HSPA is a proven mobile broadband technology that is already deployed in over 100 commercial networks. It is built on the firm foundation of the 3GPP family, offering the carrier-grade voice services users expect and the broadband speeds they desire.
HSPA can be built out using the existing GSM radio network sites and is a software upgrade of the installed W-CDMA networks.
Together with dual-mode terminals, this ensures nationwide coverage both for voice (GSM/W-CDMA) and data (HSPA/EDGE).
For operators, technology choices made now will influence operations for many years to come. 3GSM technologies are the future proof choice -- from an initial investment standpoint, economies of scale and the ability to extend and continuously enhance the solution.
