Advantages of Wireless WAN

A wide area network (WAN) is a communication network that consists of computers for exchanging data across a wide area. A WAN is formed by linking LANs together. The Internet is the biggest WAN.

Wireless WAN services offer some significant advantages. That includes:
  • No wires: with the 4G services available, there is any need to wait for wired services to get the connection because they offer high bandwidth. In many underdeveloped regions, wireless services offer the potential to bring high speed access, but in developed countries like USA and UK the 4G services are available.
  • Lower cost: Wireless WAN services are billed on a base monthly fee plus usage rate, making them suitable as an on-demand backup service versus an always-on connection where pricing isn't tied to usage.
  • Low latency: Emerging wireless WAN services are suitable for voice and video, enabling wireless WANs to support the full spectrum of enterprise IP based applications.
  • Mobility: Wireless WAN services are useful for temporary locations such as field offices, clinical trial locations, or construction sites. There are many differences between wires and wireless WAN but the key among them are ability to quickly get up and run, and quickly move to the next location.

Though there are many advantages of wireless WAN, non-availability of the wireless WAN is found to be a major problem. 4G wireless technologies are not available in outside major metropolitan areas in developed countries like the U.S. and Europe. Though 3G services may be useful for small offices consisting of less number of employees, they have limited bandwidth and they are less suited to latency-sensitive applications such as voice.
