Interference management in UMTS femtocells ("low-band")

This paper considers the interactions between macro and femto radio layers, how can they be managed, and what this implies for the technology, the operator and the consumer.  It is concerned primarily with the 850 MHz band in the United States, but is equally applicable to the 900 MHz band in Europe and elsewhere. The paper explicitly  “stands on the shoulders of giants”, drawing on the great mass of study work that has already been undertaken by 3GPP RAN4 participants in analysing these issues, and referencing them for further reading.
