Workshop Background and Motivation

Unlicensed spectrum has proven to be a source of very significant socio-economic benefits around the globe, starting in about 1999. The Wi-Fi Alliance recently estimated that the current global economic value of Wi-Fi operating in unlicensed spectrum (2.4GHz and 5GHz) is almost $2 trillion per annum. 

By its nature, unlicensed spectrum is a resource for sharing by everyone. In the near future, it is hoped that the 6GHz band will be made available globally for unlicensed use. It is vital that all technologies, including IEEE 802.11ax (currently being standardised by the IEEE 802.11 Working Group) and 3GPP NR-U (currently being standardised by 3GPP RAN), share the 6GHz band in a fair and efficient manner. 

The Coexistence Workshop has no decision making authority. It is hoped that workshop discussions will result in 3GPP RAN and the IEEE 802.11 Working Group making better informed decisions that promote mutually beneficial coexistence.

Workshop Invitation

The IEEE 802.11 Working Group are delighted to invite any interested stakeholders (including technology providers, solution providers, operators and users) to participate in a one day Coexistence Workshop being organized by the IEEE 802.11 Working Group, in collaboration with 3GPP RAN, in Vienna, Austria on 17 July 2019.

The primary objective of the Coexistence Workshop is to discuss issues related to fair and efficient shared operation by IEEE 802.11ax High Efficiency WLAN), IEEE 802.11be (Extremely High Throughhput) and 3GPP NR-U (New Radio Unlicensed) in the 6Ghz band, including:

       Sharing information on plans for use of future technology standards (particularly IEEE 802.11 and 3GPP NR-U) in the 6 GHz band

       Assessing coexistence issues and topics related to the simultaneous use of IEEE 802.11 and 3GPP NR-U technologies in the 6 GHz band, including coexistence criteria and mechanisms

       Discussing other related coexistence topics of interest, including deployment experience of 3GPP LAA/eLAA coexistence with IEEE 802.11ac in the 5GHz band.

Invitations to the Coexistence Workshop have been sent to and accepted by the following  industry and standards organizations::

·     3GPP RAN & 3GPP RAN1, who have indicated that approximately 35 3GPP RAN experts will be attending the Workshop

·     Wi-Fi Alliance

·     Wireless Broadband Alliance

·     GSMA  


     ·     5G Alliance for Connected Industries and Automation ( 5GACIA)

Workshop Call for Papers

IEEE 802.11 Working Group requests that any individual or organisation wishing to contribute one or more short papers to the Deployment update or Coexistence topics agenda items to submit an outline of the paper, explaining how the paper will support the Coexistence Workshop’s goals. Each presentation should focus on a single topic and aim to be about 10 minutes in length. Up to 10 minutes will be scheduled for discussion of each presentation.

The deadline for the submission of outlines is 12 May 2019. Outlines should be sent to the IEEE 802.11 Coexistence SC Chair (Andrew Myles at amyles@cisco.com), copied to the IEEE 802.11 Working Group Chair (Dorothy Stanley  at dstanley@ieee.org). Notifications of accepted outlines will be sent to the authors by 31 May 2019. Authors are required to submit their finalised presentation material by 1 July 2019.
