An Abbreviated Wireless Dictionary Access Point - A device that transports data between a wired network (infrastructure) and a wireless network. Typically, the term "access point" is used to describe one of many such devices that provide wireless network access over a large space (office building, warehouse, etc.) where distances exceed the range of a single wireless network source. Broadband - The broadband communication network has significantly greater bandwidth than telephone networks. Cable Modem - Cable modems are connected to Cable TV providers who offer Internet access. A cable modem connects users to the Internet through a coaxial connection. Cable technology allows for transfer rates up to 30Mbps, however, bandwidth through a cable connection is shared among all subscribers in a defined area, or neighborhood. Actual transfer rates vary from 265Kbps to 4Mbps depending on a variety of factors. Cat-5 Cable - Short for Category 5. Cat-5 cables allow the transfer of data at high speeds and are commonly used to connect computers to a local area network (LAN). Made up of four twisted copper wires, a Cat-5 cable can support frequencies up to 100 MHz and data speeds up to 100 Mbps. Cat-5e Cable - Short for Category 5 enhanced. Cat-5e cable is becoming quite common in new network installations. Cat-5e is capable of transferring data at higher rates than Cat-5, which may an advantage for future upgrades. ISP - Short for Internet Service Provider, an ISP is a company that provides individuals and companies access to the Internet to surf the World Wide Web and send and receive e-mail. An Internet Service Provider is required to connect to the Internet using wireless technology. DSL - Digital Subscriber Line is a technology that allows the transmission of information over a traditional telephone line. Data transfer rates are considerably higher than with dial-up modems. 802.11 - The standard that is used to define how wireless networking is implemented. The 802.11 standard is administered by the Institute of Electrical and Electronics Engineers (IEEE). 802.11 has several "flavors", three of which may be of interest; 802.11a, 802.11b, and 802.11g. 802.11a - Fast, but not commonly employed. 802.11a is wireless LAN specification that provides up to 54 Mbps connection speed at 5 GHz. The higher operating frequency means a shorter transmission range (about 60 feet). 802.11a equipment is not interoperable with 802.11b or 802.11g equipment. 802.11b - Very commonly employed. Also referred to as Wireless Fidelity (Wi-Fi), 802.11b allows wireless data transfer of up to 11 Mbps. The transmission range of 802.11b is up to 300 feet.
802.11g - Because 802.11g is usually compatible with 802.11b, it is becoming popular. 802.11g can transfer up to five times more data than its predecessor (54 Mbps compared to 11 Mbps). The transmission range of 802.11g is generally about 10 percent short of 802.11b. Network Adapter - see NIC. LAN - Local Area Network is a series of interconnected computers that can share resources, peripherals, and access to the Internet. NIC - Network Interface Card. The term NIC (pronounced "nick") can be used interchangably with the term "network adapter". A NIC allows a computer to communicate with a network. Each computer on a network must have a NIC. NICs are typically either wired or wireless, but usually not both. Types of NICs: Mini-PCI NIC - an internal NIC found in notebook computers. PC Card NIC - (also known as a PCMCIA card NIC) - an external device for portable computers about the size of a credit card. The PC Card NIC fits into slots located on sides of many notebook computers. USB NIC - an external NIC that can be used with either a USBequipped desktop computer or a USB-equipped portable computer. PCI NIC - an internal NIC installed in a desktop computer. WEP Encryption - Wired Equivalent Privacy is a security protocol for wireless LANs defined by the 802.11b standard. WEP is designed to provide the same level of security as that of a wired LAN. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. Wireless Router - A wireless router is an 802.11b, g, or a wireless access point with a built in Internet router. With a connection to a cable or DSL modem, many wireless routers can provide simultaneous access to the Internet for both wired and wireless computers. A network requires the following components: An Operating System capable of networking (such as Windows®) Network Client Software (Microsoft, Novell) Cabling if wired Network client card (NIC, LOM) Drivers for client cards Network Protocol (TCP/IP, IPX/SPX, NetBEUI) - one for each computer Return to Table of Contents
