Cisco WiFi 7

 Wi-Fi 7 standard dictates the following security constraints which are applicable for Wi-Fi 7 compliant APs:

The security standards mentioned below are beaconed as Wi-Fi 7 clients. This is a deviation from the actual security constraint.

• Open authentication as Wi-Fi 7 is not permitted to associate.

• WPA1 as Wi-Fi 7 is not permitted to associate.

• WPA2 as Wi-Fi 7 is not permitted to associate.

• WPA3 is permitted with certain restrictions:

  • SAE(24/25) is permitted with GCMP-256.

  • SAE(8/9) is permitted. (This is a deviation from the actual security constraint.)

  • WPA2 PSK/802.1x with PMF is permitted. (This is a deviation from the actual security constraint.)

  • 802.1x-SHA256 with PMF is permitted.

  • Suite-B-192 with PMF is permitted.

Static vs. Dynamic Puncturing WiFi 7

One of the features of WiFi 7

Static Puncturing This is pre-configured for the entire Basic Service Set (BSS) and advertised by the AP via the Disabled Subchannel Bitmap in the EHT Operation element (e.g., in beacons). All devices in the network, including STAs, must adhere to this pattern and avoid transmitting on the statically punctured subchannels. Static puncturing is mandatory in Wi-Fi 7 for wider channels (80 MHz+).

Dynamic Puncturing This is decided per-transmission (per-PPDU) based on real-time channel assessment (e.g., interference from radar, other Wi-Fi, or non-Wi-Fi sources). It's optional in Wi-Fi 7 and allows for more flexible avoidance of temporary issues without changing the BSS-wide configuration.

Apple AWDL and WiFi Aware

The EU’s Digital Markets Act has forced Apple to abandon its proprietary peer-to-peer Wi-Fi protocol, AWDL, in favor of the open Wi-Fi Aware (NAN) standard. This means iOS 19 and beyond will support cross-platform direct communication, previously limited to Apple-only features like AirDrop and AirPlay. AWDL was known for high performance and seamless coexistence with infrastructure Wi-Fi, but it was closed and unavailable to non-Apple platforms. Wi-Fi Aware, already supported on Android, offers similar capabilities but is industry-standard and interoperable. The EU mandates Apple implement Wi-Fi Aware 4.0 by iOS 19, and 5.0 within nine months of its publication. It also requires parity in functionality between AWDL and Wi-Fi Aware until AWDL is fully deprecated. Apple is not allowed to throttle or hinder performance on the standard. This marks a significant regulatory push against Apple’s closed ecosystem. Developers and users benefit from enhanced cross-device connectivity. Ultimately, this move signals a shift toward open, interoperable wireless communication across mobile platforms.
