Clause 16 devices have the capability of bringing 2.4GHz networks to their knees. 13/0416 (latest is r5 at time of writing comment) shows that there is no technical reason to maintain Clause 16 devices. It is suggested that a note be added to this Clause to indicate that it is now 'out of favor' and that it is likely to be dropped in the (near) future. Add text under heading "Devices supporting the DSSS system are no longer encouraged and likely to be deprecated from this Specification in subsequent revisions" 2412 1974.01 17 As noted in CID 32,"11b is Poison". Clause 17 devices are coupled to Clause 16 DSSS and as such have the capability of bringing 2.4GHz networks to their knees. 13/0416 (latest is r5 at time of writing comment) shows that there is no technical reason to maintain Clause 16 or 17 devices. It is suggested that a note be added to this Clause to indicate that it is now 'out of favor' and that it is likely to be dropped in the (near) future. Add text under heading "Devices supporting the high rate extention to the DSSS system are no longer encouraged and likely to be deprecated from this Specification in subsequent revisions" CIDs 2423, 2424 – ERP PHY CIDs 2411, 2412 – DSSS deprecation Dorothy Stanley, Aruba Networks Dorothy Stanley, Aruba Networks
Withdrawn by Commenter Withdrawn by Commenter July 2010 doc.: IEEE 802.11-11/0291r0 May 2014 TGmc – Wednesday PM2 2423 2048.25 9.1.2 The standard requires 11n and 11g (i.e., HT and ERP) PHYs to support transmit and receive of all 11b modes. Given the enormous disparity in efficiency between 11b and the OFDM modes, this no longer makes sense as a universal requirement for all products, and any such requirements should be removed, if not necessary to support coexistence. A straightforward way of accomplishing at least some of this is to remove the requirement that ERP PHYs support the 5.5 and 11 Mbps CCK data rates. Since Clause 20 (HT) references Clause 19 (ERP), this would remove 5.5 and 11 Mbps as requirements for HT also. This would not affect the requirment to be able to detect the long or short preamble (1 Mbps and 2 Mbps) and to take appropriate action based on such a detection, thus preserving the current level of coexistence. Delete 5.5 and 11 from list of mandatory data rates for ERP PHY. Also make corresponding changes throughout, including section 9.1.3 (P2048 LL30-37) (add 5.5 and 11 to list of exceptions); section 19.3.5 (P2054 LL39-40) (delete 5.5 and 11 from list); and Annex B.4.9 (P2307 LL33-37) (remove 5.5 and 11; add new entry ERP1a for 5.5 and 11, optional) 2424 2048.37 9.1.3 The standard requires 11n and 11g (i.e., HT and ERP) PHYs to support transmit and receive of the 11b Short Preamble. This is optional for 11b. This requirement no longer makes sense (if it ever did), as there are legacy deployed devices that do not recognize the short preamble or defer for it, and it seems that most deployed devices do not transmit the short preamble. Remove the sentence beginning "In addition, it is mandatory ...". Also make corresponding changes throughout, including section 19.3.2.1 (P2052 LL32-41) (change "three" to "two" and delete short preamble from list; add extra line saying that an ERP STA may support the short preamble); section 19.3.2.3 (P2053 L16) (delete sentence begiining "For the ERP..."); section 19.3.5 (P2054 L40) (delete "or short"), and (P2054 L46) (delete "short preamble").

3GPP liaison- Question 1, 2+ July 2010 May 2010 doc.: IEEE 802.11-10/0503r4 doc.: IEEE 802.11-14/0415r0 May 2014 3GPP liaison- Question 1, 2+ Does IEEE 802.11 WG consider WLAN RCPI a suitable metric of WLAN signal strength such that it can be compared to thresholds as in the above described mechanism? We consider the RCPI value as defined in IEEE 802.11™-2012 a suitable metric for signal strength. Could add: However, there may be more suitable metrics or sets of metrics as outlined in the response to question 3. Add 95%. Does IEEE 802.11 WG consider WLAN RSNI a suitable metric of WLAN signal quality such that it can be compared to thresholds as in the above described mechanism? We consider the RSNI value as defined in IEEE 802.11™-2012 a suitable metric for signal quality and can be used as described Include table of additional metrics (11-14-572) New separate document with background and explanatory material, not referenced in letter Slide 14 Dorothy Stanley, Aruba Networks Page 14 Sean Coffey, Realtek Michael Montemurro, Research in Motion
July 2010 May 2010 doc.: IEEE 802.11-10/0503r4 doc.: IEEE 802.11-14/0415r0 May 2014 3GPP liaison- Question 3 Does IEEE 802.11 WG consider any other WLAN signal metric more suitable for the above described mechanism? IEEE Standard 802.11™-2012 defines additional values that you might deem helpful for the envisaged usage scenario. Among them we highlight the channel load and noise histogram that provide channel usage statistics. These statistics can be helpful to identify busy channels complementing RCPI and RSNI measurements. Also Received Signal Strength Indicator (RSSI) measurement methods that mitigate against the effects of short-term channel fading might support the decision making process, however there are no accuracy requirements specified for RSSI. Please note that frequency channel bandwidth, number of spatial streams, and other values also impact QOS and throughput. We consider the use of estimated and/or measured values of WLAN throughput to be more appropriate for the mechanism described. The IEEE Standard 802.11™-2012 defines many metrics suitable for access network selection and traffic routing for the mechanism described in your letter. As detailed below, a technically sound network selection requires using multiple metrics to select the best network for the QOS required by the STA.
