Follow up on ECC work item to study WAS / RLANs in upper 6 GHz band

Plenary ECC( 21) aaa 5 7 th ECC Plenary Meeting To be decided , 0 2 - 05 November 2021 Date issued: [enter date] Source: [enter source] Subject: Work Item Proposal for studies on Wireless Access Systems including Radio Local Area Networks (WAS/RLAN) in the 6425-7125 MHz band 2718435 186690 N 0 0 N Group membership required to read? (Y/N) Summary: I t is important that all the facts are available to CEPT A dministrations prior to taking a position on the future use of the 6425-7125 MHz band. With that in view, t his document proposes to study the possible technical and usage conditions under which Wireless Access Systems including Radio Local Area Networks ( WAS/RLAN ) operating in the 6425-7125 MHz band could coexist with existing users of the band . A possible W ork I tem for the relevant technical studies within ECC WG SE is outlined in Table s 1 and 2 below . Proposal: The co-signing CEPT A dministrations propose that the ECC Plenary tasks ECC WG SE , though a new W ork I tem , to study the possible technical and usage conditions under which Wireless Access Systems including Radio Local Area Networks ( WAS/RLAN ) operating in the 6425-7125 MHz band could coexist with existing users of the band . These studies should address: technical and operational characteristics of WAS/RLAN in the 6425-7125 MHz band ; sharing and compatibility issues between WAS/RLAN and incumbent services in the 6425-7125 MHz band ; any necessary mitigation techniques and conditions on WAS/RLAN that would facilitate sharing with the incumbent services. Background: Globally and i n Europe, there is a growing demand for licence-exempt Wireless Access Systems including Radio Local Area Networks ( WAS/RLAN ) to provide additional capacity and higher data rates as outlined in the following quotations: During the next years, technological advances and accelerating deployments of ultra-fast access networks (fibre, cable, and FWA) will provide speeds in excess of 1 Gbit per second to many European households, enterprises, and public institutions. Gigabit connectivity is one pillar of the EU Digital Decade and a pre-requisite to Europe’s Green transition and Digital transformation. Already today, some European operators are offering residential customers Fiber to the Home (FTTH) connectivity with data rates of 10 Gbits per second. By 2030, peak data rates between 50 and 100 Gbits per second are expected . These data rates will have to be made available to the users most of whom will be using their connected devices indoors, with most mobile devices being connected through Wi-Fi. Studies of human behaviour patterns show that Europeans spend more than 90% of their time indoors. In line with this observation, more than 80% of mobile data traffic originates or terminates indoors, and it is predicted that in the coming years, this value will increase to more than 90% . T o respond to these demands, additional spectrum needs to be considered for use by WAS/RLAN. From technical and economic standpoints, the 6425-7125 MHz band is the most attractive option for extending the WAS/RLAN spectrum, particularly as many countries around the world already authorized licence-exempt WAS/RLAN operation in the 5925-7125 MHz band. Previous studies that were conducted for the 5925-6425 MHz band and presented in ECC Reports 302 and 316 already addressed, amongst other scenarios, in-band WAS/RLAN coexistence with FS and FSS (Earth-to-space) which will also be the most relevant scenarios for the 6425-7125 MHz band. Additional scenarios for in-band WAS/RLAN coexistence in the 6425-7125 MHz band would need to address FSS (space-to-Earth) for feeder links of non-GSO MSS, RAS, EESS (passive) and SOS.

We hope Estonia will be able to support such a Work Item during the next ECC plenary meeting in early November. The Czech administration fully supports this proposal and are engaging with other administrations on the topic. If you would like to discuss this further with the CTU please do not hesitate to contact Pavel Sistek ([email protected]), Head of Policy and Strategy Unit at the Czech Telecommunication Office. Based on initial feedback from other administrations I'd like to emphasise we are only seeking a Work Item to undertake studies to see if WAS/RLAN could (or not) coexist with existing incumbents (mainly FSS and FS). This work item will not address WAS/RLAN coexistence with IMT. We appreciate work is ongoing within ITU-R WP5D under agenda item 1.2 but this is only considering IMT coexistence with incumbents. We believe it is important for Admins to have all the facts in hand before taking a final position on AI 1.2. If of interest, we would be pleased to organise a meeting together with industry representatives to discuss this further. Please also find attached the latest quarterly Wi-Fi 6E newsletter from the Wi-Fi alliance that provides an update on the policy and regulatory developments across EMEA, device availability and includes an interview with the head of the ASMG, Tariq Al Awadhi.

I am writing to ask you to consider raising a work item in the CEPT to study possible harmonised technical conditions for wireless access systems (WAS), including radio local area networks (RLANs), to provide wireless broadband services in the 6425-7125 MHz band. With the results of such studies, administrations would be in a better position to decide if WAS/RLAN and/or IMT are viable options for sharing with incumbent services and agree on the way forward before 2 the WRC-2023. Without such studies, it will be difficult for administrations to take an informed position on WRC-2023 Agenda Item 1.2. Changes since the 2017 EC mandate As you are aware, the 2017 EC Mandate harmonises spectrum for WAS/RLANs in the lower 6 GHz band (5945-6425 MHz) only, but there remains a case for expanding the frequency range to 7125 MHz. A viable 6 GHz WAS/RLANs ecosystem already exists; many countries including the U.S., Canada, South Korea, Brazil, Saudi Arabia (see attached infographic), are making the entire 6 GHz band (5925-7125 MHz) available under a licence-exempt regulatory regime. Further, the results of ECC studies for lower 6 GHz (5925-6425 MHz) show that low power indoor (LPI) and very low power (VLP) indoor/outdoor can coexist with the incumbents. Suggested next steps We note that the incumbents in the lower 6 GHz band (5925-6425 MHz) are practically the same as the incumbents in the upper 6 GHz band (6425-7125 MHz). But since there may be some differences, a new CEPT study is likely to be required. We understand that under CEPT rules there need to be at least five administrations to support a new work item, which could be proposed for consideration at the 56th ECC Plenary (28 June to 2 July 2021) for a non-binding technical study, such as a CEPT or ECC report. The WAS/RLANs ecosystem is willing to support this work with additional research and inputs as required. If of interest, we would be pleased to organise a meeting with industry representatives, before the next ECC plenary, to discuss this further. I look forward to hearing from you.
