Wireless Mesh Networking Third Generation

Even thought the wireless technology improved everyday but it always had limitations of access points ( Nodes which allow wireless devices to connect to internet ) were limited by either restricted to buildings and houses rather than covering metropolitan areas or restricted bandwidth. There was huge need of making this wireless connectivity to give higher performance, better connectivity , larger coverage and smart wireless networking. The answer to this is given by Third Generation Wireless Mesh Networking. Welcome to another series of getting to know technology.

What is Wireless Mesh Networking (WMN) ?

Mesh is group of interconnected objects which can somehow work together if made to do so. They can act as one unit though providing possibly different types of services. Wireless Mesh Networking is group of nodes which can handle requests from different wireless devices. They act as one unit.

What is First Generation and Second Generation WMN ?

The first generation had the limitation of coverage area and high costs.It had only one node which used to handle the request as well the backhand traffic. The Second generation provided 1 + 1, or 2 radio at one node. This solved the problem of congestion as one radio used to handle the user request and other the backhand traffic. But the problem remained as they used to share the same channel, hence a slight increase in traffic could give it a hard time.

What is Third Generation WMN ?

Third Generation solutions not only solved the above problem but they had add on features that could be sued by the users.This generation of WMN added radio to each node. Hence each of them used different channel. The user request and backhand traffic was not handled by 2 different radios giving better performance and lower congestion. The first radio was responsible for up going stream and other for downloading data. This increased the bandwidth.But then Third Generation WMN was smarter. There was always a fear of breaching the network by a third party. Possibility of interference with other devices running at the same frequency. This generation used a software which can detect and avoid interference. The program continuously monitors the chances of interference and if found, changes its topology to avoid it.

Advantages of Third Generation WMN

  • Low delay
  • Minimal variation in delay.
  • Capability of supporting on demand services
  • VOIP support.
  • Suited of upcoming mobile devices like 3g and 4g devices.
