WInnForum Launches Project Focused on Passive, Active Spectrum Sharing
Wednesday, July 28, 2021 | Comments

The Wireless Innovation Forum (WInnForum) approved a new project on passive and active spectrum sharing (PASS).

The PASS working group will concentrate on co-existence and spectrum sharing between passive (non-transmitting) services, such as radio astronomy and earth remote sensing, and active services such as mobile broadband.

Among other tasks, the group will investigate extending commercial spectrum sharing techniques adopted by WInnForum standards, such as the 3.5 GHz spectrum access system (SAS) and the 6 GHz automated frequency coordination (AFC) system, to bidirectional sharing opportunities between passive and active systems. The work of the group will recognize that passive systems, which are receive-only, typically require extraordinary protections due to the high sensitivity of their receiving systems and that they could benefit from improvements in opportunistic access to bands otherwise allocated to active systems. The group will also investigate potential opportunities for active systems to better utilize spectrum that is co-allocated to passive systems when and where passive services are not using it.

The PASS project will be co-chaired by Dr. Kevin Gifford, a research professor of computer science at the University of Colorado-Boulder with expertise in wireless communications, and Dr. Andrew Clegg of Google, who serves as WInnForum's chief technical officer and is a former radio astronomer.

The online kick-off meeting for the project is August 3. Participation in the committee is open to representatives of all WInnForum member organizations. Trial memberships are available for organizations that wish to explore participation in advance of joining as full members. Non-member observers and subject matter experts may also be invited to participate in future meetings of PASS at the discretion of the committee steering group.
