To further improve the security of an OpenAir network, each
OpenAir product requires the same Security ID to establish
radio communication.   The Security ID is used on all OpenAir
products, both Masters and Stations.  This ID is encrypted and
stored on the OpenAir CompactFlash Card itself, not in soft-
ware.  It cannot be accessed, but you may change it.  However,
if you do change it, then you will also need to change the
Security ID on all of the other OpenAir devices in order to
reestablish communication.

The Security ID is a string of up to 20 alphanumeric characters.
There are 1,048,576 unique choices for the Security ID.  The
default Security ID for all OpenAir products is blank (an empty
string).

You may change the Security ID from within the Configuration
tab of the Proxim Status utility.  Refer to Chapter 5 for more
information on how to set the Security ID.

The Roam Config parameter allows you to determine how
tolerant a Station is to radio phenomena that can cause the unit
to roam from one OpenAir Access Point to another in order to
maintain a strong radio connection.

In areas with many OpenAir Access Points that provide heavy
overlapping coverage, set this parameter to Fast to maintain
high throughput for each mobile client.

In most networks, set the Roam Config parameter to Normal.
Throughput will not change noticeably, and an overabundance
of Access Points is not required.
