Network SSID   

The SSID is a unique ID given to the Access Point.  Wireless clients associating to Access Points must 

have the same SSID.  The default value 

Auto Detect

 will  cause the CompactWLAN to  associate 

with any Access Point that gives the fastest response.  You may also specify and SSID (Access Point) 

with which  you desire to connect.  Specifying an SSID for your  CompactWLAN is recommended 

because it will prevent you PDA  from unintentionally connecting to a different wireless network.  The 

SSID can be set up to

 

32 characters

 

and is case sensitive. 

 

Link Rate 

The  CompactWLAN provides various data rate options for you to select.  Data rate options 

include Auto, 1, 2, 1 or  2, 5.5, and 11  Mbps.  In most networking scenarios, the default 

Fully 

Auto

 setting will prove to be  the most efficient.  This setting will allow your CompactWLAN  to 

operate at the maximum  possible  data rate under any condition.  When the  signal strength drops 

below a certain level, the CompactWLAN will automatically switch to a lower data rate.  When the 

signal strength improves, the  CompactWLAN  will  automatically readjust the data rate until it has 

reached the optimal speed.  Linking at a lower data rate trades off speed for connection reliability. 

 

Packet Fragmentation

 

Packet sizes larger than the specified value will be split into fragments before transmission. 

 

Power Management

 

When Power Management is enabled, the CompactWLAN will go into Power Management mode to 

minimize power consumption.   

 

(NOTE: When Power Management is enabled, the Access Point must also support Power 

Management for the link to be maintained.) 

 

RTS/CTS

 

Medium Access

   

Turn on only if your Access Point supports RTS/CTS Medium Access.
