Wireless Technology Overview
Wireless network technology is becoming increasingly popular for a wide variety of applications. After evaluating the technology, most users are convinced of its reliability, satisfied with its performance and are ready to use it for large-scale and complex wireless networks. 
Originally designed for indoor office applications, today's wireless networks can be used for both indoor Ethernet networks as well as for outdoor point-to-point and point-to-multipoint remote bridging applications. Wireless networks can be designed to be modular and flexible to meet temporary conditions or optimized for harsh weather conditions and environments.


Wired Network Topology
Traditional networks link PCs and other computers to one another and to file servers, printers and other network equipment using cables or optical fiber as the transmission medium. 




Wireless Network Topology
Wireless networks allow workstations to communicate and to access the network using radio propagation as the transmission medium. The wireless network can be connected to an existing wired network as an extension, or can form the basis of a new network. While adaptable to both indoor and outdoor environments, wireless networks are especially suited to indoor locations such as office buildings, manufacturing floors, hospitals, and schools or universities. 
The basic building block of the wireless network is the cell. This is the area in which the wireless communication takes place. The coverage area of a cell depends on the strength of the propagated radio signal, as well as the type and construction of walls, partitions, and the other physical characteristics of the indoor environment. PC-based workstations, notebook computers, and pen-based computers can move freely within the cell. Each Wireless cell requires some communications and traffic management. This is coordinated by an Access Point (AP), which communicates with each wireless client in its coverage area. Clients also communicate with each other via the AP, so communicating clients can be hidden from one another. In this way, the AP functions as a relay, extending the range of the system. The AP also functions as a bridge between the wireless clients and the wired network, as well as the other wireless cells. Connecting the AP to the wired backbone or other wireless cells can be done by wire or by a separate wireless link, using wireless bridges. The range of the system can be extended by cascading multiple wireless links, or by creating a wireless backbone or infrastructure utilizing other radio frequencies so as not to interfere with the cell frequencies. 


Wireless Connectivity Roaming
When any area in the building is within reception range of more than one Access Point (AP), the cells' coverage is said to overlap. Each wireless client automatically establishes the best possible connection with one of the APs. Overlapping coverage areas are an important attribute of the wireless network setup, because it enables seamless roaming between overlapping cells. Roaming allows mobile users with portable clients to move freely between overlapping cells, constantly maintaining their network connection. Roaming is seamless - a work session can be maintained while moving from one cell to another. Multiple APs can provide wireless coverage for an entire building or campus. When the coverage area of two or more APs overlap, the clients in the overlapping area can establish the best possible connection with one of the APs, continuously searching for the best AP.
