RE: [smartBridges] MORE ABOS crapping out

[sB Tech Support]

For a 4 mile link and a 13 dB sector and using a 500 mw amps along with a 19 dBi parabolic grid antenna is really over killing �the system. You certainly do not need such a high o/p power for a 4 mile link which is the primary cause of interference and multipath interference.   Hence it is very difficult to diagnose a system with AMPS. We have seen in many cases when the operator has removed the AMP and do proper antenna design and deployments the performance has improved.   Please try to re design your system without the AMP and you shall see improved performance.   Vasu   sB Tech Support -----Original Message----- From: Blazen Wireless [mailto:[EMAIL PROTECTED] Sent: Thursday, August 21, 2003 12:01 AM Cc: [EMAIL PROTECTED]; sB Tech Support Subject: Re: [smartBridges] MORE ABOS crapping out   This is the client side that keeps going down. .   I have 13db 95* Sector ant on each APPO with 500mw amp the Client is aprox 4 miles away with 19db parabolic ANT High above the roof line RSSI is 85% and Link 95% at the client side at the APPO side it reads RSSI 90% and Link 85% complete opposite.    How do you want me to log the evens Simple monitor wont let me log more then one radio at a time? Or do you want me to log the info from the APPO??   If it were interference causing the link to go down then why are the other users next door and also 1 block over all okay pointing to the same APPO? I find it hard to believe that you would make a product that could not see some interference and NOT re associate? All the other stuff I have worked with sure it had some interference but it NEVER and I do mean NEVER dropped and did not come back up? it still stayed associated..   Seems to me like there is something else going on with the product?         ----- Original Message ----- From: SB Tech Support To: 'Blazen Wireless' Sent: Wednesday, August 20, 2003 8:45 AM Subject: RE: [smartBridges] MORE ABOS crapping out   Can you let us know what type of antenna is being used on the access point and also if considerable amount of fade margin was taken into consideration while choosing the gain of the antenna. Try to log the link status log files on the airBridge and  please let us know. This will let us know just before the during the disassociation if the RSSI and link quality was going bad. Because seems like interference among the system operating in the same channel is causing the link to go down.   We would like to identify what the exact cause of the problem is? Is it merely interference or the device on the client side?   With Best Regards,   Vasu (sB Support Team)   sB Tech Support -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Blazen Wireless Sent: Wednesday, August 20, 2003 10:32 PM To: '[EMAIL PROTECTED]' Subject: [smartBridges] MORE ABOS crapping out   Okay I give up I have 4 of the new radios I purchased with supposedly the new chi and the new firmware and they are still disassociating any wonderful ideas on what to try next.   1. I have tried everything I have tried in the past when this whole thing started so PLEASE SB don't tell me stupid stuff to check already since I know 100% it is not the installation. 2. When we went to look at the one yesterday it was thought to be heat related. We touched the ABO and it was Luke warm if at hottest. Link light (blue) was just flashing away NO association. RSSI 85% Link 95% GREAT signal and he keeps losing associating every day.   PLEASE PLEASE PLEASE let us know what's causing this.   This customer is hooked from the radio to a D-link 4 port router to his laptop as are most all my installs..
