12. 1. The following report is based on TGn closing report 04-0532 which is contained in the slides above. TGn Committee Report – Posted to Web • TGn (High Throughput) achieved a significant milestone by completing the generation of its 4 selection criteria documents for Usage Models, Functional Requirements, Comparison Criteria and Channel Models. In compliance with TGn’s Selection Procedure, completion of these 4 documents allows the Task Group to release a Call for Proposals. The Call for Proposals will be issued on Monday May 17. • Specified within the CFP are three key dates • The posting of Letters of Intent (Friday, June 18) • Posting of Proposals and related documentation (Friday, August 13) • Presentation of Proposals (Monday, September 13) • 9 Technical presentations covering various suggestions for High Throughput MAC an PHY improvements were heard as well. • Activities planned for July include • Status of Call for Proposals • Technical Presentations • Overall TGn timeline • .19 liaison planning (joint meeting) • .21 liaison planning (joint meeting) • regulatory issues discussion with .18 • TGn organization/officer planning Source: 11-04-0824-00-000n-tgn-overview Jason Ellis, Staccato Communications

13. 1. IEEE P802.11 - TGn Backgrounder TGn will define the next generation standard for high speed wireless LANs. The group's basic goal is to develop a standard capable of providing at least 100Mbps throughput at the MAC service access point. This is expected to provide roughly three times the throughput of current standards 802.11g and 802.11a. TGn has defined comprehensive Functional Requirements, Comparison Criteria, Usage Scenarios, and Simulation Environments which must be addressed by the proposals in order to be considered for the final standard. Complete proposals must address all of the requirements. Partial proposals, will most likely address various aspects of the MAC or Physical layer, but do not need to fulfill all the requirements indicated in the complete complement of reporting documents listed above. A call for proposals was issued on May 17 and closed on June 18. Following the close date of a formal call for proposals, the chair of Task Group n (TGn), Bruce Kraemer, has compiled and issued the list of individuals who have indicated that they will present a proposal. The list of respondents includes 21indicating they will make complete proposals and 41 who wish to make partial proposals. Proposals must be posted for membership review no later than August 13. At the upcoming IEEE 802.11 meeting in July TGn will plan for proposal presentations which will begin at the meeting in September. Past experience with previous calls for proposals would indicate that due to consolidation and mergers the total number of presentations will be less than 61.
