  Rural connectivity is widely research topic for several years. In India,
around 70% of the population have poor or no connectivity to access digital
services. Different solutions are being tested and trialled around the world,
especially in India. They key driving factor for reducing digital divide is
exploring different solutions both technologically and economically to lower
the cost for the network deployments and improving service adoption rate. In
this survey, we aim to study the rural connectivity use-cases, state of art
projects and initiatives, challenges, and technologies to improve digital
connectivity in rural parts of India. The strengths and weakness of different
technologies which are being tested for rural connectivity is analyzed. We also
explore the rural use-case of 6G communication system which would be suitable
for rural Indian scenario.
