PCI-G31 WLAN Card User Manual 7. Glossary Access Point (AP) A networking device that seamlessly connects wired and wireless networks. Access Points combined with a distributed system support the creation of multiple radio cells that enable roaming throughout a facility. Ad Hoc A wireless network composed solely of stations within mutual communication range of each other (no Access Point). Basic Rate Set This option allows you to specify the data transmission rate.
PCI-G31 WLAN Card User Manual COFDM (for 802.11a or 802.11g) Signal power alone is not enough to maintain 802.11b-like distances in an 802.11a/g environment. To compensate, a new physical-layer encoding technology was designed that departs from the traditional direct-sequence technology being deployed today. This technology is called COFDM (coded OFDM). COFDM was developed specifically for indoor wireless use and offers performance much superior to that of spread-spectrum solutions.
PCI-G31 WLAN Card User Manual DNS Server Address (Domain Name System) DNS allows Internet host computers to have a domain name and one or more IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a user enters a domain name into the Internet browser, the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned.
PCI-G31 WLAN Card User Manual Encryption This provides wireless data transmissions with a level of security. This option allows you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters. 64-bit and 40-bit WEP keys use the same encryption method and can interoperate on wireless networks.
PCI-G31 WLAN Card User Manual ICS ICS is used to share one computer’s Internet connection with the rest of the computers on your network. When this computer is connected to the Internet, all the communications to and from the Internet on your network are sent through this computer which is called the host computer. The rest of the computers can send and receive e-mail messages and access the web as if it were connected directly to the Internet. IEEE The Institute of Electrical and Electronics Engineers.
PCI-G31 WLAN Card User Manual The 802.11a standard gains some of its performance from the higher frequencies at which it operates. The laws of information theory tie frequency, radiated power and distance together in an inverse relationship. Thus, moving up to the 5GHz spectrum from 2.4GHz will lead to shorter distances, given the same radiated power and encoding scheme. Compared with 802.11g: 802.11a is a standard for access points and radio NICs that is ahead of 802.
PCI-G31 WLAN Card User Manual IP (Internet Protocol) The TCP/IP standard protocol that defines the IP datagram as the unit of information passed across an Internet and provides the basis for connectionless packet delivery service. IP includes the ICMP control and error message protocol as an integral part. It provides the functional equivalent of ISO OSI Network Services. IP Address An IP address is a 32-bit number that identifies each sender or receiver of information that is sent across the Internet.
PCI-G31 WLAN Card User Manual NIC (Network Interface Card) A network adapter inserted into a computer so that the computer can be connected to a network. It is responsible for converting data from stored in the computer to the form transmitted or received. Packet A basic message unit for communication across a network. A packet usually includes routing information, data, and sometimes error detection information.
PCI-G31 WLAN Card User Manual Radio Frequency (RF) Terms: GHz, MHz, Hz The international unit for measuring frequency is Hertz (Hz), equivalent to the older unit of cycles per second. One megahertz (MHz) is one million Hertz. One gigahertz (GHz) is one billion Hertz. The standard US electrical power frequency is 60Hz, the AM broadcast radio frequency band is 0.55-1.6MHz, the FM broadcast radio frequency band is 88-108MHz, and wireless 802.11 LANs operate at 2.4GHz.
PCI-G31 WLAN Card User Manual WPA (Wi-Fi Protected Access) Wi-Fi Protected Access (WPA) is an improved security system for 802.11. It is part of the 802.11i draft security standard. WPA encompasses TKIP (Temporal Key Integrity Protocol) along with MIC (Message Integrity Check) and other fixes to WEP such as Weak IV (Initialization Vector) filtering and Random IV generation. TKIP uses 802.1x to deploy and change temporary keys as opposed to static WEP keys once used in the past.
