TGax MAC ad hoc. TGax PHY ad hoc. Draft 0. Issue Draft 1. Draft 2. Ideally, you'll also see the PHY itself fall off as you move further from the nearest access point—a lower QAM means lower PHY and throughput, but longer reliable connection range—but the connections your devices negotiate between themselves frequently aren't optimal.
Adding to the confusion, many of the protocols in this table support varying channel bandwidth settings, with higher bandwidth meaning higher throughput, but fewer available channels and more problems with interference and multiple MIMO streams as well.
The SU stands for Single-User, and no matter how many streams a device has available, it can only talk to one other device at a time. Got an 8-stream Tough; you're only getting a single stream worth of transmission to that single device no matter how many other devices you've got clamoring for airtime. For example, a 4x access point four transmit RF chains, four receive RF chains, and four simultaneous data streams possible can simultaneously "talk" to one 2x laptop, and two 1x phones or tablets.
And that makes it much less attractive in battery-powered devices. You must login or create an account to comment. Further Reading A deep dive into why Wi-Fi kind of sucks.
