  • Page 5: Wireless Terminology

    Wireless Terminology Wireless Standards 802.11, 802.11b and 802.11g all refer to a series of standards which govern a common method of creating wireless local area networks (WLANs). 802.11b and 11g are the most common WLAN types, with 11g being the later and faster of the two standards with a maximum transmission rate of 54Mbps.
  • Page 6 WPA stands for Wi-Fi Protected Access - authorizes and identifies users based on a secret key that changes automatically at a pre-defined interval. This is called TKIP (Temporal Key Integrity Protocol) to change the temporal key every 10,000 packets (= unit of data.) Keys can either be pre-shared or established by a RADIUS Server.

  • Page 23: Appendix A: Glossary

    APPENDIX A: Glossary Access Point: An internetworking device that seamlessly connects wired and wireless networks. Ad-Hoc: An independent wireless LAN network formed by a group of computers, each with a network adapter. AP Client: One of the additional AP operating modes offered by a 54Mbps Access Point, which allows the Access Point to act as an Ethernet- to-Wireless Bridge, thus a LAN or a single computer station can join a wireless ESS network through it.
  • Page 24 Shared Key: Shared Key authentication supports authentication of stations as either a member of those who knows a shared secret key or a member of those who does not. Backbone: The core infrastructure of a network, which transports information from one central location to another where the information is unloaded into a local system.
  • Page 25 Channel: The bandwidth which wireless Radio operates is divided into several segments, which we call them “Channels”. AP and the client stations that it associated work in one of the channels. CSMA/CA: In local area networking, this is the CSMA technique that combines slotted time -division multiplexing with carrier sense multiple access/ collision detection (CSMA/CD) to avoid having collisions occur a second time.
  • Page 26 DSSS: Direct Sequence Spread Spectrum. DSSS generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission.
  • Page 27 Fragmentation: When transmitting a packet over a network medium, sometimes the packet is broken into several segments, if the size of packet exceeds that allowed by the network medium. Fragmentation Threshold: The Fragmentation Threshold defines the number of bytes used for the fragmentation boundary for directed messages.
  • Page 28 ISM Band: The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4GHz, in particular, is being made available worldwide. MAC Address: Media Access Control Address is a unique hex number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the...
  • Page 29 Preamble: The ‘preamble’ is a sequence of bits transmitted at 1Mbps that synchronises wireless transmission within the network. The Short Preamble and header may be used to minimize overhead and, thus, maximize the network data throughput. However, the Short Preamble is supported only by the IEEE 802.11b (High- Rate) standard and not by the original IEEE 802.11standard;...
  • Page 30 TCP/IP: Transmission Control Protocol/ Internet Protocol. The basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network, i.e. intranet or internet. When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.
