Coverage Prediction

Communication systems depend on cell tower signals which affect the quality and efficiency of communications networks. In this paper, a prediction network coverage of 4G wireless network for operator “A” in Al Nuzhah city has been elaborated. The main objective is, firstly, to come up with prediction network maps showing the quality of communication networks in the study area and to identify areas with good and bad coverage, in order to maintain and improve coverage through relocating cell towers and antennas, increasing their number, or through installing new ones in bad coverage areas. Another objective is to compare this output with actual network coverage efficiency. In this study, GIS programs were adopted to handle, manage, process and analyze spatial and attribute data. GIS extensions were used to design communication networks such as the Mentum-Planet program through which prediction network coverage was calculated and represented. Cell towers and sectors data was first collected and then processed to generate the 4G coverage network prediction for operator "A" based on propagation model (Q9). Results were later compared to the network efficiency generated by the Drive Test. It was found that the signal strength was between -95 and -75 db. About 24.2% and 75.8% of the studied area had medium and excellent network coverage, respectively. The Drive Test showed areas of poor network coverage distributed throughout the study area. This research concluded that use of GIS in communications reduces cost and time of implementation. It is highly recommended to include building heights in the propagation model as it affects the spread of communication waves, to increase cell towers in poor coverage areas, and to modify the propagation model to ensure quality of service and efficient coverage.

The City

Experts confirm that 85% of the world’s population is expected to live in cities by 2050. Therefore, cities should be prepared to satisfy the needs of their citizens and provide the best services. The idea of a city of the future is commonly represented by the smart city, which is a more efficient system that optimizes its resources and services, through the use of monitoring and communication technology. Thus, one of the steps towards sustainability for cities around the world is to make a transition into smart cities. Here, sensors play an important role in the system, as they gather relevant information from the city, citizens, and the corresponding communication networks that transfer the information in real-time. Although the use of these sensors is diverse, their application can be categorized in six different groups: energy, health, mobility, security, water, and waste management. Based on these groups, this review presents an analysis of different sensors that are typically used in efforts toward creating smart cities. Insights about different applications and communication systems are provided, as well as the main opportunities and challenges faced when making a transition to a smart city. Ultimately, this process is not only about smart urban infrastructure, but more importantly about how these new sensing capabilities and digitization developments improve quality of life. Smarter communities are those that socialize, adapt, and invest through transparent and inclusive community engagement in these technologies based on local and regional societal needs and values. Cyber security disruptions and privacy remain chief vulnerabilities.

The scope of this work is to present a holistic approach in quality of service (QoS) and quality of experience (QoE) characterization and prediction in modern mobile communication networks. Analytically, multi radio access technologies have been deployed in order to deliver mobile services to quality demanded consumers. Quality of Experience (QoE) parameters describe the End-to-End (E2E) quality as experienced by the mobile users. These parameters are difficult to be measured and quantified. System Quality of Service (SQoS) parameters are metrics that are closely related to the network status, and defined from the viewpoint of the service provider rather than the service user. Moreover, E2E Service Quality of Service (ESQoS) parameters describe the QoS of the services and they are obtained directly from the QoE parameters by mapping them into parameters more relevant to network operators, service providers and mobile users. A useful technique for mobile network planning and optimization is to build reliable quality estimation models for mobile voice and video telephony service.

Abstract We present a short analysis of the prediction quality offered by Radio Mobile application when used for frequency band of TETRA systems in Romania. The simulation results provided by Radio Mobile were compared against own measurements made in multiple locations in Sibiu city. The correlation coefficient between simulated and measured values of signal power was of 0.907 while the maximum variation between data in the strings was 9.6 dB and the average standard deviation was 4.4 dB. These results indicate that the radio propagation model ‘Two-ray Irregular Terrain Model Point to Point’ (ITM) provides a prediction capability that offers a reliable planning of the radio coverage of TETRA systems.

Context. 5G network is able to improve existing services and provide a new quality of services. 5G communication networks combine various radio technologies and technologies of fixed communication networks, therefore they are often called heterogeneous, which emphasizes their difference from other networks. One of the main features of such networks is over-density and ultra-low latency. It is the Internet of things that is the basic component of the concept of super dense networks. 3GPP suggests planning 5G networks based on the condition that 1 million devices is 1 km2. Also, ultra-low latency communications networks have a big impact on networking methods, especially for the tactile Internet concept. Such networks require decentralization through 1 ms delay requirements. This requires new approaches to building a new generation of networks, which is the reason for the development of new technologies. One such technology is D2D (device-to-device) technology. This technology allows you to reduce the load on the core of the network due to the use of a significant proportion of the traffic directly between devices and reduces the delay in providing services. Objective. The goal of the work is to create an optimal combined criterion for choosing effective traffic routes in a wireless network based on D2D technology. Method. Many modern works are devoted to the study of D2D technology, but they are not exhaustive in the study of routing in such networks. It is objective enough to study networks built on the basis of the interaction of devices with each other using D2D technology, since such interactions have proven to be effective technologies. This, in turn, involves the development of appropriate routing methods in networks using D2D technology, especially taking into account the property of over-density 5G networks. The paper proposes a criterion for selecting routes, taking into account interference within the channels forming the network nodes. This criterion combines the choice of routes according to the length criteria and the criterion of maximum throughput. Results. A developed combined criterion for selecting traffic routing in a wireless network that uses D2D technology. The results of the study are shown in graphic data. Conclusions. The experiments confirmed the efficiency and effectiveness of the developed method and allow us to recommend this method for practical use as a result of route selection, taking into account those network properties that are more likely to affect the quality of the route.

The paper is devoted to the analysis of the known methodological support for quality assessment and control of communication services. The known approaches to quality assessment of communication services have mainly been developed in relation to the situation, characterized by the fact that each management system actually relied on its own, dedicated communication system. In this case, most of the results apply to analogue communication systems with predominantly assigned channels (paths) to certain information directions, which together reflect the structure of the control system. The synthesis of communication systems is based on the requirements of the respective control system. As a result of the analysis, the limitations of the known methodological support in the field of assessment and control of the communication services quality were revealed. In order to eliminate the identified limitations of the known methodological support in the field of assessment and control of the quality of communication services, the author has developed: analytical and simulation model of an information and telecommunication system with the required level of reliability of its elements; method for determining the parameters of the development directions of telecom operators' networks; method for assessing the probabilistic-temporal indicators of the technical resource of the fragments of the information and telecommunication system, generating communication services of a certain type.
