The history of WiMAX: a complete survey of the evolution in certification and standarization for IEEE 802.16 and WiMAX

Most researchers are familiar with the technical features of WiMAX technology but the evolution that WiMAX went through, in terms of standardization and certification, is missing and unknown to most people. Knowledge of this historical process would however aid to understand how WiMAX has become the widespread technology that it is today. Furthermore, it would give insight in the steps to undertake for anyone aiming at introducing a new wireless technology on a worldwide scale. Therefore, this article presents a survey on all relevant activities that took place within three important organizations: the 802.16 Working Group of the IEEE (Institute of Electrical and Electronics Engineers) for technology development and standardization, the WiMAX Forum for product certification and the ITU (International Telecommunication Union) for international recognition. An elaborated and comprehensive overview of all those activities is given, which reveals the importance of the willingness to innovate and to continuously incorporate new ideas in the IEEE standardization process and the importance of the WiMAX Forum certification label granting process to ensure interoperability. We also emphasize the steps that were taken in cooperating with the ITU to improve the international esteem of the technology. Finally, a WiMAX trend analysis is made. We showed how industry interest has fluctuated over time and quantified the evolution in WiMAX product certification and deployments. It is shown that most interest went to the 2.5 GHz and 3.5GHz frequencies, that most deployments are in geographic regions with a lot of developing countries and that the highest people coverage is achieved in Asia Pacific. This elaborated description of all standardization and certification activities, from the very start up to now, will make the reader comprehend how past and future steps are taken in the development process of new WiMAX features

A particular attention is given to sharing millimeter-wave frequencies, which are of prominent importance for 5G

The ITU IMT-2020 Standardization: Lessons from 5G and Future Perspectives for 6G

The evaluation of candidate International Mobile Telecommunications-2020 (IMT-2020) radio interfaces ended in February 2021, with three technologies being approved while another two were granted additional time to demonstrate their suitability. This marks a useful milestone at which the International Mobile Telecommunications (IMT) standardization process can be evaluated, and its implications for 6G explored. We argue that the relationship between IMT standardization and identification is increasingly problematic, with identification requiring the refarming of spectrum already allocated to other services. Furthermore, as standardization is largely done outside of the International Telecommunication Union (ITU), being part of IMT is largely a way to obtain more spectrum. While these developments question the value of the existing approach, we argue that changes are necessary to the IMT standardization processes given the value to be gained from a single global mobile standard

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
