ISSUE WITH BRIDGE AIR-BR1410A

I have two Air-Bridges 1.8 miles which when the two bridges was lined up and these are the best values ​​obtained after several tests

Values ​​are:

BR-1410A (root)     BR-1410A (non-root)

-58 dbi                            -60dbi

54 M                               54 M

Power 24

Ver IOS 12.4 (24D)JA2

The channel is the best in the middle with less than 30% of saturation

Tests were made with the wireless link using a tool Solar wins (wan-killer) to pass a traffic AIR-bridge to the other and had a favorable desempño as 22 megs, but when put in the wireless enlance produccione this began to problems generate 12 megawatts, causing slow users, IP calls cut.

Network traffic from one point to another not exceed the 10 Megas

Do you have some ideas?

Best regards

If you are doing VoIP across this bridge link, make sure QoS is correctly configured to get required priority for voice traffic. Below post may help you to determine what it involve.

Post "show dot11 associations " output of the Root AP to see how is the connection established during problamatic time.

Already have QoS configured on the two wireless links, these are my results to sh Dot11 associations

These values ​​are not to be in production for the new values ​​that require a window would need to put into production the Bridges.

Re: ISSUE WITH BRIDGE AIR-BR1410A

As per these values your bridge is established 48Mbps at the moment you get these statistics.

You mentioned you got 22 Mbps througput when testing which also reasonbaly accurate (remember due to half duplex nature you won't get uplink/downlink 54Mbps, but half)

What is the round trip deley between two VoIP endpoints when call is made across this bridge ?

Re: ISSUE WITH BRIDGE AIR-BR1410A

I don´t have this value that you request.

But The problem is not only with calls, affects the entire network for both voice and data. Because the  trouput low as 10Mbps or even less

And this happens only when we put it into production the wireless link
