Dear Tatsuta-san
Thank you for the slides describing IEEE and ITU_T terminology.
Regarding the ITU-T terminology, I have attached a re-drawn version of the slide which, I think, represents the meaning of the terminology used in ITU-T

Dear Robert and Marek,
Thank you for your arrangement.
I have some opinions about this issue.
I think our target is 29dB maximum insertion loss so far (See a result of the straw poll in November meeting, which is described in page 6 and 8 of http://www.ieee802.org/3/av/public/2006_11/3av_0611_closing.pdf).
So, at first, we need to decide the power budget, and it is derived from the spread sheet which Marek is making now.
I made a slide which described a relation between some numbers, which were defined in Tanaka-san presentation in November, and the spread sheet.
Also, I made a slide which described ITU-T terminology for your information.
Can we start to define the power budget?
Sincerely yours,
Tsutomu TATSUTA
