WLAN mode: Selection of a specific WLAN mode
Channel: Offers the opportunity of either selecting a specific channel or the automatic
channel search function.
Note:
If the Intelligent Channel Selection (ICS) function is active, all ads-tec Access Points
in a local Ethernet segment are interlocked and optimize their channel selection on the
basis of different parameters. Here both the signal propagation ratios between the
devices are recorded and measured and other interfering Access Points outside the
network are taken into consideration. An ads-tec Access Point starts ICS measurement
during the booting process if the option is activated for the first time or the Remeasure
Timer has expired (visible by alternately flashing (red/green) LEDs on HOST port). The
measuring phase takes ~100 seconds. During this time, WLAN Clients cannot login at the
AP. If 5Ghz are configured with the DFS, the time up to readiness is extended to ~160
seconds.
Transmit rate: Allows manual or automatic setup of the Mbit rate.
CTS/RTS threshold: A signal is transmitted to the Access Point if a packet to be transmitted
has a size which exceeds the value setup in this item. The Access Point then reserves the
channel for this packet.
Fragmentation threshold: If a packet exceeds the value set up in this item, the packet will
be fragmented and divided into smaller packet units.
Note:
This fragmentation threshold cannot be used with the WPA encryption standard turned
on.
Longdistance:
If a large distance must be overcome between 2 devices the timeout for specifying the
distance may be increased here. The longer timeout setting causes the Access Point to
wait longer for proper reception of a response from the remote terminal.
Transmission antenna:
By selecting the transmission antenna you can decide if the transmission antenna should
be selected automatically or set up manually.
Antenna gain: The antenna gain can be used in order to gain higher transmission power.
Furthermore, it is limited by valid regulations of the respective country.
Example: An antenna with the value of 10dbi and a cable with the value of 3 db are used.
The value for the antenna amplification in this case amounts to 7dbi.
Power constraint:
The power constraint limits the Access Point power to the indicated value. The value
entered here is transmitted to all clients having access to the Access Point.
