Signal Strength
An important tool when working out problems with wireless LANs
is a signal strength meter. The printer monitors the received signal
strength, and makes it available to the user. The read-only setup variable
“SIGNAL” assumes the value of the current received signal strength. The
value may vary from 0 (no signal) to 100 (maximum strength).
<STX><SI>wt,SIGNAL<ETX>
Transmits signal strength.
Speed
Depending on different (radio) network parameters—such as distribu-
tion of access points, frequencies, number of clients, etc.—the network
card may select a lower speed than the maximum for better overall per-
formance. The selected speed (rounded down to whole Mbps) can be
read from the printer. The read-only setup-variable “SPEED” can assume
values from 0 up to 54 (Mbps).
<STX><SI>wt,SPEED<ETX>
Transmits network speed.
Region (a.k.a. Regulatory Domain)
Some countries and regulatory authorities only allow the use of a subset
of the 14 channels specifi ed in the 802.11b/g standard. To make the
product world confi gurable the setup variable “.REGION” is used.
The region can only be set by personnel authorized by Intermec. If the
wrong region/domain is set, please contact your Intermec representative
immediately. Continued use of the EasyLAN Wireless network interface
with an incorrect REGION setting may be in violation of applicable
laws.
The region setting will not be reset to default, even if a factory defaulting
upgrade is performed.
