1 HSDPA Radio Network Controller for HSDPA HSDPA High Speed Downlink Packet AccessW-CDMA 14.4 Mbps RNCHSDPA HSDPA Abstract High Speed Downlink Packet Access (HSDPA) technology provides a maximum data transfer rate of 14.4 Mbps for packet downlink channels of wireless access networks that use Wideband Code Division Multiple Access (W-CDMA). This technology enables a wider range of services to be offered. This paper outlines the application of HSDPA in radio network controllers (RNCs), which are the management nodes of wireless access networks, and describes how HSDPA efficiently transmits data. It also describes how HSDPA makes it possible to effectively and efficiently control an entire wireless access network, including its voice and packet data. 106 FUJITSU.58, 2, p (03,2007)
