This subject aims to provide a broad view and, above all, one focused on the business perspective of broadband networks mainly used by telecommunications operators. A brief introduction to the course is given, the different transmission networks are explained, both terrestrial and satellite, switching networks with Quality of Service (QoS) are explained, access networks, advanced services, the platforms available on the market are explained, and finally the interconnections between telecommunications operators are taught.
The subject New Generation Broadband Networks presents the latest advances and trends in the telecommunications sector, from a technological perspective. It encompasses the most important parts of operators' networks: transmission, switching, access, intelligent network and interconnection network between operators.
The approach of the course is the teaching of knowledge based on real practical examples of currently existing networks and their trends.
Titular Professors
It is recommended to have taken and passed Local Area Networks (49063 / 49A63) and Interconnection of Data Networks (GI003 / GIA03). It may also be beneficial to be taking or to have taken Computer Network Technologies (TL003) and Networking Laboratory (TL002).
The course aims to provide the student with a solid and applied view of next-generation broadband networks in the field of telecommunications operators, developing the ability to understand the main technologies, architectures and operating criteria involved in transmission, switching, access and interconnection networks. Likewise, it aims to promote the analysis of real technological solutions, the understanding of the role of Quality of Service in these environments, and the application of basic network planning criteria, contributing to the development of relevant technical competences for professional practice in the field of networks and Internet technologies.
The syllabus of the course is as follows:
1. INTRODUCTION

2. TRANSMISSION NETWORK
- WDM technology
- Components of the optical layer
- Optimised networks
- Satellite communications
3. SWITCHING NETWORK

- Submarine cable infrastructure
The methodology used in this course is based on:
- Lectures in class, where the lecturer teaches the theoretical concepts of the course throughout the semester.
- Problem-solving lessons, where exercises related to the theoretical content explained in each topic are solved and new exercises are proposed so that the student can solve them outside class hours. The objective of these exercises is to reinforce the theoretical concepts so that they can apply them in a more practical environment. These problems are solved partially or totally in subsequent classes so that the student can check their progress in learning.
With the activities carried out during the teaching semester, students acquire the necessary knowledge to face the final theoretical exam of the course, which is based on solving a challenge in which students will apply the latest technologies used by telecommunications operators that they have learned in class.
The assessment of the course is based on continuous assessment and a final theoretical exam.
The final grade will be the best of the following options:
- 70% assignments + 30% tests
- 40% final exam + 50% assignments + 10% tests
- 100% final exam
Assignments, tests and the final exam are all passed with a grade of 5 out of 10.
To pass the course, it is necessary to obtain a minimum final grade of 5 out of 10 in any of the three calculation options. In the extraordinary examination period in July, the grade will depend only on the extraordinary exam, which will not be averaged with the submitted assignments or the course tests.
The following will be assessed:
- The understanding of the fundamental concepts related to broadband networks and the technologies used by operators.
- The ability to analyse and apply the concept of Quality of Service in different network environments.
- The correct identification and understanding of the main architectures and technologies covered in the course.
- The ability to apply theoretical knowledge to the resolution of tests, exercises and assignments.
- Conceptual and terminological rigour in the use of the language specific to telecommunications and networks.
- Clarity, coherence and correctness in the presentation of the proposed answers and solutions.
