Samvidha

Providing low cost internet access from rural
schools



Rural schools have only noisy phone lines
Most cannot afford the cost of long connections
Offline access


Student queries packed by local server in school
and sent in email to central server
Central server browses web to get results,
packages pages and sends to local server. Can be
accessed anytime after that
