HSPA & HSPA+
HSPA is the next level of DATA mobile after the GPRS and EDGE networks. HSPA, an abbreviation of ‘High-Speed Packet Access’ is a join of two technologies, one used for the downlink and other for the uplink that can be built onto any 3G UMTS or W-CDMA technology to increase the data transfer speeds.
In both cases, WCDMA and HSPA segment the same network and use site base station antennas to serve users. The upgrade WCDMA HSPA requires new feature on the network and potentially the swap of some new equipment into the base station and RNC to support the required higher data capacity.
