<P> Products using the IEEE 802.11 WLAN standards are marketed under the Wi - Fi brand name . Fixed wireless technology implements point - to - point links between computers or networks at two distant locations, often using dedicated microwave or modulated laser light beams over line of sight paths . It is often used in cities to connect networks in two or more buildings without installing a wired link . </P> <P> A wireless ad hoc network, also known as a wireless mesh network or mobile ad hoc network (MANET), is a wireless network made up of radio nodes organized in a mesh topology . Each node forwards messages on behalf of the other nodes and each node performs routing . Ad hoc networks can "self - heal", automatically re-routing around a node that has lost power . Various network layer protocols are needed to realize ad hoc mobile networks, such as Distance Sequenced Distance Vector routing, Associativity - Based Routing, Ad hoc on - demand Distance Vector routing, and Dynamic source routing . </P> <P> Wireless metropolitan area networks are a type of wireless network that connects several wireless LANs . </P> <Ul> <Li> WiMAX is a type of Wireless MAN and is described by the IEEE 802.16 standard . </Li> </Ul>
