C-V2X - RSS-252 issue 2 consultation - Intelligent Transportation Systems

ISED Canada seeking comments on the consultation of RSS-252 issue 2, Draft 1, May 2023 regarding ‘Intelligent Transportation Systems’ (ITS) On-Board Units (OBUs) in the 5895 – 5925 MHz Band’

The standard sets out requirements for equipment certification of license-exempt Cellular Vehicle-to-Everything (C-V2X) radio equipment within the 5895 to 5925 MHz frequency band.

RSS-252 Issue 2 constitutes a completely re-written standard replacing the entirety of RSS-252 Issue 1. Issue 1 of the standard, deprecated as of April 1, 2023, at which time ISED would no longer accept applications for certification under RSS-252 until a new issue is published, effectively rescinding ITS designation in the 5850 to 5895 MHz band.

Highlights;

• RSS-Gen compliance required
• References 3GPP Specification 21.914, Release 14 (or newer releases containing C-V2X)
• Average e.i.r.p. for C-V2X OBU shall not exceed 2W (33dBm)
• Unwanted emissions -29,-35,-43,-53 dBm/100 kHz @ band edge +1,+10,+20, >20 MHz
  
• Applicable measurement standard is ANSI C63.26  

RSS-252, Issue 2 will be in force as of the date of its publication on Canada's ISED website.

Comments are due no later than July 28, 2023
