The work behind this paper aims at demonstrat-ing innovative solutions for the establishment of sustainablecommunity broadband networks in areas where there is de-mand but no supply of broadband services. One of the majorchallenges turns out to be reliable power supply. To overcomethis challenge, we explore how to decrease the demand forpower as well as the feasibility of using alternative powersources, such as solar and wind, and alternative power storagetechnologies, such as batteries and ultra-capacitors.In this paper, we present data collected over 2 months fromthe Serengeti community network in rural Tanzania to discussthe quality of the existing power-grid and the feasibility ofusing solar and wind energy as alternative energy sources.The network backbone is based on 1Gbps Ethernet links overdark fibre while end-user connections are currently based onWiFi links.Our measurements regarding the quality of the power-gridshow up to 21 power-outages in one single day, with an averageof 2 outages per day. Some of the outages are due to plannedrationing schemes caused by insufficient power generationwhile some outages are due to poor wiring or installations.Our measurements and analysis of the feasibility of usingalternative power sources indicate wind speeds on the average2m/s and a persistent high-level insolation, making solar energythe prime candidate as an alternative source of electricity. Therelatively high cost of solar panels has to be mitigated byincreased energy efficiency of the network elements. We alsopropose power management to be included in the networkmanagement system to maximize the availability of the net-work services and decrease operational costs due to damagednetwork elements.
