Subject: [ath9k-devel] Channel busy cycles
Date: Sat, 27 Oct 2012 15:24:08 -0400 [thread overview]
Message-ID: <508C34D8.9060607@mailservices.uwaterloo.ca> (raw)
In-Reply-To: <508996FF.8060003@mailservices.uwaterloo.ca>
Hello,
I record the 4 registers showing tx, rx, busy, and total cycles. In a
clean environment (checked with a spectrum analyzer) I expected to see
busy = tx + rx. however, we have found that actually busy = tx + rx +
constant. where this constant is rate dependent. For example for 54
Mbps, the constant is about 1000 cycles. I have to note that this is an
802.11g setup. Any explanation is appreciated.
Best,
Ali
