Communications Networks and Services and Switching

This course describes the principles of Networks with wireless access technologies, and the implications that the special features that this type of access (for example, mobility of users) have in the network protocols. 4G and its evolution (5G), and the technology IEEE 802.11 (WiFi) will be analysed. To achieve this objective, the student must acquire specific knowledge and capacities. Regarding the Program Outcomes (POs) of the degree, the course covers the following ones: a) an ability to apply knowledge of mathematics, statistics, science, telecommunication technologies and engineering b) an ability to design and conduct experiments, as well as to analyze and interpret data j) a knowledge of contemporary issues k) an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice Regarding knowledge (PO j), at the end of the course the student will be able to: - Understand the specific characteristics of the wireless access and the impact of mobility. - Understand the standards IEEE 802.11, including aspects related to QoS and security. - Understand the 4G: standardization process, architecture, protocols, and service provisioning. - Understand the future architecture of the mobile networks: EPS. - Understand the future 5G networks and the relevant technologies (virtualization, C-RAN and MEC). SPECIFIC CAPACITIES: - Work with the main technologies in the field of mobile communication networks, understanding their components and functionalities (PO j). - Design and configure mobility solutions in IP networks to support a group of mobile users (POs a, k). - Configure equipment based on IEEE 802.11 technologies, understanding advanced configuration options (POs b, k). - Design and configure a wireless access solution to support mobile users (PO b). - Design cellular communications networks architectures (PO a).

This is a wireless and mobile communications course, which covers and analyzes the implications that the particular characteristics of these types of networks have on the different protocols used in the networks. The programme is divided into 3 parts: PART ONE (Introduction): Introduces the problem of wireless networks and gives a brief introduction to the physical layer. PART TWO (WiFi): Introduction to the IEEE 802.11 specification family. Control of access to the medium in IEEE 802.11. Advanced technologies in IEEE 802.11. PART THREE (4G): Introduction to the 4G system and its evolution towards 5G.

The teaching methodology includes: (1) Theoretical classes. Students will be provided with the learning objectives to be covered in which lecture and the specific material to prepare it (prior to the actual class). In these classes, the concepts related to the learning objectives are revised and, with the participation of the students, the acquired knowledge will be checked and strengthened interactively (POs a, j). (2) Laboratory classes in computer rooms, where students will configure wireless communication nodes with mobility support, and also end devices. Using traffic supervision tools, students will also analyze the proper operation of the protocols (POs b, k). (3) Exercise solving by the students, which will help them to auto-assess their level of knowledge and acquire the necessary abilities (PO k). (4) In-class solution comparison and joint correction to the exercises, which should help to strengthen knowledge and develop the ability of analyze and communicate the information that is relevant in order to solve problems (POs b, k). (5) Optionally, the student may carry out a technology development project on IEEE 802.11 or 4G.
