Abstract
DakNet provides extraordinarily low-cost digital communication, letting remote villages leapfrog past the expense of raditional connectivity solutions and begin development of a full coverage broadband wireless infrastructure.DakNet, an ad hoc network that uses wireless technology to provide asynchronous digital connectivity, is evidence that the marriage of wireless and asynchronous service may indeed be the beginning of a road to universal broadband connectivity.
This paper briefly explains about what is DakNet, how wireless technology implemented with DakNet, its fundamental operations and its applications, cost estimation, advantages and disadvantages and finally how to connect Indian villages with town city and global markets
Introduction
For the remote areas of the India, where even the telephone, let alone the internet, is still a distant dream,’DakNet’ brings a ray of hope. This wireless technology sends the net to villages on a local bus or even a bike in somewhat the same fashion ‘dak’ or mails are sent out. in rural areas, tele-density and connectivity is quite low, primarily because the cost of extending a fixed line from the backbone to the villages is very high and is not economically viable for the telephone companies. in an effort to bridge the digital divide between urban and rural India, the country as turned to the use of wireless technology.
In short the goal of “broadband connectivity for everyone” has been shelved in favor of cutting back to the minimum possible standard telephone service in the mistaken belief that this is the cheapest way to provide connectivity. this compromise is particularly tragic given recent advances in wireless technology, which make running a copper line to an analog telephone far more expensive than broadband wireless internet connectivity. rather than backpedal on the goal of connecting everone,society should be thinking, how can we establish the kernel of a user network that will grow seamlessly as the village’s economics develop? In other words, what is the basis for a progressive, market-driven migration from government seed services e-governance to universal broadband connectivity that local users will pay for?
What is daknet?
DakNet, whose name derives from the hindi word for “post” or “postal,” combines a physical means of transportation with wireless data transfer to extend the internet connectivity that a central uplink or hub, such as a cybercafé, VSAT system, or post office provides.
DakNet, an ad hoc network that uses wireless technology to provide asynchronous digital connectivity, is evidence that the marriage of wireless and asynchronous service may indeed be that kernel—the beginning of a road to universal broadband connectivity. Developed by MIT media lab researchers, DakNet has been successfully deployed in remote parts of both India and Cambodia at a cost two orders of magnitude less than that of traditional landline solutions. Villagers now get affordable internet services—and they’re using them. As one man in a small village outside of New Delhi remarked,” This is better than a telephone
Conclusion
DakNet’s low deployment cost and its enthusiastic reception by rural users has motivated dozens of inquires for further deployments. This should provide millions of people their first possibility for digital connectivity, and, as study after study has shown, increasing connectivity is the most reliable way to encourage economic growth. The larger goal is to shift the policy focus of the government’s universal-service-obligation funds from wire line village telephones to wireless ad hoc networking. The shift will probably require formal assessment of user satisfaction, resulting economic growth, and of course system reliability. If we can clear these bureaucratic hurdles, however, governments might be able to connect the world’s poor to the internet far sooner than anyone believed possible. And hopefully, we will be able to connect with the remote areas of the country sooner than we thought well
