On the UMTS Downlink Capacity in (Open Rural and Countryside) Zone Near Deep Space Network (DSN) Installations

Abstract

The UMTS macrocell downlink capacity is evaluated for macrocells that operate at the same frequency as the Deep Space Network (DSN) and that are nearby the DSN installations. It has been found that the cell capacity is not affected when the distance between the DSN installations and the macrocell is more than 21 km. For lower distance, the effect is high and the downlink vanishes at a distance less than 2 km when the microcell radius is 1 km. Near the DSN installation, the macrocell radius has to be 1 km or less.
