Site Survey

The purpose of the site survey tool is to enable users to configure
their network with the appropriate number and placement of
Access Points for their wireless networks.  Start the site survey
tool using the <Site Survey> button on the Windows tool, or the
<Site Survey> button from the <Test / Utilities> box in the DOS
tool.  Both site survey programs show the Link Quality and
Signal Strengths of the other RangeLAN2 products on the net-
work.

Node address lists the RangeLAN2 card’s node address/serial
number.  The Master is always listed first with its node address
and Master Name (unless this unit is the acting Master).

The higher the Link Quality number from a particular node, the
greater the communication path.  A Link Quality number of 0
indicates that the node is no longer responding at all. This is the
most important parameter to watch on this screen in order to
verify that you will be able to maintain a reliable wireless connec-
tion.  Note that RangeLAN2 7400 PC Cards in doze mode will
report an artificially low Link Quality number.

An asterisk in the Activity column indicates that the last packet
sent was answered.  The lack of an asterisk means that the receiv-
ing unit did not respond to the packet.

Received signal strength indicates how strong a signal was re-
ceived from a particular node.  It is not necessarily indicative of
the throughput on the link.

If you check the Roaming Enabled box, you can roam about your
environment and as you leave the range of one Master, the site
survey will continue as you seamlessly re-synchronize to another
Master.
