Outline of the FLEXLAN-DS540 series
The FLEXLAN DS540 series is a wireless LAN PC Card adopting OFDM in the 5 GHz band, which has
the following features.
Features of the FLEXLAN-DS540 series
IEEE 802.11a compliant, 5 GHz band wireless LAN
The FLEXLAN DS540 series conforms to the new wireless LAN standard specification “IEEE 802.11a”
that applies to the OFDM encoding scheme in the 5 GHz band with less radio interference. The 5 GH
band wireless LAN provides a clearer radio communications environment than the 2.4 GHz band
wireless LAN.
The FLEXLAN DS540 series is classified as “radio equipment for a radio station in a low-power data
communications system” defined in the Wireless Telegraphy Act, requiring no radio transmission
license.
Data transfer rate of 54 Mbps
The product switches its data rate automatically to 54, 48, 36, 24, 18, 12, 9, or 6 Mbps depending on the
radio conditions. It will be provided with a link speed setting feature focusing on speed and stability.
Robust security provided
The FLEXLAN DS540 series supports the 64-, 128, and 152-bit types of WEP(RC4). Using WEP in
combination with WSL (Wireless Security Link with a proprietary cryptography) provides more robust
security. WEP can be used single-handedly, too. The FLEXLAN DS540 series will also support IEEE
802.1x specifying the latest protocol for security.
Capable of using 11 Mbps and 54 Mbps systems at the same time
You can install a 54 Mbps wireless LAN system while maintaining an existing 11 Mbps wireless LAN
only by inserting an 11 Mbps wireless CF card of FX-DS110-CFC (separately available) at an access
point. A flexible system can be implemented, for example, by constructing an 11 Mbps wireless LAN in
the open air where the use of the 5 GHz band is restricted by the Wireless Telegraphy Act and a 54 Mbps
wireless LAN indoors.
Capable of interconnection with a Wi-Fi compliant wireless LAN device
The FLEXLAN DS540 series can communicate, using basic features, with a Wi-Fi compliant device such as a
non-FLEXLAN wireless LAN card, wireless LAN integrated notebook PC. With this feature, you can get the
most out of wireless LAN resources.
Note! This feature does not guarantee the connection of the FX-DS540-PCC to all of Wi-Fi compliant devices.
Enhancements such as IP tunneling can be used with a product other than the FLEXLAN series.
Multi-channel support
Four channels (channels 34, 38, 42, and 46) can be used. Using different channels for wireless networks
adjacent to each other prevents radio interference and improves the throughput of either network.
IP tunneling function *1
Even when a wireless terminal with a fixed IP address assigned moves to (roam) a segment different in
IP beyond the router, you can continue communication without making changes to settings.
