This paper is concerned with optimization of distributed broadband wirelesscommunication (BWC) systems. BWC systems contain a distributed antenna system(DAS) connected to a base station with optical fiber. Distributed BWC systemshave been proposed as a solution to the power constraint problem in traditionalcellular networks. So far, the research on BWC systems have advanced on twoseparate tracks, the design of the system to meet the quality of servicerequirements (QoS) and optimization of the location of the DAS. In this paper,we consider a combined optimization of BWC systems. We consider uplinkcommunications in distributed BWC systems with multiple levels of prioritytraffic with arrivals and departures forming renewal processes. We develop ananalysis that determines packet delay violation probability for each prioritylevel as a function of the outage probability of the DAS through theapplication of results from renewal theory. Then, we determine the optimallocations of the antennas that minimize the antenna outage probability. We alsostudy the tradeoff between the packet delay violation probability and packetloss probability. This work will be helpful in the designing of the distributedBWC systems.
