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

would mean that the SCALANCE
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.

based on the exchange of status information before sending the actual data
(Hidden node problem). To minimize network load resulting from the additional

Beacons
Beacons are packets that are sent cyclically by a SCALANCE W78x to inform
clients of its existence. In the

which the SCALANCE W78x sends beacons.
