Verify that the “channel” of the WLAN Adapter is “Auto” or set to the same “channel” of the other station (or another WLAN Adapter). d.
Chapter 5 - Glossary 5. 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.
Chapter 5 - Glossary Each subchannel in the COFDM implementation is about 300 KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125 Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps, data rate. Using quadrature phase shift keying, you can double the amount of data encoded to 250 Kbps per channel, yielding a 12-Mbps data rate. And by using 16-level quadrature amplitude modulation encoding 4 bits per hertz, you can achieve a data rate of 24 Mbps.
Chapter 5 - Glossary Direct-sequence systems communicate by continuously transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the output signal.
Chapter 5 - Glossary Ethernet The most widely used LAN access method, which is defined by the IEEE 802.3 standard. Ethernet is normally a shared media LAN meaning all devices on the network segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10-BaseT cables. Firewall A firewall determines which information passes in and out of a network. NAT can create a natural firewall by hiding a local network’s IP addresses from the Internet.
Chapter 5 - Glossary The 802.11b spectrum is plagued by saturation from wireless phones, microwave ovens and other emerging wireless technologies, such as Bluetooth. In contrast, 802.11a spectrum is relatively free of interference. 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 5-GHz spectrum from 2.
Chapter 5 - Glossary 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.
Chapter 5 - Glossary Packet A basic message unit for communication across a network. A packet usually includes routing information, data, and sometimes error detection information. Passphrase The Wireless Settings utility uses an algorithm to generate four WEP keys based on the typed combination. PPP (Point-to-Point Protocol) PPP is a protocol for communication between computers using a serial interface, typically a personal computer connected by phone line to a server.
Chapter 5 - Glossary TCP (Transmission Control Protocol) The standard transport level protocol that provides the full duplex, stream service on which many application protocols depend. TCP allows a process or one machine to send a stream of data to a process on another. Software implementing TCP usually resides in the operating system and uses the IP to transmit information across the network. WAN (Wide Area Network) A system of LANs, connected together.
