NOTE FROM TC/SC OFFICERS:
This CDV implements decision 3 of the CIS/B meeting in San Francisco where it was decided to
continue the project CISPR 11 (after the failed B/802/FDIS) with a CDV which contains the technical
aspects of the fragments f2, f4, f5, f6 and f7.

1 INTRODUCTION TO THIS CDV
2 Note: the text of this INTRODUCTION will not be part of a final publication of the next edition
3 of CISPR 11.
4 The maintenance activities related to CISPR 11 Ed. 6.2 started in 2016 with the document
5 B/662/DC and the outcome given in B/670/INF. The latest document on those maintenance
6 activities was B/802/FDIS, which however failed the vote.
7 The further progress with respect to that project was discussed at the CISPR/B meeting in
8 San Francisco in 2022 (see B/813/RM). There it was decided, see decision3 of B/811/DL to
9 continue with the project in that way that contents related to the topic of WPT will be removed
10 from the current project and will be separately treated in future amendments or editions. The
11 other fragments, i.e. f2, f4, f5, f6, and f7, will be merged together in this CDV which contains:
12 • f2: general maintenance issues, as for example revision of definitions and annexes
13 (following B/739/CD, B/757/CC, B/761/CD, B/772/CC, B/777/CDV and B/794/RVC)
14 • f4: requirements when performing emission measurements on robots (following
15 B/741/CD, B/751/CC, B/754/CD, B/768/CC, B/779/CDV and B/798/RVC)
16 • f5: requirements for wired network ports (following B/742/CD, B/753/CC, B/758/CD,
17 B/771/CC, B/780/CDV and B/797/RVC)
18 • f6: requirements for Group 1 equipment in the frequency range above 1 GHz (following
19 B/743/CD, B/755/CC, B/759/CD, B/769/CC, B/781/CDV and B/795/RVC)
20 • f7: requirements for radio enabled products (following B/744/CD, B/756/CC, B/760/CD,
21 B/770/CC, B/782/CDV and B/796/RVC)
22 The work on the fragments f1 (WPT EV) and f3 (Radio beam WPT) will be subject to different
23 documents and continued after circulation of this CDV.
