Sustainable Networks and Systems for the Developing World
In this talk, I will briefly elaborate on our current efforts in addressing three broad challenges that can help in bridging the digital divide: (a) developing low-cost high-bandwidth connectivity solutions; (b) extending the Web to developing regions;(c) building new mobile applications for enhancing healthcare and financial services. This talk will specifically focus on the challenge of low-cost connectivity solutions for developing regions. I will describe our experiences in developing and deploying WiFi-based Long Distance (WiLD) Networks, a low-cost connectivity solution which provides the ability to achieve nearly 6-10 Mbps over 100s of kilometers for roughly $1000/link. WiLD networks have been deployed in 10 developing countries and have been used to provide telemedicine services in Aravind Eye hospitals in India to 50,000 patients/year in rural areas which is currently being expanded to cover 500,000 patients/year. We are currently extending WiLD networks to develop WiFi based Rural Extensions (WiRE), a low-cost alternative to cellular networks for rural settings.
