Abstract

Passive distribuerede antennesystemer (DASs) bestående af distribuerede antennefødeledninger eller punktantenner er efterhånden velkendte i større kontorbygninger, hvor de giver en effektiv dækning. Mere sofistikerede DASs med intelligent kanalgenbrug og muligheden for at adaptere til varierende interferens- og trafik-situationer er mindre udbredte til trods for deres potentiale for øget trafikkapacitet i sammenligning med traditionelle (pico-) cellulære koncepter. I dette kapitel gennemgås et studie af et konkret indendørs miljø hvor de faktiske udbredelsesforhold tages i betragtning i evalueringen af kapacitetspotentialet for et adaptivt DAS. Efter en introduktion fortsættes med en beskrivelse af indendørsmiljøet, herunder modeller for udbredelsestab og brugermobilitet der senere lægges til grund for simulering. Radioressource håndteringen beskrives ved algoritmer for allokering af transmissionseffekt og radiotilgangspunkt, sammen med algoritmer for dynamisk kanalallokering. Efter en kort gennemgang af simuleringsantagelserne gives der en kapacitetssammenligning mellem det adaptive DAS og et system med foruddefineret allokering for kanal- og radiotilgang. Kapitlet afsluttes med en diskussion af resultaterne og et par udestående punkter for anvendelsen af DASs i indendørs miljøer.
