Hi Sevak,
Thank you very much for sharing your experience with us. May
I know the RTS/CTS values which you set at the CPE side? This value may be relevant
to your installation location and environment.
It means, you have done the adjustment only on the CPE
side, right?
Sometimes, you cannot change the settings in the AP side because
this value may affect the other CPE devices also.
Thanks again for your quick response.

experience with RTS/CTS and Threshold settings
Hi Seeni,
Yes, changing these settings made a dramatic difference in our network.
Our customer's CPE are not normally seen by the other CPEs since they are all
in apartment buildings. By following SB's suggestions, we changed the
values for RTS on CPE and Frag on APPO. This improved the network
performance slightly, but optimal performance came when we turned off frag on
APPO and only used RTS on CPE.
Hope this helps.

Hi,
In order
to achieve better performance and increase the throughput in the wireless link,
sometimes following adjustments are required in the AP and CPE devices.
Any one
has the FIELD EXPERIENCE with these 2 adjustments?
Once you
adjusted these values, did you get any positive improvements in the
performance?
Probably
WISP experts might know much more about. I would like to know about your field
experience.
I know
that we need to try with various values and it may be varies between one place
to another. But I really want to know your field experience and what
circumstances you have done the changes. Is it really helped or not?
The
following information is provided for the purpose of understanding the two
values.
Fragmentation
threshold adjustment is required to increase the reliability of frame
transmissions. This value determines the size at which packets are fragmented.
It means sending the packet as several pieces instead of one block. Normally,
the sB radios default value is 2346. This default setting will work most of the
time and no doubt about it. But some times when we deal with higher
interference, we need to lower down the values to improve efficiency in the
packet transmission which avoids the packet loss. The following link will
give more information on this.http://www.80211-planet.com/tutorials/article.php/1468331
RTS/CTS
adjustment is required to minimize collisions among hidden node problems. This
value determines the packet size at which the AP issues the request to send
(RTS) before sending the packet. As I mentioned before, the default values will
work most of the time. Sometimes, low RTS/CTS settings will improve the
throughput where many client devices are associating with AP or where the CPEs
are far away and can detect only the AP and not each other. This occurs when
the users and access points are spread out throughout the facility and you are
finding relatively higher number of re transmissions occurring on the wireless
LAN..

Any field experience and feedback much appreciated.
