Outline of the FLEXLAN-DS540 series
The FLEXLAN DS540 series is a wireless LAN devices adopting 5GHz band OFDM, which has the
following features.
Features of the FLEXLAN-DS540 series
It conforms to IEEE802.11a/b/g standard(Lisence is not needed).
The FLEXLAN DS540 series corresponds to the wireless LAN standard IEEE802.11 a/b/g and you can
select the wireless Lan standard for the various purpose of constructing a network.
IEEE802.11a can coustruct the 5 GHz band wireless network with high-speed and less radio interference.
The 5 GH band wireless LAN provides a clearer radio communications environment than the 2.4 GHz
band wireless LAN.
IEEE802.11g allows you to construct a 2.4-GHz band wireless network compatible with IEEE802.11b
remaining popular so far. The network conforming to this standard can utilize resources of existing
IEEE802.11b compliant products, accepting smooth migration from an IEEE802.11b 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
IEEE802.11a/IEEE802.11g switches its data rate automatically to 54, 48, 36, 24, 18, 12, 9, or 6 Mbps
depending on the radio conditions.
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
IEEE802.1X(EAP-TLS) specifying the latest protocol for security.
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.

1. Before Using the Product
FX-DS540-APDL-U 3
Note! This feature does not guarantee the connection of the FX-DS540-PCD 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
Thirteen channels (channels 36, 40, 44, 48, 149, 153, 157, 161) for IEEE802.11a and eleven channels
(channels from 1 to 11) for IEEE802.11b/IEEE802.11g can be used at the same time. Using different
channels for wireless networks adjacent to each other prevents radio interference and improves the
throughput of either network.
IP tunneling function
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.
Station feature
Two wired LANs can be interconnected between an access point and a station.

2. Functions and Wireless Link Mode
This chapter describes the major functions of the FLEXLAN DS540 series as a wireless LAN system and
the wireless link modes of the FX-D540-APDL along with configuration examples of networks available
in the wireless link modes.
Roaming Function
The roaming function maintains the connection to the LAN by automatically changing the access point
to which the user unit is connected when the unit moves. If access points are positioned so as to cover
the entire area where the wireless LAN is to be available, the user unit can be used from anywhere.
When the wireless link mode of a FLEXLAN-DS540 user unit is “Standard Infrastructure” or “Compatible
Infrastructure”, it is designed to continuously monitor the AP (access point) signal strength and change to
the AP that provides the most reliable communications.
In the following example, the signals from the APs do not cover the entire range in which the mobile
station UU1 moves and therefore the connection to the wired LAN is lost when UU1 is in position (2).

IP Tunneling Function (To be supported in the near future)
In TCP/IP, packets belonging to different network groups cannot normally be used. However, a
technique called tunneling or IP tunnel technology can be used to temporarily modify packets belonging
to different network groups so that they can be used. This technique can enable user units to
communicate with the wired LAN as usual even when connected via an AP from a different network
group.
The following example shows how user unit UU1, which belongs to network group A, can connect via a
router to terminal PC1, also in network group A, despite UU1 being connected to the LAN via AP2
which belongs to network group B.
