2. doc.: IEEE 802.11-11/0810r0 Submission Abstract This submission is for selection of key requirement elements for baseline FR-EM (Functional Requirements and Evaluation Methodology) document. Slide 2Minho Cheong, ETRI May 2011

3. doc.: IEEE 802.11-11/0810r0 Submission Background As described in 11/0747r2, key requirements needs to be selected by straw polls in the task group to make an initial draft of the FR- EM document. Plan to have straw polls on the potential key requirement elements after all the presentations during this week are done. Straw polls on approach for evaluation methodology is also to be done. This purpose is for preparation to make an baseline FR-EM document. With the use of these straw poll results, I will try to make an initial version of “TGah Functional Requirements and Evaluation Methodology (FR-EM) document” until the upcoming conference call after Palm Springs meeting. April 2011 Minho Cheong, ETRISlide 3

4. doc.: IEEE 802.11-11/0810r0 Submission Background (2) Meaningful threshold by which key functional requirement elements can be chosen is 75% agreement in TGah group (not counting “Abstain”) It may be also possible to include additional elements in the upcoming F2F meetings if the majority of the task group can agree on those. In the long run, the mature version of that document (FR-EM) with which TGah will try a first official approval may be ready until this Autumn. Minho Cheong, ETRISlide 4 May 2011

5. doc.: IEEE 802.11-11/0810r0 Submission Meaning of Functional Requirements TGah Functional requirements –These requirements are derived from the document “11-10-0001- 13-0wng-900mhz-par-and-5c”. –TGah amendment must address the functional requirements defined in functional requirements document. –As defined in Selection Procedure document(0238r2), TGah functional requirements document also include evaluation methodology (network simulation scenarios) –They are an small set of very essential and key requirements without which we cannot call the amendment TGah. –Each requirement in the FR-EM document had better be described as a normative text without any specific number as possible. Minho Cheong, ETRISlide 5 May 2011

6. doc.: IEEE 802.11-11/0810r0 Submission Potential Contents of TGah FR-EM Documents Requirements Section –Elements inherited from the TGah PAR document, such as coverage, data rate, WLAN experience, coexistence. –Other essential and key requirements element as a brief normative text, without which we cannot name it TGah. Evaluation Methodology Section (depending on CM) –PHY performance –Comparison criteria –Traffic model –Network simulation scenarios –And so on. Minho Cheong, ETRISlide 6 May 2011
