Here are my comments on the proposed patch... country IL: > > (2402 - 2482 @ 40), (N/A, 20) > > + (5150 - 5250 @ 40). (N/A, 200 mW), NO-OUTDOOR > > + (5250 - 5350 @ 40). (N/A, 200 mW), NO-OUTDOOR, DFS a) I agree with channels above and enabling HT40 per above. b) I think all entries in the dbase should be in dBm (not mW). dBm vs. mW are absolutely equivalent. No reason to retain "mW" unit from the source docs. I think this was agreed by all before, but wanted to reiterate. c) I don't understand why "Indoor/Outdoor" is stated in the table for any/all countries. 5150-5250 is globally allocated for indoor use. So I am not reviewing/commenting on the indoor/outdoor comments in the dbase. d) Reminder...Israel and most other countries state max tx power limit in 'EIRP' (ie takes into account actual antenna gain of the end device). Therefore, the entire dbase must be clearly flagged so developers know the tx power limits in this dbase only apply when devices have 0dB (or negative) gain antennas. In other words, the software (or the hw/sw developer) must somehow reduce tx powers below the values in the dbase, dB-for-dB, when antenna+cable has positive gain. The exception is FCC target power, where FCC (and the dBase) quotes "conducted power" rather than EIRP. Issue d) is not a concern for manufacturers/developers who produce products that limit regulatory tx powers in the hw (factory set/limited). In that case they take into account actual antenna gains during original conformance testing and program in compliant tx powers into hw (and don't rely at all on the tx powers in the dbase). But developers who don't have tx powers limited in hw, who actually use the tx power in the dbase, must take into account antenna gain as explained above, else the product may not comply with tx limits for most countries. Fine if you want to discuss point d) separately since it's a global issue (not limited to this particular IL patch). tks, Michael Green Atheros Communications, Inc. mgreen@xxxxxxxxxxx Desk: +1-781-400-1491 Mobile: +1-508-380-4921 -----Original Message----- From: Emmanuel Grumbach [mailto:egrumbach@xxxxxxxxx] Sent: Sunday, June 20, 2010 1:41 AM To: John W.

Yes, I think that Michael Green agreed for this patch. Once he will reply to make sure, we will be able to move on to a real patch. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
