A Case Study on Distributed Antenna Systems

Research output: Contribution to book/anthology/report/conference proceedingBook chapterResearch


Passive distributed antenna systems (DASs) consisting of distributed feeder lines or single point antennas are now often installed in large office buildings where they provide efficient coverage throughout the building. More sophisticated DASs with intelligent reuse and the ability to adapt to changing interference and traffic conditions are less common, despite their potential for increased capacity in comparison with traditional (pico)cellular based concepts. This chapter explores a case study of one indoor environment where the site-specific propagation characteristics are taken into account in evaluating the capacity potential from adaptive DASs. After an introduction, the chapter gives a description of the site-specific environment considered in this study, including models for the large-scale path loss and user deployment that is later assumed for simulations. Radio resource assignment is described in terms of algorithms for power allocation and access port assignment, as well as algorithms for (dynamic) channel assignment. After an outline of simulation assumptions, system capacity comparisons are given between the adaptive DAS and a system with fixed channel and access port assignment. The chapter is concluded with a discussion on the results and some open issues for deploying DASs in the indoor environment.
