Abstract :
Performance analyses of in building distributed antenna (DA) systems for W-CDMA are presented. Uplink and downlink outage probabilities are related to the transmitted power, the shadowing statistics and the loading of the cell and it is observed that by deploying DA in a multi-floor environment the advantages in terms of both coverage and capacity are significant. However, capacity limitations are present due to the noise rise of home cell power controlled interferers, which give rise over thermal noise. In order to overcome these limitations two more flexible architectures, namely zoning and switching, are presented and compared.
