FCC 24-123 Use of the 5.850–5.925 GHz Band — Second Report and Order
Published finalMandatorySpectrum
The order that made C-V2X the only permitted technology in the US 5.9 GHz ITS band and set the end of DSRC. Three 10 MHz channels at 5895–5925 MHz, combinable to 20 or 30 MHz. It is a radio rule: it authorises transmission, it does not require any vehicle to carry a radio and it mandates no 3GPP release.
Relevance to 5.9 GHz LTE C-V2X PC5 Directly relevant. It is the instrument under which a 5.9 GHz PC5 device may be operated in the United States, and it fixes the band edges and emission limits a US-market design has to meet.

Adopted 20 November 2024, released 21 November 2024, read from the order itself. The order sets the DSRC sunset as two years from Federal Register publication and carries date placeholders, so the operative dates were read from the codified rule: 47 CFR 90.350(a) states that DSRCS stations must cease operations in 5895–5925 MHz no later than 14 December 2026 and that no new DSRCS licences issue after 11 February 2025. Federal Register publication was 13 December 2024 (document 2024-28980), with a correction published 17 January 2025 (2025-00642).

Read from IFT's own communication. It approved putting a questionnaire out to public consultation for twenty working days, 20 August to 17 September 2021. It is an information-gathering step and carries no binding effect: it allocates nothing, authorises nothing and decides nothing. No later Mexican instrument was traced through the current register or the Diario Oficial in this pass, and none should be inferred either way.

Decision (EU) 2020/1426 Commission Implementing Decision (EU) 2020/1426 on the harmonised use of radio spectrum in the 5 875-5 935 MHz frequency band for safety-related applications of intelligent transport systems (ITS) and repealing Decision 2008/671/EC
Published finalMandatorySpectrum
The parent EU spectrum instrument. It harmonises 5875–5935 MHz across the Union for safety-related ITS and splits it between road and urban rail. Road ITS gets 5875–5925 MHz, not the whole 60 MHz, and the top 10 MHz is urban rail only.
Relevance to 5.9 GHz LTE C-V2X PC5 Sets the band a European PC5 device operates in and the priority rules it shares the band under. It is technology-neutral: it permits PC5 and ITS-G5 alike and endorses neither.

Adopted 7 October 2020, notified as C(2020) 6773, published OJ L 328/19 on 9 October 2020. Operative articles read in full. Article 3(1): Member States were to designate 5875–5935 MHz for ITS by 30 June 2021 and to limit 5925–5935 MHz to urban rail ITS. Article 3(2): road ITS has priority below 5915 MHz, urban rail ITS above it. Article 3(3): access by road ITS to 5915–5925 MHz is limited to infrastructure-to-vehicle connectivity only. Article 3(4): urban rail access to 5925–5935 MHz is shared and subject to national circumstances. Its Annex was replaced in full by Decision (EU) 2026/1800.

Decision (EU) 2026/1800 Commission Implementing Decision (EU) 2026/1800 amending Implementing Decision (EU) 2020/1426 as regards introducing wider frequency channels in the Union-harmonised 5,9 GHz frequency band for safety-related applications of road intelligent transport systems
Published finalMandatorySpectrum
The amendment that allows 20 MHz channels in the European 5.9 GHz road ITS band, by combining two adjacent 10 MHz blocks. It comes with one limitation that matters: the 20 MHz channel at 5905–5925 MHz may be used for infrastructure-to-vehicle communications only, because its upper half overlaps the 5915–5925 MHz range where road ITS has been restricted to I2V since 2020 to protect urban rail. This is not a ban on 20 MHz channels generally, and it is not a restriction on the 10 MHz channels.
Relevance to 5.9 GHz LTE C-V2X PC5 Directly relevant to European PC5 channel planning. A 20 MHz PC5 carrier is now permitted in the band, but a design that assumes vehicle-to-vehicle transmission on a 20 MHz channel at 5905–5925 MHz is planning against a channel the Decision does not permit it on.

