This study compared the CAPEX requirements for a television white space (TVWS) based broadband network and that of deploying the UMTS based mobile broadband networks to deliver broadband connectivity in areas with sparse population which characterize most of Tanzania rural. Like many developing countries, Tanzania has low Internet penetration, with penetration of just over 46% when multiple subscriptions are taken into account. The affected communities are mostly rural due to low population densities which make deployment of the mobile broadband to be much expensive in terms of costs. This limits the economic development potential in these areas given that the broadband connectivity and services is a key driver for the Fourth Industrial Revolution (4IR or Industry 4.0) and modern digital economy. Comparative between the coverage capability of the TVWS and UMTS family of standards by considering the number of base transceiver stations (BTS) is conducted to cover a specific geographic area for three different radio operating environments namely hilly, undulating and flat terrain landscapes. The broadband connectivity data rate is defined at the receiver rate of 2 Mbps or above, and used to determine the number of BTS required for the two technologies. Results show that introducing the TVWS as a middle mile solution, cuts the number of UMTS BTS required to serve the same population by 68%, 66.7%, and 75% for the three canonical environments respectively.

“…The internet penetration in Africa is still low at 30% and yet there are an escalating number of applications that rely on the internet in various fields including agriculture, education, health and governance [21]. UAVs provide a low cost solution for internet access, are suitable to provide connectivity for delivery UAVs and others that require communication with their control center and facilitate Internet of Things (IoT) as data gateways [14], [22].…”

Leveraging the Technology of Unmanned Aerial Vehicles for Developing Countries

The technology of unmanned aerial vehicles (UAVs) renders itself easily to a variety of applications because of their characteristics such as flexibility, quick deployment and cost effectiveness. Developing countries can harness UAV technology for humanitarian and development goals. This paper presents five interesting UAV applications for developing countries and these include disaster management, agriculture, delivery, surveillance of transmission lines and network coverage. UAVs aid the process of disaster management because they can be quickly deployed to take imagery which is used by rescue teams. They offer a cheap alternative to satellites and manned aircraft for agricultural mapping and management. Developing countries are faced with the major challenge of inadequate infrastructure which can be overcome by using UAVs to make especially emergency deliveries. UAVs are more effective at inspecting power transmission lines than manual techniques especially in developing countries where it is expected that the power transmission lines will span over tens of thousands of kilometres. Network coverage can be achieved cost effectively using UAVs for rural remote areas that are neglected by network operators because of their low economic return. This paper also discusses challenges that must be overcome to fully exploit UAV technology for the mentioned applications. Additionally, this paper presents interventions by African governments towards the development of UAV technology.

“…Another initiative was established by the Government of Tanzania that led to the launching of OD government portal http://opendata.go.tz/ in 2014 with the purpose of collecting and sharing data related to health, water, education and agricultural sector. Along with other initiatives, the government initiated a move to come up with OD policy that led to an OD draft policy (Igleasis, 2019; Ismail et al , 2018; The United Republic of Tanzania, 2016). However, it was noted number of these initiatives have been in draft stages for a long time.…”

Purpose This study aims to investigate the factors determining the readiness for uptake of open data (OD) in Tanzania. Specifically, this study intended to answer the question that sought to find out the factors that influence the implementation of OD in universities under study in a view to aligning with recommended strategies for optimizing the use of data in the open science era. Design/methodology/approach This study used a cross-sectional survey design whereby data were collected using quantitative and qualitative research approaches. A sample size of 212 respondents was drawn from the sampling frame of a population of 1,846 researchers from the participating universities using both probability and nonprobability sampling techniques. A self-administered questionnaire was used to collect data from researchers while interviews were administered to decision-makers. These two groups were believed to have the necessary knowledge for this study. Findings The findings indicate low or lack of skills and awareness on issues related to OD among researchers and decision-makers. This study also reveals inadequate infrastructure to support open science initiatives including OD. Moreover, this study shows a lack of supportive institutional strategies and policies that trigger the implementation of OD initiatives in Tanzania. This study recommends that universities should uplift the level of confidence of researchers by ensuring all necessary factors determining the uptake of OD are in place before and during the implementation of OD initiatives. Research limitations/implications This study was conducted during the time when researchers in universities are in an infant stage of adopting the concept from the developed world. In this regard, it is important to carry out a tracer study on establishing the OD phenomena after a number of universities have implemented OD initiatives in the country. Practical implications The researchers recommend the establishment of institutional policy and strategies to guide the implementation of OD among universities in Tanzania. Including awareness creation awareness through providing training among researchers and academics in universities. The results shed light to decision-makers on the understanding of the role of sharing research data in enhancing openness and validation of findings to increase the authenticity of results among researchers. Social implications The authors have revealed the factors affecting the implementation of OD among scholars in universities. This study reveals the level of acceptance of OD initiatives and the factors that could trigger adoption of OD. Originality/value This paper presents factors that determine the readiness for the uptake of OD in universities in Tanzania from the researcher’s perspective. This study was conducted to fill the knowledge gap that sought to establish understanding of researchers about OD. The gap was established through literature and it was found that none of the presented studies researched on this phenomenon in Tanza...
