Expand Interference Management and Performance Analysis of UMTS/HSPA+ Femtocells
Abstract: Femtocells are low-power cellular base stations that operate in licensed spectrum. They are typically deployed indoors to improve coverage and provide excellent user experience, including high data rates. Cellular operators benefit from reduced infrastructure and operational expenses for capacity upgrades and coverage improvements.

Expand Impact of SIB Scheduling on the Standby Battery Life of Mobile Devices in UMTS
Abstract—The UMTS standard for third generation wireless communications specifies several parameters that play a role in the tradeoff between the performance and the battery life of mobile devices. There are also other, non-standardized, implementation-specific mechanisms that affect both the performance as well as the battery life.
