Transmit Power
In the Transmit Power list box, you can specify the output power of the
SCALANCE W78x. It may be necessary to reduce the transmit power when using
antennas to avoid exceeding the maximum legal transmit power. Reducing the
transmit power effectively r
Beacons
Beacons are packets that are sent cyclically by a SCALANCE W78x to inform
clients of its existence. In the Beacon Interval text box, you specify the interval
which the SCALANCE W78x sends beacons.
Only in the access point mode and with the client in the ad hoc mo
The Beacon Rate list box specifies the data rate of beacons. The higher the data
rate, the shorter the transmission range.

how often the SCALANCE W78x sends broadcast and multicast packets over the
wireless interface. If you enter 1 in this box, the SCALANCE W78x transmits
broadcast and multicast packets directly after each beacon (recommended setti
for normal network en
W78x collects the broadcast and multicast packets and sends them after every fifth
beacon.
Increasing this value allows a longer sleep mode for the clients but means a
greater delay for broadcast and multicast packets.
RTS/CTS
RTS/CTS (Request To Send/Clear To Send) is a method for avoiding collisions
based on the exchange of status information before sending the actual data
(Hidden node problem). To minimize network load resulting from the additional
protocol exchange, this method is used only when a packet size that you select
with the RTS/CTS Threshold is exceeded.
