Note
When using iPCF, the following maximum data rates must be taken into accoun
when setting the access point:
Max. data rate
IEEE 802.11a/h
12 Mbps
IEEE 802.11b
11 Mbps
IEEE 802.11g

or an access point is a major
factor in the reduction of handover times. To use this function, activate the

list box and enter the channels on which access points
ode can actually be reached in the
Background scan channels
Background scan channels
text box
Here, enter the channels on which access points operating in iPCF mode can be
reached by the client. If you enter more than one channel, each channel must be
separated by a blank.
Transmit power
list box
When using antennas, it may be necessary to reduce the transmit power to avoid
exceeding the legal maximum transmit power or to restrict the visibility of the radio
link. If necessary, select the required reduction in transmit power here.
A reduction of transmit power may also necessary to avoid interfering with other
cells because a reduced transmit power means a reduction in the span of the cell.
Antenna Mode
list box
This list box specifies the use of the antennas.
If
Diversity
is set, the SCALANCE W78x uses the
only
antenna that allows the best
possible data transmission. For each WLAN interface, both antennas must be
connected. Both antennas should also be of the same type and they should also
illuminate approximately the same space. If an access point is operated with the
diversity setting and the two antennas span different cells, this can have negative
effects.
Otherwise, you must select the connected antenna. For the IWLAN-PB LINK,
select
Antenna A
(see 6.3.3 section Antennas).
Select this check box to restrict the number of channels on which the client
searches for an access point. This results in a reduction of handover times.
