  5. SC Operating Rules • Anybody can vote, present, and make motions • Participation in SC during 802.11/15 WG Plenary or Interim counts towards 802.11 or 802.15 voting rights • All motions must pass by a 75% majority Rich Kennedy, MediaTek

  6. Other Guidelines for IEEE WG Meetings • All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. • Don’t discuss the interpretation, validity, or essentiality of patents/patent claims. • Don’t discuss specific license rates, terms, or conditions. • Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings. • Technical considerations remain primary focus • Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets. • Don’t discuss the status or substance of ongoing or threatened litigation. • Don’t be silent if inappropriate topics are discussed… do formally object. • --------------------------------------------------------------- • If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at patcom@ieee.org or visit http://standards.ieee.org/about/sasb/patcom/index.html • See IEEE-SA Standards Board Operations Manual, clause 5.3.10 and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details. • This slide set is available at https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.ppt Rich Kennedy, MediaTek

  7. Introduction • Purpose • Improve the working relationship between the technical experts and the regulatory specialists, especially when it comes to critical technical issues • Scope • The group will review new regulatory changes or impending changes affecting 802.11 and 802.15 standards • Each meeting will focus on the most critical issue at the time • Critical Issue Focus • Direct impact on IEEE 802.11 and 802.15 current and future standards • Response/Input deadlines • Coordination with IEEE 802.18 (RR-TAG) • Coordination with the Wi-Fi Alliance • Outputs from this group must go through 802.18 Rich Kennedy, MediaTek

  8. Currently Open Items • FNPRM FCC 14-49: 3-tiered sharing in 3550-3700 MHz • Comment period closed July 14th • Reply Comment period closes August 15th (two week extension) • WG SE24 5 GHz Band Sharing Studies • WI 52 looking at 5725-5925 MHz band sharing • August 25th meeting preparation • Wi-Fi Alliance providing input; needs sharing studies, IEEE 802.11 information • Ofcom PSSR consultation closed • Dialog continuing • Concern with LTE at 2390 MHz interference into Wi-Fi and BT in 2400 MHz • Looking for proof and/or studies showing interference • Still waiting for FCC decision on Globalstar TLPS • Early indications are FCC will allow Rich Kennedy, MediaTek

  9. Ofcom Questions • Possible interference to Wi-Fi: • Have you experienced any impact on Wi-Fi as a result of LTE or WiMAX/WiBRO systems in the 2.3 GHz band (band 40 – BS or UE) or in fact from systems operating at the other end of the Wi-Fi band at 2.5 GHz (UEs in band 7 FDD or UEs and Base stations in band 41 TDD systems) • If so in which markets? • If so how did this manifest itself, did it appear as increased Wi-Fi congestion or some other problem? • Do you know if this was interference as a result of high power base stations, small cells, user devices or same device problems? And in what kind of operational scenarios? Rich Kennedy, MediaTek

  10. Ofcom Questions [2] • Possible mitigations: • We know that there are some small band pass filters available for Wi-Fi devices from a few manufacturers. Is this something that you use, or are considering using in your products? • If so will this be universal across your range of products or just in certain ones, if so does this relate to enterprise grade versus consumer grade equipment?. • We have also considered that if in some cases interference was to occur then making increase use of the 5 GHz Wi-Fi band may provide some benefit. Do you have device / component solutions that are 2.4 GHz only or are all your current product range dual band? Rich Kennedy, MediaTek

  11. Ofcom Questions [3] • Possible mitigations (cont’d): • Can you provide us some ideas as to the replacement cycle of your devices so we can understand at what point the legacy devices may been replaced out of the market? • Are there other mitigations that you think are possible other than improved filtering on the Wi-Fi input such as increased dynamic range or different scheduling and packet retry techniques? • If different retry algorithms did improve performance in the presence of mobile communications signals, is this something that can be applied to legacy devices via new firmware uploads or would it be for new devices only? • Please will you provide us with some details on the unit cost of additional filters or other mitigations so we can estimate the scale of the impact? Rich Kennedy, MediaTek

  12. Ofcom Questions [4] • Dual system devices: • If you make devices that have or will have 2.3 GHz TD-LTE and Wi-Fi radios within them, how will you ensure coexistence between these two systems in the same device? Will this be based on scheduling between them or on improved receiver performance or some other mechanism? • Finally, is there anything else that Ofcom as a regulator should do to reduce the risk of coexistence problems between LTE and Wi-Fi? Rich Kennedy, MediaTek

  13. 5 GHz Petitions for Reconsideration • Responses required by August 14th • Opposition to Cambium • Support for Mimosa Rich Kennedy, MediaTek

  14. Mimosa Petition Details • IN FCC ET 13-49 5 GHz 1st Report and Order Petitions for Reconsideration: Regarding OOBE, While others want 15.247 reinstated, Mimosa proposes to revise Sections 15.407(b)(1) and (4) by adding at the end of each the following: “If transmitting antennas of directional gain greater than 6 dBi are used, the emissions limit shall be increased by the amount in dB that the directional gain of the antenna exceeds 6 dBi.” • 1) Not apply the 3dB penalty for MiMo antenna systems per KDB 662911 • 2) For OOBE where antenna exceeds 6dBi – OOBE limit is increased by 1dB for every 3dB antenna exceeds 6dBi • 3) OOBE measurements for outdoor systems where antenna gain exceed 6dBi and no power reduction from 1W is done , you could use 100kHz BW RBW/VBW • Chair reads slide 14 Other regulatory updates – EN 300 328 v1.9.1 will not be ready 2015 Jan 1, delayed until March. The v1.8.2 test procedure may be acceptable. Rich Kennedy, MediaTek

  15. Other Regulatory Updates • EN 300 328 v1.9.1 will not be ready for January 1, 2015 • Industry will have to deal with test complexities, at least until March 2015 • May ask okay to use test process from v1.8.2 (preview of v1.9.1) • China 5.8 GHz status? Rich Kennedy, MediaTek
