Submission doc.: IEEE /0149r0 January 2015 Rich Kennedy, MediatekSlide 2 Abstract This document contains a summary of the ETSI TC BRAN#81 meeting that took place in Las Palmas, Gran Canaria December 16-19, 2015, with a focus on EN comment resolution and revision.

Submission doc.: IEEE /0149r0 January 2015 Rich Kennedy, MediatekSlide 3 BRAN Agenda Items New Work Items (WI) o ETSI Technical Report (TR) on Coexistence with EESS in 5 GHz o ETSI TR on Coexistence with ITS and Road Tolling in 5 GHz o ETSI TR on Coexistence with radiolocation in 5 GHz o DA2GC in 5 GHz with beamforming antennas o DA2GC in 5 GHz with fixed antennas o Revision of EN for compliance with the new Radio Equipment Directive (RED) EN GHz high performance RLAN – Comment Resolution

Submission doc.: IEEE /0149r0 The Radio Equipment Directive Since the early 1990s, all the EU Harmonised Standards for radio equipment have been created in compliance with the R&TTE Directive, governing placement on the market With the increasing demand for spectrum sharing, the EC had developed new guidelines aimed at improving spectrum efficiency, and addressing issues with the R&TTE Directive This is scheduled to go into effect in June of 2016, with mandatory compliance in June of 2017 o radio-equipment-directive.pdf radio-equipment-directive.pdf I plan to supply a summary of the RED and a list of potential issues for new IEEE standards Slide 4Rich Kennedy, Mediatek January 2015

Submission doc.: IEEE /0149r0 Summary Work Items approved o ETSI Technical Report (TR) on Coexistence with EESS in 5 GHz o ETSI TR on Coexistence with ITS and Road Tolling in 5 GHz o ETSI TR on Coexistence with radiolocation in 5 GHz o DA2GC in 5 GHz with beamforming antennas o DA2GC in 5 GHz with fixed antennas WI for EN RED compliance includes final resolution of paragraph LBT for Load Based Devices EN v1.7.3 (to become v1.8.1) was approved o Paragraph maintains the wording from v1.7.1 o Adds an alternate based on inputs from the Wi-Fi industry Slide 5Rich Kennedy, Mediatek January 2015

Submission doc.: IEEE /0149r0 Revision of EN The issue with Paragraph o LBT for Load Based Devices of v1.7.1 provided sufficient “adaptivity” to meet EC requirements while was the only technology in the band o The introduction of other technologies in compliance with could severely disadvantage Wi-Fi CableLabs, Broadcom and WFA submitted simulations showing this Wi-Fi could virtually be excluded where v1.7.1 compliant devices operated o Exponential backoff, the primary Wi-Fi to Wi-Fi coexistence mechanism not in the text New DFS test requirement, test uncertainties made approval of v1.7.x necessary at this time Slide 6Rich Kennedy, Mediatek January 2015

Submission doc.: IEEE /0149r0 The Arguments Wi-Fi industry proponents o V1.7.1 leaves Wi-Fi vulnerable to unfair sharing o Simulations by CableLabs, WFA and Broadcom clearly demonstrate this o Although proposed changes to Paragraph still need to be improved to ensure fair sharing, this first step is needed so that 3GPP LAA-LTE planning is based on a fair approach, not v1.7.1 Others o No changes should be made until a final solution is available o Not yet known what LAA-LTE is until their simulations are done, so how can IEEE know they will be disadvantaged o Keep v1.7.1 Paragraph Slide 7Rich Kennedy, Mediatek January 2015

Submission doc.: IEEE /0149r0 The Results The group approved v1.7.3 (to become v1.8.1) with both the v1.7.1 and Wi-Fi industry proposal as alternatives for Paragraph The first draft of the new version will not be written until June of 2015 The new WI, for RED compliance will resolve the duality well before June 2017, when EN is out of force For the next 18 months v1.7.1 vulnerabilities will remain in the Harmonised Standard Slide 8Rich Kennedy, Mediatek January 2015
