Abstract
This thesis designs the access network for a new IT infrastructure in Denmark's Region of Nordjylland, using WiMAX as the short-term access technology and as a complement to future FTTH. It begins with an overview of broadband wireless and WiMAX, then analyzes the region's geography and population projections to clarify demand and constraints. A step-by-step method is developed for base-station placement, frequency planning, traffic estimation, and budgeting, guided by requirements for more than 95% coverage of network terminals, scalability, balanced load, and cost effectiveness. The method incorporates propagation and spectrum considerations, regulatory options, and practical siting factors, and is formulated to be reusable in other areas. Applied to Nordjylland, it yields a proposed set of base-station locations, an associated frequency plan, indicative traffic profiles per site, and an investment projection for deployment. Detailed performance results and exact figures are not included in the excerpt.
Dette speciale designer adgangsnettet til en ny IT-infrastruktur i Region Nordjylland med WiMAX som kortsigtet adgangsteknologi og som supplement til fremtidig FTTH. Arbejdet indleder med et overblik over bredbåndstrådløse net og WiMAX og analyserer derefter regionens geografi og befolkningsprognoser for at belyse behov og rammevilkår. En trinvis metode udvikles til placering af basestationer, frekvensplanlægning, trafikestimering og budgettering, styret af krav om mere end 95% dækning af netværksterminaler, skalerbarhed, balanceret belastning og omkostningseffektivitet. Metoden indarbejder udbredelses- og spektrumforhold, regulative muligheder og praktiske placeringsfaktorer og er formuleret, så den kan genbruges i andre områder. Anvendt på Nordjylland munder den ud i et forslag til basestationsplaceringer, en tilhørende frekvensplan, vejledende trafikprofiler pr. station og en investeringsfremskrivning for udrulning. Uddraget indeholder ikke detaljerede resultater eller tal.