Adopted 24 July 2026, notified as C(2026) 5125, published in the OJ L series on 28 July 2026. Article 1 replaces the Annex to Decision (EU) 2020/1426 in full; the operative Annex was read before this record was written. The frequency-arrangement row states: "Two blocks may be combined in one contiguous 20 MHz channel" and then "Use of the 20 MHz channel formed by two blocks of 10 MHz within the frequency band 5 905-5 925 MHz shall be limited to infrastructure-to-vehicle communications, noting that restrictions apply to the frequency band 5 915-5 925 MHz in accordance with Article 3(3)." Recital 6 gives the reason: the limitation stands pending the availability of solutions ensuring protection of urban rail ITS in 5915–5925 MHz, following CEPT Report 91 adopted 7 November 2025. The new Annex also adds an unwanted-emissions limit above 5925 MHz of -30 dBm/MHz EIRP for road ITS and restates TPC as a requirement to reduce total power from its maximum to 3 dBm EIRP, where the 2020 Annex specified a TPC range of at least 30 dB. The Decision carries no separate Member State application deadline.

The live Ofcom document was read on 29 September 2026 and is Version 2.0, publication date March 2023 — the same edition SI 2023/243 names, and the current one. Table 3.1: frequency band 5875 to 5925 MHz; maximum mean transmit power 23 e.i.r.p. dBm/MHz; maximum total transmit power 33 dBm mean e.i.r.p. with a TPC range of at least 30 dB; channel access and occupation rules requiring interference mitigation at least equivalent to ETSI EN 302 571; authorisation regime licence exempt; references EN 302 571 and EN 302 665; Northern Ireland notification number 2022/7004/XI. Channelling is recorded as "N/A" — Ofcom specifies no channel plan. Source conflict, unresolved: the document history table describes Version 2.0 as "Amended to include 5805-5825 MHz", but 5805–5825 MHz appears nowhere in Table 3.1 or elsewhere in the document, and SI 2023/243 exempts only 5875–5925 MHz. Ofcom has not been asked to reconcile this and the site does not guess at which is intended.

Allgemeinzuteilung von Frequenzen für sicherheitsbezogene Funkanwendungen intelligenter Verkehrssysteme (Intelligent Transport Systems, ITS) im Frequenzbereich 5875 – 5915 MHz
Published finalMandatorySpectrum
Germany's national implementation, and a caution against reading the EU band as a national permission. Germany assigns 5875–5915 MHz generally — 40 MHz, not the EU's 50 MHz of road ITS spectrum and not 60 MHz — everything above 5915 MHz needs an individual assignment, and the assignment itself runs out at the end of 2026.
Relevance to 5.9 GHz LTE C-V2X PC5 A PC5 deployment in Germany is planned against 5875–5915 MHz in 10 MHz blocks, not against the EU-wide range and not, on this assignment, against a 20 MHz channel.

Consolidated PDF read in full; the Bundesnetzagentur general-assignment index still listed this as the current ITS assignment at its 15 April 2026 revision. Issued under § 55 TKG and stated to be a partial implementation of Decision (EU) 2020/1426 in Germany. Parameters: 23 dBm/MHz maximum spectral EIRP density (200 mW/MHz) and 33 dBm maximum EIRP (2 W), with TPC over a range of at least 30 dB. Road ITS takes priority over urban rail ITS. Frequency arrangement: 10 MHz blocks from 5875 MHz, channels within block boundaries, bandwidth may be lower than 10 MHz — no provision for combining blocks into a 20 MHz channel. Two conditions are easy to miss and are the reason this record exists: the assignment is time-limited and expires on 31 December 2026, and for 5915–5935 MHz every ITS radio application must apply to the Bundesnetzagentur for an individual frequency assignment.

