmonised in EC Decision for SRDs and ECC Decision (09)01 No implementations (or near future) implementations in the market known (although there is a work item for revision of the harmonised European standard and information in ITU-R) Competing interests (e.g. unlicensed FWA) -> the band is available worldwide under general authorisations – the whole range GHz under investigations worldwide also as ‘5G’ possibility (also FCC, this action will provide more spectrum for unlicensed uses such as Wi-Fi-like “WiGig” operations). CEPT looking into possibilities for ‘relaxed’ regulations for unlicensed devices in GHz (some countries in Europe don’t have Fixed Service in this range).

Status in Frequency regulation ITS entries in frequency tables recognised as application in the mobile service (5.9 GHz, GHz) All other entries recognised as ‘short range devices’, under Art. 4.4 of the Radio Regulations, i.e. no protection status, no connection to any radio service allocation World Radio Conference 2015 Agenda item 1.18 agreed a primary allocation to the radiolocation service for automotive applications in the GHz frequency band in accordance with Resolution 654 (WRC-12). Question under discussion: Need to revise ECC Decision (04)03 (Automotive Short Range Radars in band GHz)?? Risks are to re-open discussions about protection of the radio astronomy service-> exclusion zones, automatic deactivation SRD status also provides an advantage: issues not linked to WRC (more flexible) ‘De-facto protection’ when importance in the market (see road tolling) – new applications would need to protect SRR anyway (otherwise, it would create an implementation issue). WGFM#84 (February 2016) tasked the SRD/MG to continue with the revision making of ECC Decision (04)03 for GHz automotive short range radars and sent a liaison statement to ETSI on this matter.

RLANs in vehicles SRD/MG delivered in May 2015 a first analysis which was endorsed by WGFM. The usage of current SRD regulation is recommended. Further investigations about a European 'ISM mode' in MHz needed. WG FM#84 (February 2016) decided to task the SRD/MG to consider developing clarifying language until the WG FM meeting in May 2016 on the use of the frequency band 5725–5875 MHz for SRD/RLAN operation (max. e.i.r.p. = 25 mW) on-board aircraft in ERC Recommendation to satisfy short term needs of the civil aviation sector (this may also be relevant for other areas, such as usage in cars, trains etc.). The considerations may also include discussions on indoor equivalent use on-board trains or vehicles. Difficulties with DFS (Dynamic Frequency Selection) mechanism.

Agenda Item 1.12 to consider possible global or regional harmonized frequency bands, to the maximum extent possible, for the implementation of evolving Intelligent Transport Systems (ITS) under existing mobile-service allocations, in accordance with Resolution COM6/13 (WRC-15); Came in as proposed by APT Invitation (new Resolution) taking into account the results of ITU-R studies on sharing and compatibility between passive and active services as well as spectrum needs for those services, to consider identification for use by administrations for the land-mobile and fixed service applications operating in the frequency range GHz, while maintaining protection of the passive services identified in No , and take appropriate action; APT updated work plan on SRDs (looking into potential bands above 275 GHz for SRD usage); development of an APT Report for this purpose; CEPT may do something similar (at the moment, the following ISM bands GHz and GHz are already identified) – will be put on the agenda in CEPT Agenda for the 2019 World Radiocommunication Conference