What Is a Wireless Network? A Wireless Local Area Network (WLAN) is a series of interconnected PCs that communicate over the air waves as if they were connected with wires. In a Wireless Local Area Network, a radio communications device called an access point or wireless router connects network computers and provides Internet or network access. The access point or wireless router is small and lightweight with an antenna attached to it that sends data back and forth over the air waves. Return to Table of Contents

An Abbreviated Wireless Dictionary Access Point - A device that transports data between a wired network (infrastructure) and a wireless network. Typically, the term "access point" is used to describe one of many such devices that provide wireless network access over a large space (office building, warehouse, etc.) where distances exceed the range of a single wireless network source. Broadband - The broadband communication network has significantly greater bandwidth than telephone networks. Cable Modem - Cable modems are connected to Cable TV providers who offer Internet access. A cable modem connects users to the Internet through a coaxial connection. Cable technology allows for transfer rates up to 30Mbps, however, bandwidth through a cable connection is shared among all subscribers in a defined area, or neighborhood. Actual transfer rates vary from 265Kbps to 4Mbps depending on a variety of factors. Cat-5 Cable - Short for Category 5. Cat-5 cables allow the transfer of data at high speeds and are commonly used to connect computers to a local area network (LAN). Made up of four twisted copper wires, a Cat-5 cable can support frequencies up to 100 MHz and data speeds up to 100 Mbps. Cat-5e Cable - Short for Category 5 enhanced. Cat-5e cable is becoming quite common in new network installations. Cat-5e is capable of transferring data at higher rates than Cat-5, which may an advantage for future upgrades. ISP - Short for Internet Service Provider, an ISP is a company that provides individuals and companies access to the Internet to surf the World Wide Web and send and receive e-mail. An Internet Service Provider is required to connect to the Internet using wireless technology. DSL - Digital Subscriber Line is a technology that allows the transmission of information over a traditional telephone line. Data transfer rates are considerably higher than with dial-up modems. 802.11 - The standard that is used to define how wireless networking is implemented. The 802.11 standard is administered by the Institute of Electrical and Electronics Engineers (IEEE). 802.11 has several "flavors", three of which may be of interest; 802.11a, 802.11b, and 802.11g. 802.11a - Fast, but not commonly employed. 802.11a is wireless LAN specification that provides up to 54 Mbps connection speed at 5 GHz. The higher operating frequency means a shorter transmission range (about 60 feet). 802.11a equipment is not interoperable with 802.11b or 802.11g equipment. 802.11b - Very commonly employed. Also referred to as Wireless Fidelity (Wi-Fi), 802.11b allows wireless data transfer of up to 11 Mbps. The transmission range of 802.11b is up to 300 feet.
802.11g - Because 802.11g is usually compatible with 802.11b, it is becoming popular. 802.11g can transfer up to five times more data than its predecessor (54 Mbps compared to 11 Mbps). The transmission range of 802.11g is generally about 10 percent short of 802.11b. Network Adapter - see NIC. LAN - Local Area Network is a series of interconnected computers that can share resources, peripherals, and access to the Internet. NIC - Network Interface Card. The term NIC (pronounced "nick") can be used interchangably with the term "network adapter". A NIC allows a computer to communicate with a network. Each computer on a network must have a NIC. NICs are typically either wired or wireless, but usually not both. Types of NICs: Mini-PCI NIC - an internal NIC found in notebook computers. PC Card NIC - (also known as a PCMCIA card NIC) - an external device for portable computers about the size of a credit card. The PC Card NIC fits into slots located on sides of many notebook computers. USB NIC - an external NIC that can be used with either a USBequipped desktop computer or a USB-equipped portable computer. PCI NIC - an internal NIC installed in a desktop computer. WEP Encryption - Wired Equivalent Privacy is a security protocol for wireless LANs defined by the 802.11b standard. WEP is designed to provide the same level of security as that of a wired LAN. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. Wireless Router - A wireless router is an 802.11b, g, or a wireless access point with a built in Internet router. With a connection to a cable or DSL modem, many wireless routers can provide simultaneous access to the Internet for both wired and wireless computers. A network requires the following components: An Operating System capable of networking (such as Windows®) Network Client Software (Microsoft, Novell) Cabling if wired Network client card (NIC, LOM) Drivers for client cards Network Protocol (TCP/IP, IPX/SPX, NetBEUI) - one for each computer Return to Table of Contents
