The primary need for mass e-health service is, the remote doctor should be able to examine the patient through video communication over public Information and Communication Technology (ICT) infrastructure. However, poor ICT infrastructure creates a key obstacle for rural India due to low bandwidth and intermittent Internet connectivity. This paper critically examines the state of the public ICT infrastructure in India and proposes an end-to-end solution such that the Quality of Experience (QoE) for remote visual examination can be ensured over IP connectivity even in a 2G network. We extend previously proposed video streaming solution for Internet of Things (IoT) called A-REaLiST (Adaptive-RESTful Real time Streaming for Things). Thus we extend the design principles of IoT communication in order to achieve an acceptable QoE by effectively harnessing the latent potential in the existing infrastructure. Efficacy of the solution is determined through benchmarking experiments under realistic network conditions and comparing with existing state of the art.
