IEEE and IEEE Standards Association (IEEE-SA) have published the IEEE 802.19.1-2018 standard, Part 19: Wireless Network Coexistence Methods. The new standard enables the IEEE 802 family of wireless standards to effectively utilize license-exempt or lightly licensed devices by providing standardized coexistence methods among dissimilar or independently operated wireless networks under general authorization. It will help ensure fair and efficient spectrum sharing.
Finalized in June 2018, IEEE 802.19.1 specifies radio technology independent methods for network-based coexistence among dissimilar or independently operated networks. The standard is defined for geolocation-capable devices operating under general authorization such as TV band White Spaces (TVWS), 5 GHz license-exempt bands, and 3.5 GHz Citizens Broadband Radio Service (CBRS) lightly licensed bands.
The standard introduces the following:
- Methods for leveraging the cognitive radio capabilities of license-exempt devices, including geolocation awareness and information database access;
- Coexistence discovery and information server for gathering and providing wireless networks coexistence information;
- Coexistence manager utilizing information from the coexistence discovery and information server, thereby enhancing the coexistence of the wireless networks;
- Coordination enabler, which communicates with the coexistence manager within the same coexistence system and with the coordination enabler within the other coexistence system; and
- Common coexistence architecture and protocols, as well as multiple profiles enabling cost-efficient and flexible deployment of the coexistence system in various scenarios.
