| Popis: | Trådløse kommunikationssystemer er dynamisk af natur, som kommer fra flere faktorer, nemlig: Radioudbredelse handicap, trafik ændringer, interferens betingelser, bruger mobilitet osv. i et heterogent miljø, de dynamiske netværk adfærd kræver en dynamisk styring af radio-ressourcer , en proces, der forbinder en lang række parametre og kvalitet / resultatindikatorer, der skal fastsættes, måles, analyseres og optimeres. Radio-over-fiber (ROF) teknologi indebærer anvendelse af optiske fiber forbindelser til at distribuere radiofrekvens (RF) signaler fra et centralt sted for fjernadgang enheder (raus). For at øge radio dækning og kapacitet, dette dokument foreslås der en radio ressource management (HRM) ramme, der udnytter en ROF centraliseret topologi og kan tjene en lang række forskelligartede raus. Den foreslåede ramme er beskrevet i form af fysiske og logiske enheder og deres samspil. Wireless communication systems are dynamic by nature, which comes from several factors, namely: radio propagation impairments, traffic changes, interference conditions, user mobility, etc. In a heterogeneous environment, , the dynamic network behavior calls for a dynamic management of the radio resources; a process that associates a large number of parameters and quality/performance indicators that need to be set, measured, analyzed, and optimized. Radio-over-fiber (RoF) technology involves the use of optical fiber links to distribute radio frequency (RF) signals from a central location to remote access units (RAUs). In order to increase the radio coverage and capacity, this paper proposes a radio resource management (RRM) framework that takes advantage of an RoF centralized topology and can serve a large number of heterogeneous RAUs. The proposed framework is described in terms of physical and logical entities and their interactions. |
