This disclosure describes systems, methods, and devices related to coexistence network integration. A device may transmit a beacon frame or a probe response frame containing a security element that is not a robust security network element (RSNE) element to indicate opportunistic wireless encryption (OWE) support. The device may identify a first association request frame received from a first station device (STA) comprising an RSNE element with OWE Authentication Key Management (AKM) indicating a compatibility of the first STA with OWE. The device may identify a second association request frame from a second station device (STA) indicating no compatibility with OWE. The device may generate one or more encryption keys for securing data transmission with OWE-compatible STAs. The device may transmit encrypted and unencrypted versions of groupcast data frames to the first STA and the second STA.
