    Challenges of Deploying Broadband in Rural Uganda and Smart Technical Solutions to Address these Challenges
    (School of Computing and Informatics, Makerere University, 2018) Mile, Anthony; Serumaga, Susan; Kizito, Patrick
    Since the liberalization of the telecommunication sector in Uganda in 1998, the key services have been voice, data and low rate Internet. The backbone link to the rest of the world has been via satellite which is characterized by low bandwidth limiting broadband usage in Uganda. With the arrival of undersea cables at the East African coast, Uganda is now linked to the rest of the world via optic fiber which offers high bandwidth rendering access to broadband services. Internally, wired, Optic fiber and wireless technologies such as 3G mobile and WiMAX infrastructure have brought broadband services within reach of the urban population. These improvements have revolutionized telecommunication by making broadband access more affordable and enabling converged voice, data and video/entertainment services to the urban population. Rural areas with low level or absent grid power and telecommunication infrastructure to deliver such services are still in a broadband blackout. In this paper, we discuss the challenges to rural broadband deployment in Uganda and propose possible technical solutions to address these challenges.

    IPv4 to IPv6 Transition Strategies for Enterprise Networks in Developing Countries
    (Springer, 2012) Sansa-Otim, Julianne S.; Mile, Anthony
    Internet Protocol version 4 (IPv4) addresses have been reported to be nearing exhaustion and the next generation Internet Protocol version 6 (IPv6) is gradually being deployed in the Internet. IPv6 provides a much larger address space, better address design and greater security, among other benefits. IPv6 deployment requires thorough and careful preparation to minimize network disruption and ensure that the benefits of IPv6 are obtained. The migration from IPv4 to IPv6 cannot be achieved in a short period thus the two protocols will co-exist for some time. Unfortunately, these two protocols are incompatible; hence for them to co-exist, various IPv4-to-IPv6 transition mechanisms have been developed. In this paper, we analyse the different site-to-site tunneling mechanisms through a theoretical and experimental evaluation to study their appropriateness in IPv6 deployment for enterprise networks in developing countries. Using five performance metrics, namely: endto- end delay, jitter, throughput, packet loss and CPU utilization, our experimental results indicate that Configured Tunneling performs better than the other tunneling mechanisms. This study is of importance to those enterprise networks which want to implement IPv6 and are concerned about which transition mechanisms to embrace depending on the performance requirements.
