DESCRIPTION
The course covers the physical and the link layer of the OSI and TCP/IP protocol stacks. It provides and introduction to telecommunication systems analysis and design and analyses the most popular technologies of the physical and link layer.
STRUCTURE
The course is made of three main topics. The first topic is an introduction to the basic principles of Telecommunications and includes protocol architecture and layering (OSI/ISO), standardization and types of networks. The second part examines data transmission, analog and digital signals and physical media and the third part considers LAN technologies including Ethernet, IEEE 802.11x (Wi-Fi) and medium access (CSMA/CD) .
