Road tolling and Smart Tachographs in 5795-5815 MHz 5795-5815 MHz – currently limited to road tolling applications in Europe New European Legislation for Smart Tachographs published – Introduction in early 2019 Studies in CEPT to include Smart Tachographs in the frequency regulation (EU and CEPT) Smart Tachographs include roadside inspections (vehicle-vehicle and roadside-vehicle) – the studies cover these new use cases Additional studies to take into account road tolling, general RLAN use, RLAN use in cars, ITS in the 5 GHz range to ensure future co-existence (no change of the regulation intended but equipment improvements may be necessary)
RLAN in vehicles – Possibility under the current regulations Explanatory paper published (ref. In ERC/REC 70-03)
ITS and Urban Rail systems Revision of ECC Decision (08)01 and ECC Recommendation (08)01 is intended Urban Rail and ITS to share frequencies (Urban Rail to be under the ITS frequency regulation) Urban Rail CBTC in 5875-5925 MHz – with some focus on 5905-5925 MHz - no application to be excluded from any frequency range Scope/Conditions: under the current coexistence studies (based on IEEE 802.11/11p/ ETSI G5) and focusing on Urban Rail Systems Analysis together with ETSI. A new ECC Report to accompany the revision making of the ECC Decision Technology solution to be found in ETSI Frequency range Usage Regulation 5 905 MHz to 5 925 MHz Future ITS applications ECC Decision (08)01 5 875 MHz to 5 905 MHz ITS safety (not limited to road safety!) ECC Decision (08)01 Commission Decision 5 855 MHz to 5 875 MHz ITS non-safety applications ECC Recommendation(08)01
63-64 GHz Major review started for 57-66 GHz The aim is to find a better harmonisation approach for all applications under general authorisation regime - no indoor restriction anymore. The least restrictive regulation should be achieved, also to provide more suitable possibilities for WiGig and 5G backhauling Quite limited number of licensed FS links, mostly in the range 57-59 GHz More attractive regulatory solutions under general authorisations outside of Europe Modified channelization arrangement for WiGig could take better into account ITS in 63-64 GHz Partition of the spectrum between FS, ITS, and SRD applications under license-exemption under consideration In this context: ITS in 63-64 GHz may be questioned
Sensors 76-77 GHz Studies completed for 76-77 GHz Fixed Radars vs Automotive Radars-ECC Report 262 Regulatory framework will be revised. Aim: Ensure future coexistence conditions Detailed technical parameters (e.g. radar dwell times and duty cycles for fixed radars) maybe best reflected in the harmonised standard (EN 301 091-3 for fixed radars), and that the Rec. 70-03 (an additional paragraph under frequency issues) and the EC Decision for SRDs (referring to the harmonised standard under RE-D or equivalent, possible proposal in the 7th update) refer to the harmonised standard. A solution in the standard alone is not enough since a requirement set out in the standard also needs at least a reference in the regulation Inclusion of the parameters in the standard has the benefit that the parameters will only apply to new products (no issue with ‘grandfathering’ of older fixed radars)
Sensors 77-81 GHz 77-81 GHz has been designated for long term solution in Europe – though 24.05-24.25 GHz -> no time limitation in Europe ECC Decision (04)03 will be reviewed in 2017 (ordinary review – takes place each 5 years – no real changes envisaged yet) Global implementation overview Implemented: CEPT, Marocco, Algeria, Katar, Macao, Malaysia, Singapore, Taiwan, Australia Important countries missing – processes are triggered but no regulation published yet. USA: proposal for rule change – timetable is unclear (some OEMs/vendors don’t want to give up 24 GHz, change of the administration…) Canada and Brazil follow the FCC China: study triggered in 2017. Target: SRRC /SRTC new regulation Japan: will follow outcome under AI 1.18 of WRC-15 Note that implementation of WRC-15 results may take about 2 years.
Sensors > 95 GHz A considerable part of the spectrum above 100 GHz shows entries for passive services. FCC action noted - Opening 95-475 GHz to Commercial Use – FCC 14-177 A potential demand is seen for sensor applications, also within the automotive field. New ETSI proposal (Srdoc) for UWB radiodetermination applications within the frequency range 120GHz to 260GHz in preparation (will it include automotive?) There are no existing military applications above 100 GHz The allocation status is identical for all three ITU-R regions. Fixed Service channelisation arrangements in preparation for 92-114.5 GHz and 130-174.8 GHz bands in CEPT A promising frequency option could be 136-141 GHz (with radiolocation, amateur and RAS allocations) while there is also a radiolocation allocation up to 148.5 GHz (above 141 GHz, also FS and MS allocations) It’s the right time to report/set out demand NOW
3GPP V2V/V2X 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 237 (WRC-15); CEPT received so far no direct contribution on 3GPP V2V/V2X 5.9 GHz: all existing studies based on IEEE 802.11/11p/ ETSI G5 The press release from 3GPP confirms that the two intended communication configurations (with or without base stations) use a dedicated carrier for V2V communications, meaning the target band is only used for these V2V communications ACEA (European car manufacturers association) on the topic of spectrum redundancy for ITS and coexistence between ITS-G5 and LTE-V2X. Expresses the concept of spectrum redundancy to maintain the exclusivity of 5.9 GHz to ITS-G5 while offering an opportunity in 3.4-3.8 to LTE-V2X CEPT received from the European Commission a 5G mandate incl. 3.4-3.8 GHz
Policy Opinion (ITS G5 vs 3GPP) No immediate need to take any regulatory action Many stakeholders raised concerns that competing technologies in 5875-5905 MHz could impact on interoperability and utility of this band. Regulation: it is important to be technology neutral. Considering which technology is most suitable for safety-related ITS is not a spectrum policy matter. However, if the current debate over coexistence of technologies in this spectrum band is not resolved, it may be appropriate to consider if any action is needed – for example by referring the matter to the relevant European standardization body.
Other activities (automotive field) CEPT studying amendments of the UWB regulations for vehicular access systems and also additional alternative mitigations to be used in vehicular use cases -> new options Wireless Power Transmission (WPT): for electrical cars Compatibility studies Target: relaxation of limits for inductive applications (e.g. in 79-90 kHz)
