UMTS Radio Interface Field Measurements
Kai M. Ojala, Pasi Niemi · Kluwer Academic Publishers eBooks · 2006
In this chapter, the main WCDMA field measurements are described. Measurements are divided into three categories: measurements in idle mode, in connection establishment, and in connected mode. Measured parameters in these modes are explained with examples. Once WCDMA is new technology, new features and functionalities will have to be verified. In the beginning, coverage, power control, and soft handovers are the key issues as well as verification of different connection types provided by a WCDMA system. At the start of the 3G era, WCDMA coverage is not continuous, so inter-working with GSM/GPRS has to work as well, so that customers can access cellular services continuously. WCDMA is intended for various applications besides voice services: the testing of circuit switched and packet switched data in the field is described as well as the testing of applications that run on top of the packet switched or circuit switched connection.
