It seems that United Nations standard for every home network in the world, also know as, ITU G.hn, will have an additional update to (Amendment to G.9960) to address the regulatory/emission shortcomings of G.hn.
HAN Fan has been told that there is a huge (by huge she means enormous) fight within the ITU. On one side, the ITU-T (e.g. big entrenched telcos) who have pushed G.hn without regard any possible interference to licensed radio users. On the other side is the ITU-R, the masters of the usage of radio broadcast. Boom.
HAN Fan recalls the saying, "haste makes waste".
Depending on the path to sort this out: whether it is AAP ( Alternate Approval Process) or TAP ( Traditional Approval Process), it could take few months to couple of years before the G.hn is finalised..
