Wireless Networks

Description
During the course, the main techniques of transmission and multiplexing of users in a mobile radio channel are reviewed. This study is carried out from 3 angles: public or private systems, cellular systems or ad hoc networks and finally networks aimed at voice communications or purely data networks, all of them wireless. All these concepts are explained first by looking at the theoretical part of communication and then moving on to see how we implement it, specifically by studying each of the most representative standards in each of the different applications and generations. To cite a few examples we will see the 2G / 3G / 4G and 5G telephony standards as public cellular systems, closed user group systems and trunking as private systems, WLAN networks based on the IEEE 802.11a/b/g for the transmission of data on private medium-range networks (WiFi), and Bluetooth networks for short-range personal communications and IoT standards. Finally, add that although the subject focuses on the theory of communications on the radio interface, also study in detail the other parts involved in any communication network such as the necessary transport and switching network, control elements. and supervision, capacity and coverage calculations, etc.

Previous Knowledge

Concepts of Signals, Transmission Systems and Telematics.

Objectives

The subject provides students with the following learning outcomes (the degree courses on which they appear are provided in brackets):

- To know and put into practice the main concepts of the wireless systems and networks (GC).
- To know and put into practice the main concepts of the wireless networks (GT).

Other objectives of the course are:

1. To learn the basic knowledge of mobile communication systems, its classification and most important characteristics.
2. The capacity to link this knowledge with the contents of other subjects where similar aspects are explained.
3. The ability to understand and learn English papers dealing with mobile communication systems.
4. The ability to work as a team to solve a problem where a real situation is considered.
5. The capacity for oral and written communication in the native language.

Contents

The subject is divided into three thematic units:

1. Mission critical systems, where alternatives to deploy corporate networks of closed user groups are studied.
2. Communications in licensed bands for public use, where mobile phone standards currently available are studied.
3. Communications in non-licensed bands, where design possibilities in free bands are studied.

1. Mission critical systems
1.1 System components
1.2 Design and calculations
1.3 Mission critical tecnologies: PMR, DMR, TETRA, LTE-PRO

2. Communications in bands licensed for public use
2.1 Global System for Mobile Communication (GSM)
2.2 Evolutions of the GSM: GPRS, HSCSD, EDGE
2.3 Universal Mobile Telecommunication Service (UMTS)
2.4 UMTS Evolutions (HSPA)
2.5 Long Term Evolution (LTE)
2.6 5G systems

3. Communications in non-licensed bands
3.1 Wireless Local Area Network (WLAN): Wi-Fi
3.2 Radiofrequency Identification. (RFID)
3.3 Wireless Personal Area Network (WPAN): Bluetooth, Zigbee, UWB
3.4 Standards for IoT (Internet of Things). LoRaWan, SigFox

Methodology

The methodology and didactic instruments used are the following:

- Class presentation on the concepts and procedures associated with the module, using the methods applied in the lesson
- Individual study and Project work
- Assessment activities

The subject is taught once a week, in a single session of 2.5 hours. For each of the 3 thematic blocks of the subject, a design case is proposed that students will have to solve in groups. Each session consists of a theoretical explanation and practical work on the case of design. Individual exams will also be performed at the end of each of the 3 blocks to guarantee the individual achievement of the knowledge on the part of each student.

Evaluation

The assessment activities of the subject are:

- Exams
- Exercises and tests in class
- Participation in class
- Individual work or group work

The subject is divided into 3 clearly differentiated thematic blocks:

- Mission critical systems
- Licensed bands for public use
- Non-licensed bands

For each block a design case is proposed that students will have to solve in groups of two people and an individual examination. The final grade of each block is calculated as the average of the work note and the individual exam. The final grade of the subject is the arithmetic mean of the 3 partial notes, as long as each of them is greater than 5.

Both the practical work and the test are highly significant evaluation activities, according to the copy regulations available at https://www.salleurl.edu/en/normativa-de-copies.

In case of having to recover any of the parties, there will be an extraordinary call in July.
