This behavior is a result of current iOS software's aggressive power-saving strategy.
Current iOS devices will typically disassociate from their AP shortly after their screen has been deactivated. They will periodically wake up, re-associate, che...
The buffering I mentioned is within the rate limiting and ATF scheduler implementation. Over the air we use the standard 802.11n A-MPDU aggregation mechanism so there is no interoperability issue.
I don't have any results showing the efficiency g...
It is true that rate limiting can reduce overall capacity. The primary reason for this is increased contention (as mentioned) and reduced MAC-layer efficiency due to smaller aggregation sizes. Modern WiFi is extremely reliant on the 802.11n aggrega...
