  1. Sub 1 GHz PAR Further Comments Authors: Date:2010-07-15 David Halasz, Aclara

  2. The following are comments beyond the PAR review Wednesday 5 o’clock timeframe. They are in response to the updated PAR contained in 10/0001r10. Abstract David Halasz, Aclara

  3. Comment 1 from Apurva Mody From: apurva mody [mailto:apurva_mody@yahoo.com] Sent: Wednesday, July 14, 2010 3:08 PM To: Halasz, Dave Subject: Re: [STDS-802-11-S1G] S1G Comments, Responses and proposed new PAR Dear Dave, I sent the comments from PIEEE 802.22 WG through Bruce Kraemer. I believe that you have made some progress on resolving our comments. We still have a problem with the sentence - " This amendment defines operation in license-exempt bands below 1 GHz, excluding the TV White Space. P802.11af defines operation in the TV White Space bands, which are below 1 GHz." The words "TV White Space" should be changed to "TV frequency bands". Thanks Apurva ___________________________________________________________ Apurva N. Mody, Ph. D.

  4. Comment 2 from Lily Yang From: Yang, Lily L [mailto:lily.l.yang@intel.com] Sent: Wednesday, July 14, 2010 6:01 PM To: jrosdahl@ieee.org; Halasz, Dave; Bruce Kraemer Subject: FW: [802.15.4g] Fwd: 802.11 S1G PAR coment response and Revised PAR and 5C Dave/Jon/Bruce – Sorry that I didn’t make it to the morning S1G meeting so didn’t get a chance to give you this feedback. The first sentence – “This amendment defines enhancements to the IEEE 802.11 Medium Access Control (MAC) to support an Orthogonal Frequency Division Multiplexing (OFDM) Physical layer (PHY) operating in the license-exempt bands…” seems to imply that the amendment only defines MAC changes, which I thought is just the opposite of what you meant to say. S1G defines OFDM PHY for a new band with minimum MAC changes to support the rebanding. I hope this is just my misunderstanding but I want to mention to you to avoid mis-interpretation down the road that may create problem. I did vote for the motion in the mid plenary this morning based on the understanding I got from last night’s meeting, not based on my interpretation of this sentence which I think is not intended.

  5. Comment 3 from 802.15 TG4G -----Original Message-----From: Phil Beecher [mailto:pebeecher@gmail.com] On Behalf Of Phil BeecherSent: Thursday, July 15, 2010 2:14 PMTo: Bruce Kraemer; Halasz, DaveCc: James Gilb; Bob HeileSubject: Fwd: 802.11 S1G (SubGHz) PAR and 5C discussion Dear Bruce, Please circulate as appropriate: 802.15 TG4g discussed the revised 802.11 SubGHz PAR and 5C, and comment responses. The following comments were unanimously agreed by TG4g (For:30, Against:0, Abstain:5) * The PAR does not offer any uniqueness or advantages as compared to 802.15 TG4g draft standards activity on PHYs to meet the subGHz requirement. TG4g has PHYs that work in these frequency bands which should be considered. Data rates should be consistent with existing 802.11 data rates. Below 1.2Mbps it is recommended that 802.15 TG4g PHY's be used * If this PAR is accepted as proposed, it is not justified to restrict the acceptable PHY modes to OFDM only. Other PHY modes currently under consideration in TG4g also meet the 802.11 S1G PAR requirement. * The statement "while coexisting with the 802 PHYs currently operating in the respective band. " is not strong enough. TG4g recommends using the wording adopted in 802.15.4g PAR and 802.11ad PAR. Regards, Phil Beecher Chair 802.15 TG4g David Halasz, Aclara
