Radio network modeling and performance evaluation for UMTS
We review the foundations of radio communication and introduce the classical static approach to performance evaluation for umts; this provides the starting point for the subsequent developments. We first outline the general structure of cellular wireless communication networks and the special nature of the radio channel in Sec. 2.1. In Sec. 2.2, we explain the principles upon which communication over the umts radio interface is built, as well as their implementation in the standard. The available methods for umts radio network performance evaluation are briefly discussed in Sec. 2.3. We introduce the classical static model of the umts radio interface in Sec. 2.4; it is used in the remainder of this thesis. Its role in the evaluation of a expected radio network performance by static simulation is detailed in Sec. 2.5, which throws into relief the complexity of classical performance evaluation for umts.

- 2.The main spectrum for w-cdma fdd is allocated at 1920–1980 MHz (ul) and 2110–2170 MHz (dl) in Europe and most of Asia. In other parts of the world, the allocated frequencies vary; in the US, notably, lower frequencies in the 824–960 MHz band occur (Holma & Toskala, 2001, Ch. 1).Google Scholar
