Bridge GUI Guide: Network Configuration
61
NOTE:
If you
change the
Coun-
try Code
in effect on the
Bridge to a domain in
which current radio set-
tings are not permitted,
the relevant value(s)
will revert to default(s),
and reconfiguration op-
tions will be confined to
permissible values.
In addition, the Bridge uses your entries for
Network Type
and
Antenna Gain
(refer to sections 3.3.2.4 and 3.3.2.5,
respectively) to calculate allowable
TxPower
settings. These
settings are therefore also subject to regulatory compliance
requirements.
When
Advanced Radio
operation has not been licensed on the
Bridge (the default), transmission by the Bridge’s 802.11a
radio(s) is restricted to channels in the UNII-3/ISM
4
band of the
5 GHz bands. Outside of the United States, this restriction can
cause dual-band radios to be automatically reconfigured from
802.11a to 802.11g operation and radios that can use only the
802.11a frequency band to be disabled altogether (and their
configuration fields greyed out).
When
Advanced Radio
is licensed, the Bridge’s 802.11a
radio(s) can use additional licensed and unlicensed
frequencies. Contact Fortress Technologies for additional
information.
An
Advanced Radio
license permits the Bridge’s 802.11a
radio(s) to be used, in the 802.11a band, in any of the countries
on the default
Country Code
list (Section 3.3.1.3) and in any of
the additional countries in which the Bridge can be operated
when
Country
is licensed.
Country Code
is described in Section 3.3.1.3. Features
licensing is covered in Section 6.3. Per-radio settings are
described in Sections 3.3.2.1 through 3.3.2.10; step-by-step
instructions for changing them follow these sections.
3.3.2.1
Radio Administrative State
The
Admin State
setting simply turns the radio on (
Enabled
) and
off (
Disabled
). Bridge radios are
Disabled
by default.
Although a radio’s
Admin State
always remains at its configured
value, the actual operational state of the Bridge’s internal
radios is subject to the regulatory domain in which the Bridge is
operating (refer to Section 3.3.1.3). In some cases, radios that
can use only the 802.11a frequency band must be
automatically disabled (their configuration fields greyed out) in
order to bring the Bridge into compliance. Refer to Section
3.3.2 for more operational detail, and consult your local
regulatory authority for the applicable specifications and
requirements for radio devices and transmissions.
CAUTION:
Radios
used to form a net-
work (Section 3.2) must
use compatible trans-
mission and reception
settings.
3.3.2.2
Radio Band
The
Band
setting selects both the frequency band of the radio
spectrum a Bridge radio will use (for dual band radios) and
whether it will use the 802.11n standard for wireless
transmission/reception (for radios that support the option).
