will be deleted along with all other frames buffered for that station.
This process is done every 2 seconds.
Notice that although power save mode is set in the AP it will not effect
the APs’ power consumption, but only the handling and management.
• DTIM Period (read-only) – This is the number of dwells between
broadcast transmissions of messages for stations in power saving mode.
Note: This option is not activated yet.
• IP Stack – By default this parameter is enabled. If it is disabled, it will
improve performance, but IP support will not be available.
• Acknowledge Delay – Acknowledge delay is designed to increase the
performance in links LONGER THAN 20 KM. This parameter increases
the ACK timeout in the units, and therefore allows a more efficient
operation. When a BreezeNET unit transmits a certain packet, it waits
for a pre defined time interval (ACK Timeout) for an ACK packet to be
received. If the ACK is not received during that interval, the unit will
assume the transmission has failed, and will retransmit the packet. In
links longer than 20 km, that ACK timeout is not long enough for the
ACK to arrive to the other side on time, and therefore unnecessary
retransmissions are made, causing the performance to drop. This
parameter increases the ACK timeout and allows the ACK to arrive to
the other side on time, in links longer than 20 km.
Note: Acknowledge delay must be enabled on both sides of the link, when the distance is
greater than 20 km. If used in links shorter than 20 km, a significant performance drop may
occur.
3.5.4. Radio
The Radio menu contains the following major parameters:
• Hopping Standard (read-only) – The Hopping Standard is a set of rules
regarding the radio transmission standard allowed in each country. Units
will work together only if set to the same hopping standard.
• Power level – Output power level at which the unit is transmitting.
There are two possibilities, Low (4dBm) or High (17 dBm) at the
antenna connector.
