802.11a Support Chapter 2. Features 802.11a Support 802.11 is a family of specifications for wireless local area networks (WLANs) developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). The four current specifications include: 802.11, 802.11a, 802.11b, and 802.11g. All four use the Ethernet protocol and carrier sense multiple access with collision avoidance (CSMA/CA) for path sharing, which allows a number of network users to pass packets on the netwo

Access Ports The 802.11b standard, also called Wi-Fi (Wireless Fidelity), is backward compatible with 802.11. 802.11b uses complimentary code keying (CCK) modulation to provide higher data speeds (up to 11 Mbps) with less multipath-propagation interference. 802.11b operates at the 2.4 to 2.5 GHz range. The WS 2000 Wireless Switch fully supports the 802.11b specification for association with Symbol’s suite of compatible Access Ports and mobile units (MUs). Specifically, the WS 2000 Wirel

Gateway Services Gateway Services Network Address Translation (NAT) NAT provides the translation of an Internet Protocol (IP) address within one network to a different, known IP address within another network. One network is designated the private network, while the other is the public. NAT provides a layer of security by translating local, private network addresses to one or more global, public IP addresses through a corporate firewall. The translation process provides an opportunity to

WEP 64 (40-bit key) WEP 64 (40-bit key) Wired Equivalency Privacy (WEP) uses a key, or string of case-sensitive characters, to encrypt and decrypt data packets transmitted between a mobile unit (MU) and the WS 2000 Wireless Switch. The administrator configures mobile units (MUs) and the WS 2000 Wireless Switch to use the same key. WEP encrypts the wireless transmissions, but still allows communication among compatible wireless LAN clients and MUs from third-party manufacturers that are 8

802.1x with Shared Key Authentication The pair-wise master keys (PMK) generated by this negotiation are used to generate keys used in MAC encryption. In the absence of a RADIUS server, 802.1x is used in a pre- shared key configuration. Administrators configure the master key statically through the configuration or the key is obtained through negotiation from an external RADIUS server in compliance with 802.1x. The WS 2000 Wireless Switch uses the Remote Authentication Dial-In User Service

KeyGuard-MCM Support When a Kerberos-enabled mobile unit (MU) authenticates with WS 2000 Wireless through an Access Port, the switch initially performs Kerberos authentication, even though the Kerberos server exists as a separate entity on the wired LAN. On initial request from a Kerberos-enabled MU, the WS 2000 Wireless Switch acts as a proxy to the external KDC. The switch passes initial Kerberos authentication information to the external KDC until the MU authenticates in the manner desc
