A communication architecture using low frequency signals

The urban and rural areas present a vast digital divide, as the urban front progresses towards faster and cheaper internet, the rural front is struggling even to make a connection. The reasons for this is more than technological, but this paper looks into one of the technical challenges identified in terms of wireless signal propagation and presents an different network architecture using low frequency signals. The traditional high frequency RF signals do not function well in dense jungle terrains and also consumes a lot of energy and therefore not ideal for this type of environment. Hence the new architecture proposed in this paper uses a new type of signal that can work efficiently in such environments and a low cost, low bandwidth. A low frequency signal is identified in the form of Sound as it is a low energy, low frequency signal with a lot of ubiquitous presence. The architecture is scalable for peer-to-peer ad-hoc mode, an infrastructure mode, a broadcast mode for remote telemetry etc. The architecture proposes using wideband multichannel transmission in order to provide some gain in throughput.
