8. Chair presents slide 9; EU RED
a. The transition has already started
i. RED in THE LAW as of June 13, 2016
ii. R&TTE expires June 12, 2017
iii. After June 2017, all devices must meet the RED requirements, i.e. R&TTE certifications during the transition must be re-certified
b. Following the deadline, ALL equipment to be placed on the EU market must meet the RED provisions
c. EN 300 328 published in the OJEU!
d. It appears that EN 301 893 will not be not published in time
i. EC has NOT approved use of v1.8.1 with note that v2.0.7 Receiver Requirements must also be met
ii. Passed ENAP; official publication date in August 19th, but could happen sooner
e. Some background: The adaptivity clause for fare sharing of the band, was good before, though WiFi was about the only user.
f. When 3GPP brought LAA/LTE into the band, now the sharing was not the same and IEEE 802.11 WiFi would lose. For the last almost 3 years it has been worked on.
g. The updates did get through ENAP and comment resolution. But the new adaptivity clause is having issues with some WiFi vendors and maybe 3GPP.
h. So the ETSI chair has asked for a year delay to work this out.
i. With all that, the original thought was 1.8.1 and 2.1.1 could work side by side, meeting the RED minimum receiver requirements. Though many questions here yet.
j. Then some discussion to create 1.9.1 with 2.0.7 receiver requirements, but old adaptivity clause. But the ETSI tech officer this morning, cannot get 1.9.1 approved as R&TTE is gone. Stay tuned.
9. Chair presents slide 10; EN 301 893 Proposal
a. The 5 GHz requirements document is still in NB voting
i. Due to emerge May 23, 2017
b. The Adaptivity clause may present issues for Wi-Fi devices
i. MCOT limit of 10mS can be exceeded
ii. Industry needs time to study and make changes as required
c. EC Legal Services cannot accept requirements that are not officially published
d. The Proposal (EC verbally endorsed)
i. Keep v1.8.1 in the OJEU with note that it does not include receiver requirements
ii. Accelerate v2.1.1 publication to meet June 13th date
iii. ETSI BRAN#93 to create v1.9.1: v1.8.1 with receiver requirements from v2.1.1
iv. When v1.9.1 is published (~October), withdraw v1.8.1
v. In June of 2018, withdraw v1.9.1

11. Chair presents slide 13 and 14; TG11#49 (17)0007 Minutes
a. Steve (Ofcom UK) proposed the following to be noted into the minutes:
i. The separation distances for typical power handsets to Wi-Fi could easily be 1 or 2m which leads to experienced blocking levels of around -30dBm and so the -32dBm option for 2380 / 2503.5 MHz in the draft of the category 1 table are supported.
ii. That the proposed -42dBm by WFA was what the standard currently required and this was therefore not an improvement in equipment performance but rather an improvement in the requirements of the standard which are currently poor.
iii. -42dBm blocking levels could not be supported at this stage
b. Following further discussions Steve also asked if the blocking level could be increased to -36dBm for the closest blocking frequency but the wanted signal could also be increased to -70dBm which is in line with the JRC findings of typical Wi-Fi signals.
c. Johnny Dixon (BT) provided the following statement:
i. BT continues to believe that, in order to protect (Cat 1) Wi-Fi devices from blocking due to 2.3 GHz LTE devices which are expected to proliferate across Europe, such Wi-Fi devices will in future need to employ better filtering, and hence meet a more stringent blocking level.
d. Magnus Sommansson (Qualcomm) provided the following statement:
i. It is not the role of the harmonized standard to provide the protection that BT envisions to be necessary across Europe. This is the type of protection that should be provided by individual product development specifications driven by market requirements.
e. Octavian Popescu (WFA) provided the following statement:
i. While accepting to further analyse the current proposal, Wi-Fi Alliance is of the opinion that levels provided in document 58 are an improvement as required by the legal framework and satisfy the purpose of the Work Item.
