CS718: Wireless Networks
A wireless network is a computer network that uses wireless data connections between network nodes. Wireless communication is a way in which homes, telecommunications networks, and business installations avoid the costly process of introducing cables in a building, or as communication between various equipment areas. Administrator communication networks are generally operated and managed using radio communications. This implementation takes place at the visual level (layer) of the OSI model network structure.
Types of wireless networks
Wireless personal area networks (WPANs) connect devices to a relatively small area, usually within a person’s reach. For example, both Bluetooth radio and invisible infrared light provide a WPAN headset connected to a portable computer. ZigBee also supports WPAN applications.
Wireless LANs are commonly used to connect to local and internet services. A wireless network (WLAN) connects two or more devices over a short distance using a wireless distribution method, usually providing a network access point for internet access. The use of spread-spectrum or OFDM technology may allow users to navigate within the local coverage area, and stay connected to the network.
Wireless ad hoc network
A wireless ad network, also known as a wireless mesh network or mobile ad network (MANET), is a wireless network designed for radio nodes programmed with a mesh topology. Each node transmits messages in the name of other nodes and each node forms a route. CS718 Handouts
Metropolitan area networks are a type of wireless network that connects several wireless LANs. WiMAX is a type of Wireless MAN and is defined by the IEEE 802.16 standard. CS718 Handouts pdf download
Wide local area networks Wireless networks often cover large areas, such as between cities and neighboring cities, or city by city. These networks can be used to connect branch offices to a business or as a public Internet access system. Wireless communication between access points usually identifies microwave connectors using parabolic vessels at 2.4 GHz and 5.8 GHz bands, instead of omnidirectional antennas used with smaller networks.
A cellular network or mobile network is a radio network distributed over terrestrial areas called cells, each supplied with at least one fixed transceiver, known as a cell site or base station. In a cellular network, each cell uses a different set of radio frequencies across neighboring cells to avoid any disruption. CS718 Handouts pdf download
