DAK Net

DAK Net

 DAK Net is the term derived from the Hindi (an Indian Language) word DAK meaning Post which is a form of communicating a message in the form of mail. This form of communication is through a Wireless Network providing internet at a low cost to the rural areas. Even though this is not a permanent internet service, it connects the rural areas to the urban. This concept was developed by the MIT (Massachusetts Institute of Technology) alumni, also the co-founders of First Mile Solutions, Richard Fletcher and Amir Alexander Hasson.

The Ad-hoc Network in the existing communication and distribution of the relayed infrastructure of digital connectivity is provided to the villages with no such facilities. The network is the cluster of terminals (also known as the autonomous nodes) communicating with other terminals. They form a multi hop Radio connection along with maintaining the connection in a localized way. The data is transmitted point to point between the Kiosks and Portable devices with storage facilities called the Mobile Access Point (MAP).

Applications of DAK Net

The Applications of DAK Net include:

• Internet and Intranet messaging which may include uploading and downloading data (audio-video) and e-mail.
• Users can have access to mobile e-commerce applications.
• They can also have access to e-Gov applications (Apps) which are very secure and helpful.

Advantages of DAK Net

The process of connecting the villages to the urban population has created a lot of advantages to the population. They are:

• As it is a wireless service, it is easy to expand on the network coverage across the village with no cables for installation. This helps in more connectivity to the people
• It is cost effective as it uses the unlicensed part of the Radio Spectrum which bring to reduced licensing fees and regulatory challenges
• The implementation process does not require any wires or cables, there is no installation cost involved or maintenance needed
• There is a stable bandwidth provided to the customers. There is no increase or decline in the bandwidth speed
• The concept of seed infrastructure creates an easy implementation of DAK Net across the villages
• Utilizing low cost materials makes the whole process cost effective
• The connectivity works from point to point with less interference issues. This creates no loss of information

Disadvantages of DAK Net

Having provided many advantages, DAK Net provides a major disadvantage of not being a real time internet service. Apart from this there are other drawbacks which are discussed below:

• Some applications such as VOIP are not supported by the network
• The view of some of the sites such as the context customized web pages which are found on advanced sites cannot be viewed since they are unsupported
• Forms which have to be downloaded and filled from the e–commerce sites become cumbersome and problematic to use
• Asynchronous web provides no effective surfing technique
• Here the Token Ring concept is used to handle the collision. Any problems created in the lower tier will shut down the whole process
