Public Consultation 23-02-2024
Permanent Work Item False
Comments In ECC/DEC/(20)01, the -45 dBm/MHz OOB limit below 5935 MHz for VLP would allow VLP initial market to take up. CEPT agreed that this OOB limit should be valid in time only until 31 December 2024 and be re-examined with regard to an opportunity to relax it based on the real IEEE and DSSS Urban Rail interference situation. In absence of the justified evidence, a value of -37 dBm/MHz, for the OOB limit below 5935 MHz, will be adopted from 01/01/2025.


Text added by WGFM #99 meeting 24 to 28 May 2021.
Possible alignment of ECC/DEC/(20)01 with ECC/DEC/(04)08 with respect to the “non-protected and non-interference basis” provision may be considered.
