Interactions among UMTS microcells and macrocells supporting data traffic in a real airport scenario

This paper analyses a solution to provide UMTS coverage in a real airport scenario by reusing the existing GSM infrastructure. In this case, macrocell and microcell layers are highly decoupled in terms of interference, so it is shown that CPICH power adjustment does not play a significant role in interlayer traffic distribution. On the other hand, with respect to in-building coverage, it has been observed that by reducing the number of repeaters per microcell an increase in capacity can be obtained.
