AirJaldi networks: Wireless Mesh Network in India
About Air Jaldi
The Air Jaldi (The dharamsala community wireless mesh project) came in direct response to international interest in the Dharamsala Community Wireless Mesh Network. It was developed in cooperation with the Dharamsala Information Technology Group, an organization chaired by the Tibetan Computer Resource Center and some of the region‘s leading information technology professionals. The Mesh backbone includes over 30 nodes, all sharing a single radio channel. Broadband Internet services are provided to all mesh members. The total upstream Internet bandwidth available is 6Mbps. There are over 2000 computers connected to the Mesh, and about 500 have Internet accessThe dhramshala wireless mesh project has: Exceptional affordability, performance and features. Suitability for rural settings and communities. Modular design which enables expansion in line with needs and demand
Air jaldi led to a wireless mesh area network in and around dharamsala which: Interconnects thousands of computers within difficult mountain terrain covering a radius of around 50 km. Provide broadband internet access, VOIP telephony, file sharing, offsite backup and video based application. By integrating multiple existing open-source software projects, with a little on-site tuning the team managed to build one of Asia's largest wireless mesh networks
About Wireless Mesh Networks
Wireless mesh network (WMN) consists of mesh points and wireless mesh backbone of routers providing services to various heterogeneous users. The WMN is a rapidly evolving technology and is gaining popularity as a alternate solution to Ethernet and other wireless protocols.
Mesh networks are different – full physical layer connectivity is not required. As long as a node is connected to at least one other node in a mesh network, it will have full connectivity to the entire network because each mesh node forwards packets to other nodes in the network as required. Mesh protocols automatically determine the best route through the network and can dynamically reconfigure the network if a link becomes unusable.WLAN Coverage
The first wireless mesh networks were mobile ad hoc networks – with wireless stations moving around and participating in a peer to peer network. Mesh is an attractive approach for wireless networking since wireless nodes may be mobile and it is common for a wireless node to participate in a network without being able to hear all of the other nodes in the network.
