As a forth step, you must assign a WLAN profile to a configured RFP. This can be done on the
DECT
base stations page of the OMM web service or on the OMP DECT base stations -> Device list page.
Note that specific radio settings for the RFP, such the channel-, 802.11abgn mode-, or antenna settings,
are also done in this step.

7.18.2 OPTIMIZING THE WLAN
Beacon Interval
Transmitting beacons requires transmission channel capacity. A shorted beacon interval increases the
WLAN network's ability to detect signals, thus improving its availability. At the same time, it increases the
network's ability to adjust the mutually negotiated signal strength. A longer beacon interval saves WLAN
air time and also reduces the power consumption of mobile WLAN clients.

RTS Threshold
If the network throughput is low or if many retransmissions occur, the RTS/CTS handshake can be
activated by reducing the RTS threshold value below 1500 byte. This can improve throughput, especially
in environments where reflection and attenuation cause problems for HF.

Fragmentation Threshold
In environments where there is lot of interference and poor radio quality, reducing the fragment size
below 1500 bytes can improve the effective throughput. However, transmitted data frames must be
fragmented, which means a higher load on the RFP’s processor.

DTIM Period
The DTIM period specifies the interval between transmissions of the broadcast and multicast packets. All
WLAN clients must be active during this interval. Increasing the DTIM period lowers the client’s power
consumption slightly. Not all programs can manage the increase in response times, however.

Channel Allocation
Every WLAN RFP must be configured to a channel. You should ensure that the channel settings do not
overlap. WLAN RFPs within range of each other should be configured at least five channels apart. When
the radio field is planned, the WLAN RFPs of foreign WLANs that may be operating in the vicinity must
be taken into account.

When planning the radio coverage for a two-dimensional area, please bear in mind that the distance
between any two base stations operating on the same frequency must be at least twice their range. The
range can be adjusted by lowering the output power level.