India's licence exemption for 5.9 GHz on-board units — and only for on-board units, and only across the lower 30 MHz. It removes the spectrum licence. It does not remove equipment type approval, which rule 4(3) requires for each equipment type through the DoT portal.
Relevance to 5.9 GHz LTE C-V2X PC5 The instrument that makes a PC5 on-board unit operable in India without a spectrum licence, and the source of the power limits an Indian-market design is held to.

Gazette text read in full. Notification dated 10 June 2026, published in the Gazette of India Extraordinary Part II Section 3 Sub-section (i), No. 416, on 11 June 2026, made under sections 4 and 7 of the Indian Telegraph Act 1885 and sections 4 and 10 of the Indian Wireless Telegraphy Act 1933, in force on the date of publication. Rule 2: "They shall apply in respect of the 5875-5905 MHz frequency band." Rule 3(1)(e) defines an On Board Unit as radio equipment including its antenna operated as part of an intelligent transport system established for road transport that is installed on a vehicle, forms part of a vehicle, or is held or carried by an individual in relation to a vehicle — the third limb is easily missed. Rule 4(1) permits establishment, maintenance or working of such a unit for the sole purpose of cellular vehicle-to-everything communication without assignment of radio frequency, on a non-interference, non-protection and non-exclusive basis, and requires no licence for possession, sale or hire. The table gives 23 dBm/MHz maximum power spectral density EIRP and 33 dBm maximum EIRP for in-band emissions and -30 dBm/MHz for out-of-band emissions. Rule 4(3) requires permission and exemption to be sought for each equipment type through an application on the Department of Telecommunications portal, unless that equipment type is already approved and published there. Rule 4(4) requires conformity with standards notified by the Bureau of Indian Standards or the Central Government, and relevant international standards where none has been published. Roadside units are not within these rules and 5905–5925 MHz is not opened to on-board units by them.

Draft AIS-230 Draft AIS-230 — C-V2X on-board unit requirements for factory-installed systems
Draft or consultationBinding effect unknownVehicle fitment
India's proposed standard for factory-fitted C-V2X on-board units, and the thing a proposed 2028 fitment requirement would be written around. It is a draft. Nothing in it is required of anyone.
Relevance to 5.9 GHz LTE C-V2X PC5 Potentially the largest single PC5 fitment requirement anywhere, if it is finalised. Until a final notification exists it constrains nothing, and no product can conform to a standard whose text is not published.

AIS-230 is a draft and is not in force. The text of the standard is not publicly accessible, so everything recorded about its contents comes from MoRTH's own description of it rather than from the document. The draft amendment to the Central Motor Vehicles Rules that would give it effect was published on 3 August 2026 for thirty days' comment; no final notification had been published in any accessible public source as of this verification pass. MoRTH quotes 5875–5925 MHz for the standard, which is wider than the range G.S.R. 466(E) actually exempts.

F2018L00026 (compilation F2021C01285) Radiocommunications (Intelligent Transport Systems) Class Licence 2017
Published finalMandatorySpectrum
The lightest-touch authorisation among the major markets: no application, no fee, one band, one power limit and one referenced European standard. "ITS station" covers vehicle and roadside alike.
Relevance to 5.9 GHz LTE C-V2X PC5 Relevant to Australian operation. Note what it does and does not say: it conditions operation on compliance with EN 302 571 and does not itself permit or forbid PC5 or ITS-G5 by name, so which technologies are allowed follows from that standard rather than from the licence.

Verification note — Publisher’s own text read
Compilation text read in full; the latest compilation is F2021C01285, compilation C02, dated 17 November 2021. Section 6(1) authorises a person to operate an ITS station subject to four conditions: it must be operated "on a frequency, or within a range of frequencies, greater than 5855 MHz and not greater than 5925 MHz" and "at a radiated power that does not exceed a maximum EIRP of 23 dBm/MHz"; it must not be operated within 70 kilometres of the Murchison Radioastronomy Observatory; it must comply with ETSI Standard EN 302 571; and it must comply with section 7. Section 6(2) makes the frequency and power conditions prevail over EN 302 571 in the event of inconsistency, and section 7 requires compliance with any applicable ACMA equipment rules. ACMA confirms no application and no fee. The instrument names no technology, sets no total-power limit beyond the per-megahertz figure, and draws no distinction between vehicle and roadside stations.

