Description
Summary:This paper looks at a new method of handling the expected traffic fluctuation in a microcellular and picocellular environment. The bunch concept, which is introduced in the UMTS proposal, is investigated under various traffic conditions. Its performance in traffic hot-spots is compared to that of a conventional microcellular network. The results show that the outage probability is dramatically reduced with the use of distributed antennas. The use of distributed antennas in the bunch concept also increases the capacity. With 8 extra antennas covering the same area as one basestation, the capacity can be increased by as much as 400 %.
