RE: [smartBridges] Which signal to read?

[sB Tech Support]

My understanding (please correct me if I'm wrong) is that I look at the CPE (ABO) simple monitor to tell me how well it "hears" the Access Point (APPO). Right? Yes, the values shows that how well hears the signal from the Access point   I look at the Access Point (APPO) simple monitor to tell me how well it "hears" the CPE (ABO). Right?   Actually access point doesn't poll the client, but CPE send the values to the AP through the wireless which will varies between the CPE and AP. This value may not be same on the AP side because of wireless medium behavior. We already aware of this, we will try to address this on our next version.   Thanks   Seeni, SB support   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ray Sent: Wednesday, July 16, 2003 10:39 AM To: '[EMAIL PROTECTED]' Subject: Re: [smartBridges] Which signal to read?   Now I'm confused...   My understanding (please correct me if I'm wrong) is that I look at the CPE (ABO) simple monitor to tell me how well it "hears" the Access Point (APPO).
