FCC Publishes KDB 511808 D01 C-V2X v02

On February 24th, the FCC published KDB 511808 D01 C-V2X v02 to replace KDB 511808 D01 C-V2X Waiver v01r01 to provide clear guidance for manufacturers seeking equipment authorization for C-V2X devices operating under Part 90M (for RSUs) and Part 95L (for OBUs) rules, in light of the recent release of the Second Report and Order.

The main points are as follows:

  • Equipment Classes
    • Roadside Unit (RSU): CVR
    • On-board Unit (OBU) without geofencing: CVO
    • OBU with geofencing: CVG
  • Devices certified under the previous waiver order are grandfathered, and no additional action is required as long as no changes are made.
  • Technical Requirements refers to Part 90M and Part 95L rules, including specific testing procedures for:
    • Occupied bandwidth (26 dB and 99% power bandwidth)
    • Transmit power (RMS EIRP)
      • May be calculated from conducted power measurements only if the antenna data have sufficient resolution to determine the antenna gain within ±5 degrees from the horizontal plane.
      • OBUs with a max EIRP > 27 dBm shall describe the mechanism for reducing the main beam power to 27 dBm when the beam is within ± 5 degrees from the horizontal plane.
    • Out-of-band emissions (OOBE)
  • Geofencing Requirements
    • The geofencing mechanism may be an integrated or a separate GNSS system source that uses a full-time connection and can only be received from US-licensed or approved satellites.
    • The expected meter accuracy for one standard deviation or Circular Error Probability (CEP) must be specified.
    • The maximum default EIRP must be specified when the OBU cannot retrieve an accurate location fix, which is the same as an OBU without geofencing.
    • The OBU must reduce power upon entering a coordination zone. This can be verified by creating a local test coordination zone and radius on the OBU to demonstrate how the OBU lowers its power when entering the test location. The test report must include the time between high and low power versus entry time and power adjustment, and must also list the test coordination zone, the radius used for testing, and the speed at which the device traveled when entering the coordination zone.
    • If coordination zones and parameters are subsequently modified or added, a mechanism to update OBUs with the new information shall be provided. All geofenced OBUs shall have internet access to a manufacturer's push service to update coordination zones and parameters if necessary, according to 47 CFR §90.387(b).

ISED Issues Guidelines for Module Certification Under RSS-248

ISED has issued the following guidelines to clarify some of the requirements applicable to module certification when subject to RSS-248 compliance:

  • Any module certified or to be certified under RSS-248 is automatically considered as Limited Modular Approval (LMA) as per section 4.8.7 of RSS-248 issue 3.
    • Full Modular Approval (MA) is not permitted under any classes for modules subject to RSS-248.
    • Modules can be treated as LMA under all classes in RSS-248, except for indoor subordinate devices, which cannot be certified as modules under any circumstances (neither MA nor LMA).
  • Even if a module meets all the requirements of RSP-100 Form D (which allows MA), the requirements in RSS-248 takes precedent and restrict the ability to proceed as MA. Instead, the module is automatically considered for LMA (except for indoor subordinate devices that cannot be certified as modules).
  • It is not required to submit applications to ISED for the sole purpose of changing the status of previously certified modules from MA to LMA. ISED intends to modify the MA status for previously certified modules to LMA directly in Spectra.
  • ISED does not require C4PC applications for certified modules that are already integrated into hosts which were introduced on the market prior to RSS-248 issue 3. Module and host manufacturers are nevertheless responsible for assessing that the hosts currently on the market, which contain RSS-248 modules, meet all the requirements associated with the designated class in RSS-248 issue 3.
  • For any RSS-248 modules that are newly integrated into hosts (not yet on the market), ISED requires C4PC applications to demonstrate that the hosts do comply with the specific requirements of the applicable class in RSS-248 issue 3.
  • ISED allows a C4PC application for a module (which meets all the MA requirements) to cover a specific class in RSS-248 (as an alternative to cover a single host), as long as the CB certificate includes certification conditions that clearly indicate that the module can only be installed into hosts of a specific class:
    • The certificate conditions shall also list the specific requirements associated with the RSS-248 class and indicate that installation instructions shall be included with the module to ensure that the module is only installed in the designated class of hosts.
    • If a module needs to be integrated into a second class of hosts, another C4PC application will be required to cover this second class of hosts.

ISED notes that the submission of a C4PC application for a module to cover multiple hosts sharing the same class under RSS-248 will not be possible if RF exposure compliance needs to be assessed separately for each combination of module/host. In such a case, a C4PC application will be required for each module/host combination.

Additional Q&As:

  • Q1. If a 6GHz module meets all MA conditions, will any additional testing be required for subsequent integrations in new hosts that do not affect the original certification conditions?
  • A1. No additional testing is required for the C4PC. The final product shall meet the limits and conditions of the equipment class of the host.
  • Q2. In such cases, would multiple Host Marketing Names (HMNs) be permitted under a single C4PC application for variant hosts?
  • A2. Yes, as long as all the hosts fall under the same equipment class as defined in RSS-248.

UK Issues Guidance on Use of UKCA and CE Markings on Products Entering Great Britain

On February 3, the UK Department for Business and Trade issued new guidance to allow businesses to have the flexibility to use either the UKCA or CE marking to place relevant products on the Great Britain (England, Scotland, and Wales) market:

  • Manufacturers may use the UKCA marking for products that have met either the UK or recognized EU essential requirements and conformity assessment procedures.
  • A product may be affixed with the UKCA marking if it demonstrates UK requirement compliance by a combination of both UK and recognized EU conformity assessment procedures.
