Impact of regulatory aspects on 5G mobile communication systems

The fifth generation of mobile communication networks generally known as 5G is a technology that, if we read anything about it we can arrive to the conclusion that it can be a revolution in many aspects. Starting with the great change that the telephone introduced, followed by the great improvements that the mobile phones carried along with them and finally internet and broadband access from any part of the world with a pocket device, we arrive to a time where 5G not only will it improve the existing technologies but it will allow the development of new inventions such as Internet of Things (IoT) that up to the date is reduced to various experiments and trials. The fifth generation of mobile communication systems will allow the development of applications, data models, data analysis at very high speeds, sensor measurements, and data transmissions instantly and a very long list of other things that will result in a revolution in one hand for the people’s lives and in the other to the markets and the way the companies carry out their business models and their internal and external general management. People’s quality of life will be affected substantially thanks to the establishment of 5G. This will be achieved thanks to the high speeds and the characteristics that 5G includes, and it will allow, for example, that a refrigerator can inform its owner about what products are needed or about what food is about to expire. This simple example is only one of many others that we can find when talking about 5G. Nonetheless, in order to be able to enjoy these advantages that 5G incorporates, it is necessary to conduct a development and deployment in an agreed upon way between all the different organisms and bearing in mind the regulatory aspects and the legislation valid and that needs to be developed in order to have a correct deployment. To do this, the regulatory organisms, and the commissions of the different countries have to agree between them and investigate what is the best way to provide the best standards, and to ease and speed up the deployments and start-ups of this new technology. After developing a detail study of the current requirements, objectives and the legislation and standardization, as well as the state of art of the technologies that provide us with the services that we enjoy nowadays, I have studied the barriers and drivers for the deployment of 5G. Finally, and after this previous study, I have analysed the possible deployments for this technology and how will it affect to the economic and social environment the use of these types of mobile communications. At the same time I have arrived to the final conclusions that 5G will be a complete revolution and anything that enables and eases the implementation has to be welcome.La quinta generación de redes de telecomunicaciones móviles comúnmente conocida como 5G es una tecnología de la que, si leemos cualquier información, llegaremos a la conclusión de que puede suponer una revolución en muchos aspectos. Comenzando por el gran cambio que supuso la invención del teléfono, seguida por la evidente y alta mejora que introdujo el teléfono móvil y finalmente la conexión a internet y el acceso de banda ancha desde cualquier parte del mundo con un dispositivo de bolsillo, llegamos a un momento en el que el 5G no solo mejorará las tecnologías ya existentes sino que permitirá desarrollar ideas tales como el internet de las cosas que, a día de hoy, se reducen a, varios experimentos y pruebas. El 5G permitirá el desarrollo de aplicaciones, modelos de datos, análisis de datos a altas velocidades, lecturas de sensores y transmisión de datos de forma instantánea y una larga lista de mejoras más que resultará en una revolución por una parte de la vida de las personas y por otra de los mercados y de la forma en la que las empresas llevarán a cabo sus modelos de negocio y en general su gestión externa e interna. La calidad de vida de las personas se verá afectada de forma sustancial gracias a la implantación del 5G. Esto se conseguirá debido a que las altas velocidades y las características que incorpora el 5G permitirán que, por ejemplo, una nevera avise a su dueño de aquello que falte en su interior, o que le informe de aquellos productos que están a punto de caducar. Este simple ejemplo solo es uno de todos los posibles que se pueden encontrar a la hora de hablar del 5G. Sin embargo, para poder llegar a disfrutar de todas las ventajas que el 5G aporta, es necesario llevar a cabo un desarrollo y un despliegue de forma conjunta entre los diferentes organismos, y teniendo en cuenta la normativa y legislación vigente y que se necesita desarrollar, para que este despliegue sea correcto. Para ello, los organismos regulatorios y las comisiones de diferentes países, deben ponerse de acuerdo e investigar cuál será la mejor forma de proporcionar los mejores estándares y facilitar y acelerar los despliegues y puestas en marcha de esta nueva tecnología. Después de llevar a cabo un estudio detallado sobre los requisitos, objetivos y la normativa y estandarización actual, así como el estado del arte de las tecnologías que hoy nos proporcionan los servicios de los que disfrutamos, se han estudiado las barreras y los aspectos favorecedores para la implantación del 5G. Finalmente, y tras este previo estudio, se han detallado los posibles despliegues para esta tecnología y se ha estudiado como afectará al entorno económico y social la utilización de este tipo de redes de comunicaciones móviles. A su vez, se han llegado a las conclusiones finales de que el 5G supondrá toda una revolución, y que todo aquello que favorezca su despliegue e implantación, debe ser bienvenido.Ingeniería Telemátic

High Directive Wideband Microstrip Patch Antenna for 5G Mobile Phone Application

A compact micro strip patch antenna has been investigated for 5G mobile application. The antenna is especially designed for 5G mobile communication. The antenna is excited by inset feeding technique. The antenna resonates at 38.256 GHz. Proposed patch configuration shows improved bandwidth of 10 GHz with the offset transmission line feed. The antenna was fabricated using a single FR4 substrate of dimension 2.69×4.55×1.6 mm3

A Study on the Effect of Quality Factors of Smartphone 5G Technology on the Reliability of Information and Communication Policy

This paper analyzes the effect of the characteristics of 5G services on users\u27 continuous intention to use, focusing on the technology acceptance model. With the start of the fourth industrial revolution in the 21st century, 5G is the best technology used in the Internet of Things, high-speed information and communication, artificial intelligence, big data, autonomous vehicles, virtual reality, augmented reality, robots, nanotechnology, and blockchain. The technical characteristics of 5G ultra-high-speed information communication are represented by ultra-high speed, ultra-high capacity, ultra-low delay, and ultra-high connectivity. 5G mobile communication technology is essential, and after the technology provided by 5G services is commercialized, it can play all its roles as a practical core new growth engine. 5G mobile communication (hereinafter referred to as 5G) is far superior to LTE, which is a 4G mobile communication, in terms of transmission speed, waiting time, and terminal capacity. 5G service is not just an axis of the process of developing mobile communication technology, but also the creation of innovative corporate value of technology. This is because higher network quality and innovation with 5G service technology will improve perceived usability, perceived ease of use, and perceived entertainment, which will ultimately have a positive impact on users\u27 intention to use 5G services. Therefore, due to the lack of investment in information and communication bases, platforms, and applications, this paper can be used as the basis for establishing government policies

Performance Analysis of Microstrip Grid Array Antenna on Different Substrates for 5G Mobile Communication

This paper investigated the performance and characteristics of microstrip grid array antenna (MGAA) on three different substrates which are Rogers RT5880LZ, Taconic RF-43, and Fr-4. For this work, the proposed MGAA has been designed at 15 GHz for 5G mobile communication application. The proposed microstrip grid array antenna consists of 12 cells block with 19 radiating elements and was feed using the 50 Ω coaxial port from the ground plane. A comprehensive study on the effect of substrate on the performance of MGAA is carried out. S-parameters, gain, and efficiency of MGAA on all those substrates have been used as parameters in determining the performance of proposed antenna in order to fulfill the design criteria for 5G mobile communication application. The design and simulation process of MGAA was done in CST Microwave Studio Softwar
