Re: [10GBT] Transmit power levels

Dear Mr. Zimmerman,

 

Earlier this week, u made couple of comments regarding transmit power levels in reply to Sanjay's email on this reflector (in blue fonts):

 

(1) No , at the time of Joseph's presentation we noted it was  not correct.  I can't answer  in  detail now (I'm on my mobile ), but we will at the meeting or before.

- we appreciate ur effort in replying even thru ur mobile. i hope u r not on ur mobile 24x7, and will kindly explain ur comment soon on this forum. Just let us know where we r wrong.

 

Also, in response to Joseph's email regarding Mr. Bill Jones's email explaining peak-to-peak voltage for solarflare tutorial, this is what u replied:

 

(2) As mentioned several times, please don't Confuse the tutorial wlth a proposal.

- well, why dont u just clarify Solarflare's position on "actual peak-to-peak voltage" and transmit power levels and let everyone know where u guys stand, for once and all?

 

- we will sincerely appreciate ur response before the meeting.

 

thanks,

Samir.

    Subject: [10GBT] Transmit power levels
      A quick scan through past presentations reveals a few different
    proposals for transmit power levels.

    http://www.ieee802.org/3/10GBT/public/mar03/babanezhad_1_0303.pdf , a
    March 2003 presentation by Joseph Babanezhad of Plato Labs, proposes 2v
    peak to peak and also has a table on slide 16 that lists other prior
    proposals: 2v peak to peak from a proposal from Cicada and 3.134v peak
    to peak for a proposal from Solarflare.

    A subsequent presentation from George Zimmerman of Solarflare,  gives a
    range of  TX power, > 6dBm to <10dBm though there is no mention of
    actual peak to peak voltages. If I assume that the 3.134v peak to peak
    corresponds to 10dBm then the 6dBm number will be about 2v peak to peak.

    Joseph, Vivek (Cicada) and George - is my interpretation of each of your
    proposals correct? Were there any other proposals on transmit power?

    Thanks,
