Bridge GUI Guide: Network Configuration

WARNING:
The
FCC (the Bridge’s
default regulatory do-
main) requires anten-
nas to be professionally
installed; the installer is
responsible for ensur-
ing compliance with
FCC limits, including
TX power restrictions.
3.3.2.6
Tx Power Mode and Tx Power Settings
The default transmit power level for all radios is
Auto
, which
directs the Bridge to automatically set the transmit power at the
maximum allowed for the selected
Band
,
Channel
,
Network
Type
and
Antenna Gain
(refer to sections 3.3.2.2 through
3.3.2.5) by the regulatory domain established in
Country Code
Alternatively, you can specify a transmit power level for the
radio. As for
Auto
power-level selection, the set of usable
values for
TxPower
is a function of the Bridge’s regulatory
domain, in combination with its
Band
,
Channel
,
Network Type
and
Antenna Gain
settings for that radio.
The power at which radios are permitted to transmit is subject
to the applicable regulatory domain. You must configure the
Bridge with accurate values in order to comply with local
regulations. Consult your local regulatory authority for
applicable specifications and requirements for radio devices
and transmissions.
In environments with a dense distribution of APs (and resulting
potential for interference), it may be desirable to select a lower
Tx Power
setting than the default (
Auto
) for a radio using the
802.11g band. The
Auto
setting is otherwise appropriate for all
radios.
You can configure
TxPower
only in Advanced View.
3.3.2.7
Distance
The
Distance
setting configures the maximum distance for
which a radio in a mesh network must adjust for the
propagation delay of its transmissions.
Distance
is set in kilometers (the default) or miles, according to
the global
Radio Units
setting (Section 3.3.1.2), in increments of
1 and values from
1
to
56
km or
1
to
35
miles.
In a network deployment, the
Distance
setting on the networked
radios of
all
member Bridges should be the number of
kilometers (or miles) separating the two Bridges with the
greatest, unbridged distance between them. In Figure 3.7, the
Distance
setting would be
3
kilometers: the longest distance in
the network between two Bridges without another Bridge
between them.
Propagation delay is not a concern at short range. At distances
of one (kilometer or mile) and under, you should leave the
setting at
1
(the default for both radios).
