Subject: [Bloat] wifi AP switching time
Date: Tue, 01 Jan 2013 12:49:26 -0500 [thread overview]
Message-ID: <6584.1357062566@sandelman.ca> (raw)
A comment was made a month ago or so about how long it takes wifi APs
to switch from transmitting (unicast) to one station to another. That
there was quite a large latency here, and that this was one reason that
the AP designers wanted large buffers to accmulate, so that the
switching time could be amortized over a larger number of packets.
I'm looking for a definitive reference to this problem.
Will this be in the 802.11 specification, or is this an inherent problem
in the chipsets, not the physics?
