As an upgrade to an operator’s Universal Mobile Telecommunications (UMTS) network, HSxPA (high speed packet access, an evolution of the UMTS standard) offers higher data transfer rates and improved network capacity. However, in order to achieve these improvements, HSxPA introduces more complexity at the edge of the network—at the radio link that forms the boundary between the network operator’s own infrastructure and their customers’ mobile user equipment.


This paper explains why widespread adoption of user equipment that provides Type-3 advanced receiver performance is essential for operators seeking to achieve the highest revenue and lowest operating costs for their HSxPA networks. It introduces Icera’s superior Type-3 advanced receiver architecture that uses an “adaptive wireless” approach that continually optimizes modem performance for changing radio conditions.
