Sooner or later, everyone notices their Access Point has an Advanced page where you can set TX to left/right/auto, and RX to left/right/auto.
So they ask:
Q: "Can I go faster if I dedicate left to TX and right to RX?"
Um, no you can't.
First off, this would violate the intent of the rather primitive diversity mechanism used in most WiFi Access Points.
The point of diversity is that during a given time-slice, the AP makes some sort of judgement about which is the best antenna for the client it's talking to, and prefers using that one. Later it judges again. By selecting one antenna element, you effectively prevent the access point from potentially making a better choice. For most household uses, this will probably slightly degrade your operations. It's not evil, you just aren't helping matters any and might be limiting the AP's ability to do job as designed.
But what people are really asking is about tricking the unit into full-duplex operation - sending and receiving at the same time by using both antennas. Can you do that?
No, you cannot.
See those posts aren't attached to different radios, they go to a single radio. And the single-radio is half-duplex, it cannot receive while transmitting. Think of a walkie-talkie or a speakerphone vs. a standard telephone conversation, which would be full-duplex. Full-duplex is simply not possible with the single-radio setup in consumer grade wireless.