IMDA TS DSRC Technical Specification for Dedicated Short-Range Communications (DSRC) in Intelligent Transport Systems (ITS)
Published finalBinding effect unknownRadio and access
A primary Singapore source does exist, and this is it. It is a DSRC specification, built on IEEE 802.11 and IEEE 1609, and it allocates 5855–5925 MHz for DSRC operation in Singapore.
Relevance to 5.9 GHz LTE C-V2X PC5 None, and this is the point of the record. The document is DSRC and mentions no cellular V2X technology. Nothing in it authorises PC5 operation in Singapore, and no Singaporean PC5 position should be inferred from it in either direction.

Document read in full. Issue 1 Revision 1, October 2017, prepared by the Telecommunications Standards Advisory Committee working group on ITS-DSRC. Clause 1.1 bases it on IEEE 802.11 with PHY and MAC modifications, DSRC in the 5 GHz spectrum, and IEEE 1609 WAVE. Clause 5.4.1: "The 5.9 GHz frequency spectrum from 5.855 GHz to 5.925 GHz has been allocated for operation of DSRC in Singapore", divided into seven 10 MHz channels. It covers both on-board units and roadside units, with antenna-height conditions on RSUs above 8 m and up to 15 m, and restricts Power Class D devices and RSUs to public safety uses. The words C-V2X, LTE-V2X and PC5 do not appear anywhere in the document. Binding effect is recorded as unknown deliberately: the specification's preface is a placeholder and the document itself states no registration or type-approval obligation, so whether compliance is a condition of equipment registration in Singapore was not established in this pass.

TCROS 2024 Taiwan C-ITS Roadside Open Standards (TCROS) 2024
臺灣協同智慧運輸車聯網路側設施資通訊開放標準
Published finalVoluntaryMessages
Taiwan's open roadside profile: what a signal controller and a roadside unit say to each other, across ten message types. An industry standard, published free, adopted voluntarily.
Relevance to 5.9 GHz LTE C-V2X PC5 It is an application and message-profile standard and says nothing about spectrum or radio authorisation. Taiwan's 5.9 GHz position is a separate question this pass did not resolve — see the open questions on the catalogue page.

Publisher announcement read on 29 September 2026. TCROS is published by the Taiwan Intelligent Transportation Industry Association, an industry association and not a government regulator, on 16 April 2024, as a freely downloadable open standard. It covers ten message and protocol items — SPaT, V2X MAP, SRM, SSM, TIM, PSM, BSM, RSA, EVA and the TCROS use profile — and specifies communication between signal controllers and roadside infrastructure. It was developed with government participation, which is not the same thing as being issued by government. This catalogue does not present it as a binding national radio regulation, because it is not one and no source consulted here says it is.

New Zealand's published ITS guidance, and a good example of why a catalogue records the instrument rather than the impression. It describes 5.9 GHz as potentially suitable and decides nothing.
Relevance to 5.9 GHz LTE C-V2X PC5 None established. No New Zealand authorisation for 5.9 GHz PC5 follows from this page, and none is claimed here.

Read on 29 September 2026 and demonstrably stale: the page still looks forward to "the next World Radio Conference in 2019" and promises an update afterwards, carries no last-updated date, discusses DSRC and C-ITS but not C-V2X or ITS-G5, and states no authorisation type and no allocation decision. It is recorded as historical guidance for that reason. This does not mean New Zealand has no ITS spectrum position — only that no current one was established from this source, and a newer gazette notice or spectrum plan should be sought before anyone relies on it.
