Now one day it is very easy to establish communication from one part of the world to another. Despite this even now in remote areas villagers travel to talk to family members or to get forms that citizens in developed countries a call on a computer in a matter of seconds. The government tries to establish a telephone connection in a village in the mistaken belief that ordinary telephone is the cheapest way to provide connectivity. But recent advances in wireless technology make running a copper cable to an analog phone far more expensive than the wireless broadband connection to the Internet.
Daknet, an ad hoc network uses wireless technology to provide digital connectivity. Daknet leverages the advantages of existing transport and communications infrastructure to provide digital connectivity. Daknet whose name derives from the Hindi word "Dak" for postcard combines a physical means of transport with wireless data transfer to extend the Internet connectivity provided by an uplink, cybercafé or post office.
Real-time communications require a large capital investment and, therefore, a high level of adoption of the users to the costs of the receivers. The average villager can not even pay for a personal communications device like a telephone or a computer. To recover the cost, users must share the communication infrastructure. The real-time appearance of telephony can also be a disadvantage. Studies show that the current market for information and rural communication (ICT) services successfully does not seem to depend on real-time connectivity but on affordability and basic interactivity. The poor not only need digital services, they are willing and able to pay for them to offset the much higher costs of poor transportation, unfair prices and corruption. It is useful to consider non-real-time infrastructures and applications such as voice mail, email, and electronic bulletin boards.
Technologies such as storage and retransmission or asynchronous communication modes can have a significantly lower cost and do not necessarily sacrifice the functionality required to provide valuable user services. In addition to non-real-time applications such as e-mail and voice messaging, providers can use asynchronous communication modes to create repositories of local information that community members can add and query.
