Abstract
The broadband multimedia Communications over wireless channel is a very important research issue. There has been a lot of research done in this domain. One of the main issues will be the implementation of access networks that are able to connect every potential user to the core broadband network. Nowadays developed access systems do(or under development) belong to two categories: wired and wireless systems. The wired ones use coax cable and optical fiber and are classified, according to their topology and network extension, as: HFC (Hybrid Fiber Coax); FTTC (Fiber to the Curb/Building) FTTH (Fiber To The Home). The main limits of the wired systems are low flexibility and high installation cost. This has been seen e.g. in the slow emergence of local fiber access points. The wired network structure will be important as the core network for advanced video surveillance (AVS) systems.
