An example of when you can disable this option is when your wireless device is a
hand-held scanning device communicating to a network via a single protocol system.
•
Maximum Sleep Duration. This is the listen interval in milliseconds that the client
applies to verify if there is traffic on the network addressed to the client. You should
not change the default value of 100 milliseconds, since this may interfere with the
operation of the network operating system.
However, a value between 100 and 500 milliseconds may be considered when
operating a wireless powered hand-held terminal connected to a network infrastructure
that can handle a less critical latency for optimal performance.
Security
The following lists the types of security in a RoamAbout wireless environment:
•
Network operating system security
•
RoamAbout Access Point Secure Access
•
Wired Equivalent Privacy (WEP) Encryption
•
Simple Network Management Protocol (SNMP) community names
•
Console port password
Network Operating System Security
To access networking data or services, a wireless client needs to run an appropriate network
operating system. Most network operating systems use standard security measures such as
login names and passwords.
When you follow the standard network security procedures and guidelines recommended
for your network operating system, an unauthorized user cannot access network data or
services without the appropriate user name and password.
For detailed information, consult the documentation that came with the network operating
system or refer to the reseller of your LAN software.
RoamAbout Access Point Secure Access
When Secure Access is enabled, the Access Point denies access to wireless clients that do
not use the correct wireless network name. When Secure Access is disabled, the Access
Point allows access to clients that use ANY (all uppercase) as the wireless network name
or have a blank wireless network name.
