Wireless infrastructure can be varied as they provide connectivity at different levels. For instance, the personal area network or PAN is the smallest of such systems that can be created with the help of infrared or Bluetooth devices. Wireless local area networks or LANs are created when connectivity is built over a small area with the use of bridges, base stations and repeaters. The same can be created by establishing ad hoc connections between different computers. Larger networks are also created such as wireless wide area networks or WANs as well as metropolitan area networks that create connectivity across large regions in a city.
How networks are set up?
A wireless PAN is the smallest example of a wireless infrastructure setup. Such a network, usually includes different kinds of infrared and short range Bluetooth devices which are connected to each other, not requiring components like reliable managed fiber media converter. An example of a PAN is how we use Wi-Fi to connect different local devices to browse the internet. Usually there is no permanent infrastructure required when PAN is created as one can carry all necessary components with them.
Other forms of wireless networks
Homes and businesses usually have a wireless infrastructure set up with the help of different components like a POE network switch. The networks become wireless LANs and extensive hardware is used to create different kinds of connections. The simplest form of wireless LAN is the use of a wireless router. Such a network allows computer and other forms of devices to connect to each other in a localized area. Repeaters and base stations are larger infrastructure that helps create larger land area networks.
The various types of wireless infrastructure
Wireless LANs have been extended to cover a large area with the use of the radio link, microwave transmitter and laser bridge. MANs and WANs are networks where more infrastructures are required as the areas to be covered are larger. Wireless networks extend to large outdoors or can cover city areas as well. Nowadays long distance technology like WiMax is used to provide high speed access over large areas.
There are specialists who specialize in the network setup and infrastructure. Companies that need a network to be created usually need assistance of such expert service providers. Not only do you need quality work done, but security of access of data is also paramount in such cases. That is where one service provider is distinguished from another. There are several service providers in a given region that can be looked up by referring to city directories.
