With mobile broadband data usage growing at a rapid pace, mobile operators are struggling to support the increased bandwidth requirements of these services. Faced with capacity bottlenecks in their existing 2.5G/3G packet cores, operators are confronted with the following choice: upgrade their existing network infrastructure to a more current Wideband Code Division Multiple Access/High Speed Packet Access (W-CDMA/HSPA+) release or, if spectrum is available, move to a new Long Term Evolution (LTE) network. In either case, it is unlikely that existing 2.5G/3G packet cores can deliver a cost-effective upgrade that meets the more demanding requirements of either HSPA+ or LTE. However, there is a solution that supports both options.
