5 Features

The SysKonnect SK-54C1 Wireless LAN Cardbus Adapter is comprised of highly integrated Marvell 802.11g/b chipsets. The chipsets consist of a radio frequency (RF) transceiver and an integrated MAC/Baseband WLAN client System-on-Chip device. Marvell chipset solutions are compliant with the IEEE 802.11g/b standard and support point-to-point and point-to-multipoint access that seamlessly connect to wired Ethernet and PC network LANs.

Wireless Modes

The SysKonnect Cardbus Adapter operates similar to Ethernet adapters except that a radio replaces the wires between communication devices. All existing applications that operate over Ethernet will operate over a SysKonnect wireless network without any modification or need for special wireless networking software.

The adapter supports the following network technologies:

•Ad-hoc (peer-to-peer group) mode

•(Access Point, AP) Infrastructure mode

Ad-hoc Mode

In Ad-hoc mode (also referred to as peer-to-peer mode), wireless clients send and receive information to and from other wireless clients without using an access point. In comparison to Infrastructure mode, this type of WLAN connection only contains wireless clients. Ad-hoc mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required. Two or more computers can establish an Ad-hoc network when within range of one another. Each computer dynamically connects to one another without additional configuration. Ad-hoc mode is used to network computers at home or in small offices. It is also used to set up a temporary wireless network for meetings.

Infrastructure Mode

In Infrastructure mode, wireless devices communicate with other wireless devices or devices on the LAN side wired network through access points. When communicating through wired networks, Cardbus adapters send and receive information through access points (APs). The access point receives the information and redirects it to clients, which then receive the infor- mation.

Access points are typically strategically located within an area to provide optimal coverage for wireless clients. A large WLAN uses multiple access points to provide coverage over a wide area. Access points connect to a LAN through a wired Ethernet connection. Access points send and receive information from the LAN through this wired connection. Most corporate WLANs operate in Infrastructure mode because they require access to the wired LAN in order to use services such as file servers or printers.
