4 Executive summary
ECC Decision (08)01 and Commission Decision 2008/671/EC [i.5] identify the frequency band 5 875 MHz to
5 905 MHz on a non-exclusive basis for ITS road safety applications. ECC Decision (08)01 is currently implemented in
39 CEPT countries including all EU member states. TR 101 607 [i.16] includes the standards developed under the
mandate 453 and was agreed in early 2013 as the Release 1 for ITS in the spectrum 5 875 MHz to 5 905 MHz. The
objectives for a release process are:
• An organized process for standardization activity for cooperative ITS.
• Standardizat
