Wireless Security - Teltonika RUT100 HSDPA User Manual

Channel. Select the channel for the wireless network.
Data rate. Set the maximum wireless network data rate.
Transmit power. Set the maximum transmitter radiation power.
ACK timeout. Set ACK timeout in order to adjust the timeout value for long distance
operation.
Fragmentation. Specify the fragmentation threshold (in bytes), which determines whether data
frames will be fragmented and at what size [256-2346/off/auto]. On the 802.11 wireless LAN, frames
exceeding the fragmentation threshold will be fragmented, i.e., split into smaller units suitable for the
circuit size. Data frames smaller than the specified fragmentation threshold value are not fragmented.
Default: off.
Note: Setting a lower fragmentation threshold value can help improve connection reliability in
noisy environments (where radio interference is present). This mechanism does add overhead and
therefore reduces effective throughput.
RTS. Specify the maximum packet size beyond which the wireless LAN card invokes it's
RTS/CTS mechanism [0-2347/off/auto]. Packets that exceed the specified RTS threshold trigger the
RTS/CTS mechanism. The card transmits packets smaller than this threshold without using RTS/CTS.
Default: off.
Note: Setting a lower RTS threshold value can improve connection reliability and throughput
in crowded wireless LAN environments (where many clients are trying to communicate
simultaneously). It adds a certain amount of overhead, but can compensate for this by reducing
bandwidth lost due to collisions.
Throughput enhancements (available only on G mode).
Fast Frames – packet aggregation and timing modifications.
Packet Bursting – more data frames per given time period.
Compression – standards based (Lempel Ziv) real-time hardware compression.
Quality of service (WMM). Check the box to enable applications such as audio, video and
voice to have higher priority than less-sensitive data applications.
User isolation. Check the box to isolate the wireless clients from communicating with each
other.
Inter AP client isolation. Check the box to enable internal wireless network users isolation.

Wireless security

Figure 14. Wireless network authentication settings.
Broadcast SSID. Check the box to enable SSID broadcast.
Authentication Method. Choose the authentication method for wireless network:
Open system – no encryption. It will let anyone within range and with the proper equipment
to connect onto your network within the router operating range.
WEP-64-bit – choose the 64 bit WEP security with one of four pre-shared keys.
WEP-128-bit– choose the 128 bit WEP security with one of four pre-shared keys.
WPA-PSK-TKIP – choose the WPA security with pre-shared key, encrypted by the TKIP
(Temporal Key Integrity Protocol) algorithm.
WPA-PSK-AES – choose the WPA security with pre-shared key, encrypted by the AES
algorithm.
