Proxim RangeLAN 802 8520 User Manual page 60

The higher the Link Quality number from a particular node, the greater the link. A Link
Quality number of 0 indicates that the node is no longer responding at all. This is the
most important parameter to watch to verify that you will be able to maintain a reliable
wireless connection. Note that the Link Quality number of RangeLAN802 8400
adapters may be low if those adapters are in their power saving mode when being
surveyed. As these adapters wake up, the Link Quality number may change, so
this number may not always be accurate.
Received signal strength (RSSI) indicates how strong a signal was received from a particular
node.
After using the Broadcast Site Survey, you can choose the Run Directed Site Survey to
check the packets per second and bytes per second measurements between the
RangeLAN802 Access Point and the node you select. The packets per second rate
provides the best indication of the strength of the wireless connection between two
radios. A sample Directed Site Survey is shown in Figure 10 below.
