Channels - HP jetdirect 175x Administrator's Manual

Channels

The band of radio signals used for IEEE 802.11b wireless
networking are segmented into specific frequencies, or "channels".
For IEEE 802.11b wireless networks, 14 channels are available. But
each country/region specifies the channels that are authorized for
use. For example, in North America, only channels 1 through 11 are
allowed. In Japan, channels 1 through 14 can be used. In Europe,
except for France, channels 1 through 13 are allowed. Because of
frequent changes to existing standards, you should check with your
local regulatory agencies for authorized channel use. Note that, in
most countries/regions channels 10 and 11 may be used without
restriction.
Channel selection on the HP Jetdirect wireless print server depends
on the Communication Mode (or topology) of the network.
G
In Ad Hoc (Peer-to-Peer) Mode, the HP Jetdirect wireless
print server will initially scan all channels for the network
specified by the Network Name (SSID), for example hpsetup.
If the specified Ad Hoc network is detected, the print server will
configure and use the channel that the network uses.
If the specified Ad Hoc network is not detected, the print server
will actively transmit and advertise itself using a selected
channel. By factory default, channel 10 (2457 MHz) will be used.
However, channel 11 (2462 MHz) is also available.
If the print server fails to associate with a network, it will
repeatedly scan on all channels and then actively transmit on
the selected channel (channels 10 or 11) until it associates with
the specified network.
G
In Infrastructure Mode, the channel will be determined by
the Access Point to which the print server connects. The HP
Jetdirect print server, as with other clients, will adapt its
channel to the one required.
The channels available on your HP Jetdirect wireless print server
depend on your print server model. For supported channels, see the
documentation included with your HP Jetdirect wireless print
server.
