Insights into sustainable energy-capacity trends towards bridging the digital divide a perspective of the need for green broadband communications in Sub Saharan Africa

This paper presents an analysis of energy-capacity trends of the broadband communications services in Sub Saharan Africa sampling Sudan case. The analysis utilizes the joule/bit metric to visualize the distribution of the broadband services availability across the country, hence the region. Consequently this provides an explanation for how the energy-capacity relationship can impact the Digital Divide. The socio economic aspects and policy impacts of this phenomenon are analyzed. We further present steps towards implementing greener solutions to the digital divide via the introduction of Hybrid Wireless-fiber Broadband access systems that combine Passive Optical Networks (PON) with Self-organizing wireless Networks based on Wimax and LTE systems.
