ATHEROS XR(9)

💖 Atheros XR 💖

Okay bestie, welcome to Atheros XR(9) from the Kernel API Manual — and it’s giving niche wireless lore, fr fr. Some of this information is based on Documentation from:

http://madwifi-project.org/wiki/ChipsetFeatures/SuperAG

Atheros’ eXtended Range — aka XR, the range enhancing extension — is a modulation scheme. It’s supposed to double the link distance between an Atheros XR-enabled client device and an Atheros XR-enabled access point. The way it does this? By increasing receiver sensitivity up to -105dBm, which is about 20dB above what the 802.11 specifications demand. Iconic. ✨

And on top of that, new (proprietary) data rates are introduced: 3, 2, 1, 0.5 and 0.25 MBit/s. Slay? Maybe. 💅

🫶 Important vibe check: you can use either XR or TURBO, but you cannot use both — they are exclusive. Pick one, bestie.

💀 Also note: we do not plan to support XR mode at least for now. You can get a mode similar to XR by using 5MHz bwmode.
