Statistics
This section is divided in 3 windows: LMAC (Lower Mac), UMAC (Upper Mac),
and Ethernet, which can be accessed from the Statistic Summary Page.
LMAC Statistics
The LMAC functions occur in the radio chipset. While the UMAC divides the
statistics into clean and failed packets, LMAC defines why packets failed.
This window contains three tabs: TX, RX and INT. TX and RX values are useful
to ISPs and other users. The INT (internal) statistics are intended for use by
Tranzeo Wireless Technical Support.
You can click onto each speed level and see how the traffic breaks down. In the
TX statistics, there should little to no Tries at Series 2, 3 or 4. The radio will try to
send a packet 4 times at Series 1 and then will try the next series 4 times. In the
RX statistics, you should look for bad CRCs and bad decrypts for signs of RF
interference or Fresnel interference links. Bad PHYs generally are caused when
the radio is unable to decode the packets due to noise.
Note
:
Communication between access points and CPEs always occurs at the lowest rate.
In a normal link, you should see a fair number of transactions at the lowest rate.
