Different interpretations / options out of ETSI TG SRR on the OOB issue ERC REC 74-01 for 76-77 GHz are:
- Option 2.1 seems the correct one, the group has problems, because of the “wanted” limit in option 2.1 for the complete range 76 to 77GHz.
- Option 2.3 would be the next logic step, some industry supports option 2.2 --> simplest one.
- There exists as well option 2.4.
