Module Objective

The course aims at presenting and analyzing the main technologies of wireless and wired broadband networks. More specifically, the architectures of wireless broadband 3G networks (3G-UMTS) and 4th Generation (4G-LTE), after presenting the precursors of the second and intermediate generation (2G-GSM / 2.5G-GPRS) are studied. It also presents the most important protocol (IEEE 802.11) wireless local broadband networks (WLAN) and architectures IEEE 802.16d and 802.16e of WiMAX for wireless broadband coverage of wider geographic area, whereas modern broadband trends with Radio-over- networks Fiber (RoF) are presented. Finally, presents the technologies of wired broadband ATM networks, MPLS, DSL, SONET / SDH, WDM / DWDM, and the most common packet scheduling algorithms used in ATM switches, broadband networks (such as PIM, iRRM, SLIP, iSLIP, DRRM).

Module Description

This course aims to present and analyze the most important technologies of wireless and fixed broadband networks. Specifically, it presents and analyzes the corresponding network architectures of Wireless Broadband Networks 3G (UMTS) and 4G (LTE), after presenting the corresponding legacy Systems 2G (GSM) and 2.5G (GPRS). Furthermore, the most important protocol (i.e., IEEE 802.11) for medium access in Wireless Local Area Networks, the corresponding protocols for Wireless Metropolitan Area Networks (i.e., ΙΕΕΕ 802.16d and 802.16e of WiMAX) as well as the current trend of Radio-over-Fiber networks are presented and analyzed in detail. Finally, the corresponding fixed technologies in broadband networks, such as ATM, MPLS, DSL, SONET/SDH, WDM/DWDM as well as the most used scheduling algorithms in ATM switches (such as PIM, iRRM, SLIP, iSLIP, DRRM) are presented and evaluated.
