WAN is a wide area network in which two or more computer or other devices connected to share data and resources. There are two types of medias are used for creating a comouter network i.e. Wired or Guided Media and Wirless or Unguided Media. For the connectivity of two points over a large distance we can choose any of the media on the basis of following charactersitics. 1. Wired Media- There are three types of wired medias are used for connectivity ie. Twisted, Co- axial and Fiber Optics for the long distance of connectivity we choose Fiber Optics due to it provide very high speed of data transfer. but the cost of these types of media is very expensive. If we choose Twisted Pair it has a limitation of transfer rate is maximum of 100mbps which is feasible for LAN not for the WAN. 2. Wireless Media- Wirelesss connectity can be established with the help of Wi-Fi Router, Satelite Communication, Radar etc. No doubt it provide fast transfer of data over the network but mail problem of these types of devices are first it is very expensive, second issue is with the range offered by the Wireless Access point is at limited distance so a large number of Wireless access points are required to establish a long distance based wan. Also backbone is required to be establish with wired media, which again restricted to the speed of the network.
