Active Channel; Access Point Information - Intermec EasyCoder PF2i Installation Instructions Manual

Chapter 4 — Setup in Fingerprint

Active Channel

802.11b/g operates on a number of diff erent channels, corresponding
to diff erent frequencies. Th e printer scans for a suitable access point and
channel. Th e selected channel can be read from the printer. Th e read-
only setup-variable "CHANNEL" can assume values from 0 up to 14
depending on the region setting. 0 signifi es that an association has not
yet been made, 1-14 is the currently selected channel.
SETUP GET "wlan","CHANNEL",A$
gets the current channel in A$.

Access Point Information

Th e printer associates with an access point. Th e read-only setup-variable
"AP_MAC" will assume the MAC address of the access point that the
printer is currently associated with. If no association has been performed,
the value of "AP_MAC" is "00:00:00:00:00:00".
SETUP GET "wlan","AP_MAC",A$
gets the MAC address of the associated access point in A$.
Signal Strength
An important tool when working out problems with wireless LANs
is a signal strength meter. Th e printer monitors the received signal
strength, and makes it available to the user. Th e read-only setup variable
"SIGNAL" assumes the value of the current received signal strength. Th e
value may vary from 0 (no signal) to 100 (maximum strength).
SETUP GET "wlan","SIGNAL",A$
gets signal strength in A$.
Speed
Depending on diff erent (radio) network parameters—such as distribu-
tion of access points, frequencies, number of clients, etc.—the network
card may select a lower speed than the maximum for better overall per-
formance. Th e selected speed (rounded down to whole Mbps) can be
read from the printer. Th e read-only setup-variable "SPEED" can assume
values from 0 up to 54 (Mbps).
SETUP GET "wlan","SPEED",A$
gets the speed in A$.
