These systems are currently being replaced by 3G wireless networks in many regions. 3G Cellular Networks. The third generation of mobile systems, currently in the process of being deployed by service carriers worldwide. These systems provide high-speed data transmissions of 144 kbps and higher and support multimedia applications such as full-motion video, video conferencing, and Internet access. 4G Cellular Networks. The fourth generation of mobile systems, these systems have not been fully defined as yet but are expected to be deployed by the end of the decade. The system is to provide high speed mobile wireless access and pervasive networks. It is to provide access through several wireless access technologies simultaneously and allow seamless connection between them. This should provide the maximum flexibility in access, network deployment and achievement of total area coverage.

  3. 802.11 Standards. The set of Wireless LAN standards set up by the IEEE to govern the creation of Wi-Fi devices for the creation of WLANs. The important standards are listed below: 802.11b – Frequency: 2.4 GHz, Maximum Bit Rate: 11 Mbps, Range: 300 feet 802.11g – Frequency: 2.4 GHz, Maximum Bit Rate: 54 Mbps, Range: 300 feet 802.11a – Frequency: 5 GHz, Maximum Bit Rate: 54 Mbps, Range: 150 feet 802.11n – Next generation Wi-Fi standard, still under development. Backbone. A trunk cable used to tie sections of a network together. Bit Rate. A measure of the rate of data transfer, the number of bits of data transferred per second, a bit is a binary digit (a 1 or 0) and is the smallest indivisible unit of data used by computers. The abbreviations bps (bits per second), Kbps (kilobits (1,000 bits) per second), Mbps (megabits (1,000,000 bits) per second), and Gbps (gigabits (1,000,000,000 bits) per second) are commonly used for this measurement. Bluetooth. A wireless networking standard for short-ranged networks, used mostly for devices such as wireless keyboards, mice and cell phones. Broadband. A high-speed connection used for wide-area networking, normally provided by T-1, Cable Modem, DSL or faster type of connection. Cable Modem. A device that enables a computer to transmit data over a cable system. It provides a bridge for converting the data for transmission between the LAN and cable network. Typically providing data transfer speeds of up to 8 Mbps for downloads and 1 Mbps for uploads. Coaxial Cable. A type of cable that contains two conductors. The center conductor is surrounded by a layer of insulation, which is then wrapped by a braided-metal conductor and an outer layer of insulation. This type of wire is usually used in cable television, VoIP phone and broadband data systems. Collocation. Location of multiple wireless communication antennae on the same wireless communications facility or support structure. Collocation of antennae is limited by the strength of the support structure, potential for interference between signals and the potential to provided signal coverage in the desired target area. Dial-up Modem. A device that enables a computer to transmit data over analog telephone lines. Typically providing data transfer speeds of up to 56 Kbps.

  4. DSL (Digital Subscriber Line). A transmission technology that allows existing copper loops in the public telephone network to be upgraded to support digital transmission of data. Typically providing data transfer speeds of up to 3.1 Mbps for downloads and 768 Kbps for uploads. Easement. A right afforded to a person to make limited use of another’s real property. Ethernet. The primary technological protocol for local area networks (LANs), synonymous with the IEEE 802.3 family of standards. The protocol ensures that most networks in the world to function in the same fashion and that they are compatible with one another through specification of software and hardware standards for computer networking. FCC (Federal Communications Commission). A U.S. government agency charged with the task of regulating all forms of interstate and international communication. The Commission has the power to regulate all electrical communications systems originating in the United States (both wired and wireless). Hotspots. A geographic location (typically within a radius of 100 meters or so) where a user can get access to Internet services by using the WLAN capabilities of the laptop (usually 802.11 b or 802.11g). HFC (Hybrid Fiber Coaxial Cable) Networks. A telecommunications network using cable in which optical fiber cable and coaxial cable constitute different portions of a network carrying broadband content (such as video, data, and voice). A local CATV company might use fiber optic cable from the cable distribution center to the serving node located near the users, and then use coaxial cable from these nodes to individual businesses and homes. An advantage of HFC is that some of the characteristics of fiber optic cable (high bandwidth and low noise /low interference susceptibility) can be brought close to the user without having to replace the entire existing coaxial cable that is installed. Hot Zones. Hotspots that cover a broad area, such as a downtown city district. Off-the-shelf radio technology such as Wi-Fi, WiMAX, and cellular 3G are usually used.

The marketing name for the IEEE 802.11 set of WLAN standards.

  8. Wireless Mesh Architecture. This is a wireless communication infrastructure between a large number of individual wireless access points (nodes). This type of infrastructure is decentralized, relatively inexpensive, and very reliable and resilient, as each node need only transmit as far as the next node. Nodes act as repeaters to transmit data from nearby nodes to peers that are too far away to reach, resulting in a network that can span large distances. Mesh networks are also extremely reliable, as each node is connected to several other nodes. WiMAX (Worldwide Interoperability for Microwave Access).
