Ethernet Switch

A switch is an active network device for connection of network segments.
It has several ports to which network devices are connected.. The switch distributes the incoming data packets target oriented, which means only to the ports target devices are connected to. Furthermore the switches distinguish according to the layer of the IOS/OSI model they work on. A distinction is made between layer-2 and layer-3 switch devices. A switch can either be managed or unmanaged, depending on whether there is an ability to be configured and controlled (manage) by the user or not. The available cRIO modules for networking are layer-2 (Ethernet), unmanaged switch devices.

WLAN

WLAN is a wireless local area network, which is defined by the standard IEEE 802.11. Wireless networks can be operated in different modes. The best known are ad-hoc and infrastructure. The IEEE 802.11 standard has different channel bandwidths (e.g. IEEE 802.11b). The operating range is up to 100 m. Depending on the environment, Wireless LAN can be used to cover even longer distances by using special antennas. The data security is accomplished with encryption standards like AES and WPA. The SEA cRIO modules for networking are compatible with the IEEE 802.11b, g standards and support multiple encryption mechanisms.
