Under ideal conditions—low traffic and good RF signal path—the
latency for units operating in the TCP mode, will typically be around 5
ms in each direction. However, when UDP multicast traffic is trans-
ported, the outbound packet latency (from AP to remote) is dependent
on the beacon period.
UDP multicast packet latency can be minimized by setting the
Beacon
Period
to
Fast
(52 ms). Changing beacon rate to
Fast
will result in an
average latency of 31 ms, assuming outbound packets wait for a beacon
transmission 50% of the time (26ms) plus the normal packet latency
(5 ms).
Data Compression
Enabling this option uses an LZO compression algorithm for
over-the-air data. Varying levels of data reduction are achieved
depending on the nature of the data. Text files are typically the most
compressible, whereas binary files are the least compressible. On
average, a 30% increase in throughput can be achieved with compres-
sion enabled.
Compression is used on data packets of 100 bytes or more, including
Ethernet, IP, and TCP/UDP headers.

MAINTENANCE
In the normal course of operating a wireless network, you will want to
take advantage of product improvements, and to read and archive the
configuration of your individual transceivers using the Maintenance
Menu. This section provides detail information on how to take advan-
tage of these services.
The maintenance tasks are:
•
Reprogramming
— Managing and selecting the unit’s operating
system firmware resources.
(
See “Reprogramming Menu”
on
Page 92
)
•
Configuration Scripts
—Saving and importing data files contain-
ing unit operating parameters/settings.
(
See “Configuration
Scripts Menu”
on Page 97
)
•
Authorization Key
—Alter the unit’s overall capabilities by
enabling the built-in resources. (
See “Authorization Keys Menu”
on Page 105
)
•
Auto-Upgrade/Remote-Reboot
—Configure when remotes retrieve
new firmware versions from the associated AP, and whether or
not they reboot to the new firmware after receiving the new
firmware. (
See “Auto-Upgrade/Remote-Reboot Menu” on
Page 106
)
•
Radio Test
—A diagnostic tool for testing RF operation.
(
See “Radio Test Menu” on Page 107
)
