“…The results obtained from the pilot showed that the solution proposed by TUCAN3G was technically and economically viable in the medium term, since the reduction of costs achieved allowed for the maintenance of the network with the income of small communities [13]. However, these studies also showed that the income obtained was not sufficient to compensate the investment required in jungle environments, therefore it was still necessary to look for subsidies to scale this type of solution to other regions and ensure sustainability in the long term.…”

“…The TUCAN3G project, funded by the European Commission, tried to fill this gap in the quest for solutions to connect the unconnected, and successfully deployed pilots of 3G cellular networks in remote areas involving an MNO [12,13]. TUCAN3G marked the guidelines for making alliances with different stakeholders that seek more sustainable and scalable rural telecommunications networks with the participation of an MNO, an experience that should be seen as complementary to the also successful experiences of bottom-up initiatives with a strong emphasis on the role of communities.…”

Rural telecommunications projects in developing regions have a long history of unsuccessful experiences due to the complexity of such projects: Practically none of the dimensions of integral sustainability are straight forward in such projects. When sustainability becomes a priority, it is difficult for traditional alliances of development to account for all critical success factors. In the Peruvian Amazon Rainforest, some institutions have developed rural telecommunications projects along the Napo River during the last 10 years. The experience has shown at each stage what aspects of sustainability were not taken into account because the partners involved did not have all the needed capacities, and this has made the alliances of partners evolve in a sustainability-driven manner. This paper analyzes these cases and assesses how sustainability has evolved in relation to the structure of such alliances.

“…Wireless networks are the preferred path investigated for finding a solution to the problem by many researchers, using ad hoc [2] or Wi-Fi based [3] networks. The economic feasibility of these solutions has also been studied by certain researchers [3] [4] [5]. Partnership-based models have generally been proposed to lower the costs of project implementation as well as make the solution affordable for consumers [4] [5].…”

Horn antennas have been observed to have excellent directive properties for transmission of microwaves. Directive communication using horn antennas can be carried out in areas with low or no network coverage through establishment of stable line-of-sight links to connect a low network coverage area to a network by using Customer Premises Equipment such as horn antennas and modems. The performances of different types of pyramidal horn antennas are therefore compared to select the best possible option among them.

“…For providing 3G and 4G connectivity, one of the most cost‐effective approaches is to use shared low‐cost private infrastructures where the operator offers services adjusted to the real needs of the target population . These infrastructures may consist of an heterogeneous wireless backhaul (BH) network that interconnects a number of small cells deployed as access networks (ANs).…”

Summary Management in wireless backhaul networks is a challenging task, especially in rural and isolated environments. In these scenarios, the backhaul network usually consists of a set of heterogeneous wireless links that provide limited and variable bandwidth to the access networks, often 3G/4G small cells. Because of the highly constrained nature of this type of backhaul network, intelligent and joint management in both the backhaul network and the access network is crucial in order to avoid performance degradation caused by traffic congestion. In order to avoid the saturation in the backhaul network, access networks should consider the backhaul state when taking decisions in the admission control and scheduling procedures. However, no standardized mechanisms currently exist for sharing management information between both networks. In this work, we propose to use the Explicit Congestion Notification (ECN) bit in the outer IP headers present in the Iuh 3GPP IPSec‐enabled interfaces in order to notify the backhaul congestion state to the access network. We analyze for the referred scenario, compatibility and security details, validating our approach by running numerically simulations and implementing the notification mechanism. Our low complexity approach offers 2% accuracy and backhaul update latency lower than 10 ms during 80% of the time, which makes the solution appropriate for admission control and scheduling intervals in small cells.
