This paper presents the design patterns and architecture of a testbed for the evaluation of Quality of Service (QoS) provisioning in WCDMA (Wideband Code Division Multiple Access) based third generation wireless networks. The testbed allows for the evaluation of QoS adaptation techniques that supercedes to the traditional power control in the Radio Resource Manager (RRM); it handles classes of service defined for the Universal Mobile Telecommunication System (UMTS), as well as mobility and handoffs. The main focus of this paper is the testbed itself, the underlying assumptions including those related to the physical layer, the user defined parameters, and the various measurements and ratios gathered for the evaluation of QoS provisioning strategies. The testbed has been used to evaluate the performance of QoS adaptation algorithms under a variety of admission strategies and load scenarios. The performance results of these QoS adaptation strategies will be given in a separate paper.
