“…The most glaring example are villages in developing countries, whose Internet connection is completely missing or significantly constrained. Accessing the Internet can greatly improve the development of these areas thanks to the enabled access to medical information and educational material [34]. Nevertheless, companies are usually not interested in deploying their communication infrastructure in these areas because the expected revenue is much lower than the actual expenditure [35].…”

One of the key features of next-generation mobile networks is the ability to satisfy the requirements coming from different verticals. For satisfying these requirements, 5G networks will need to dynamically reconfigure the deployment of the network functions. However, the current deployments of mobile networks are experiencing difficulties in exhibiting the required flexibility. At the same time, the research on connectivity provisioning in use cases such as after-disaster scenarios or battlefields has converged towards the idea of Network-In-a-Box. This idea revolves around fitting all software and hardware modules needed by a mobile network in a single or a handful of physical devices. A Network-In-a-Box inherently offers a high level of flexibility that makes it capable of providing connectivity services in a wide range of scenarios. Therefore, the Network-In-a-Box concept represents an alternative approach for satisfying the requirements of next-generation mobile networks. In this survey, we analyze the state-of-the-art of Network-In-a-Box solutions proposed by academia and industry in the time frame starting from 1998 up to early 2017. First, we present the main use cases around which the concept has been conceived. Then, we abstract the common features of the Network-In-a-Box implementations, and discuss how different proposals offer these features. We then draw our conclusions and discuss possible future research directions, including steps required to reach an even higher level of flexibility. The aim of our analysis is twofold. On one hand, we provide a comprehensive view of the idea of Network-In-a-Box. On the other hand, through the analysis we present the features that future mobile networks should exhibit to achieve their design goals. In particular, we show how the Network-In-a-Box fosters the transition towards the next-generation mobile networks.

“…To the large extent, the ability of residents in developing regions to access cell phone technology is limited by poor cellular coverage. Cellular network coverage is often a challenge in low population density and low-income areas of the developing and developed world [3]. This is attributed to the fact that major telecommunication companies hesitate to deploy expensive infrastructure in rural areas.…”

Cellular coverage is often a challenge in low population density and low income rural areas of the developing world like Tanzania. This is because big Telecom companies defer from deploying their expensive infrastructure in these areas fearing operations cost. It is proposed that the use of cellular open source technology as the basis for a new rural cellular network can go a long way in meeting this challenge by providing coverage in rural areas whilst simultaneously bringing down the cost of communication. This paper provides survey of recent open source cellular technologies. It further presents a prototype based on Open BTS for cellular connectivity in developing countries. In lab performance test for the proposed prototype confirm the feasibility of deploying cellular network based on open source technologies as an alternative to conventional mobile operator networks in a bid to solve the challenge.

Wireless localization has been an active research area over the last decade due to its endless applications. In this paper, we investigate received signal strength (RSS) based estimation of a mobile station's location, through monitoring the RSS at multiple reference software defined radio (SDR) receivers. Uplink transmission power of the mobile stations and path loss exponent are assumed to be unknown parameters. Universal software radio peripheral (USRP) devices are used to capture the RSS from uplink transmission of a mobile user. Subsequently, a linear least square localization technique is used to obtain the location estimate of the mobile station. Experiments with real mobile phones are conducted to demonstrate achievable localization accuracies in indoor environments with GSM technology.
