Abstract :
We investigate the impact of mobility on UMTS network planning, which stems from (i) the higher SIR requirements that apply in case of higher velocities; and (ii) the greater radio resource reservation regarding handovers that is required in case of higher velocities, in order to keep the dropping probability below a prespecified target value; as a consequence, fresh call blocking increases, inducing a need for denser site planning. A computationally inexpensive yet for planning purposes sufficiently realistic analytical approach is presented to evaluate the impact of both mobility-related aspects on network planning and performance
