November 2005

Enterprise-level User Authentication via 802.1x and EAP

WEP has almost no user authentication mechanism. To strengthen user authentication, Wi-Fi Protected

Access implements 802.1x and the Extensible Authentication Protocol (EAP). Together, these

implementations provide a framework for strong user authentication. This framework utilizes a central

authentication server, such as RADIUS, to authenticate each user on the network before they join it, and also

employs mutual authentication so that the wireless user doesn’t accidentally join a rogue network that might

steal its network credentials.

ESSID (more commonly referred to as SSID – Short Set Identifier)

The identifying name of an 802.11 wireless network. When you specify your correct ESSID in your client

setup you ensure that you connect to your wireless network rather than another network in range. (See

SSID.) The ESSID can be called by different terms, such as Network Name, Preferred Network, SSID or

Wireless LAN Service Area.

Ethernet

International standard networking technology for wired implementations. Basic 10BaseT networks offer a

bandwidth of about 10 Mbps. Fast Ethernet (100 Mbps) and Gigabit Ethernet (1000 Mbps) are becoming

popular.

Firewall

A system that secures a network and prevents access by unauthorized users. Firewalls can be software,

hardware or a combination of both. Firewalls can prevent unrestricted access into a network, as well as

restrict data from flowing out of a network.

Gateway

In the wireless world, a gateway is an access point with additional software capabilities such as providing

NAT and DHCP. Gateways may also provide VPN support, roaming, firewalls, various levels of security,

etc.

Hot Spot (also referred to as Public Access Location)

A place where you can access Wi-Fi service. This can be for free or for a fee. HotSpots can be inside a coffee

shop, airport lounge, train station, convention center, hotel or any other public meeting area. Corporations

and campuses are also implementing HotSpots to provide wireless Internet access to their visitors and

guests. In some parts of the world, HotSpots are known as CoolSpots.

Hub

A multiport device used to connect PCs to a network via Ethernet cabling or via Wi-Fi. Wired hubs can have

numerous ports and can transmit data at speeds ranging from 10 Mbps to multigigabyte speeds per second.

A hub transmits packets it receives to all the connected ports. A small wired hub may only connect 4

computers; a large hub can connect 48 or more. Wireless hubs can connect hundreds.
