More and more HSDPA or High Speed Downlink Packet Access networks are appearing, and the reason is clear. The incremental UMTS upgrade aims to increase user peak data rates - much like EDGE has done for 2G. HSDPA theoretically offers peak downlink data rates of up to 14 Mbps - dramatically more than the 384 kbps that is typical of today's UMTS. In the real world, QVoice users have already measured results in excess of 1.2Mbps; devices capable of 3.6Mbps are expected to hit the market in summer 2006.
Like other radio technologies, HSDPA confronts the operator with some new challenges, but QVoice is ready to help by integrating even more HSDPA test functions in successive software releases.
Appearing already last year in QVoice Release 4.5 was the full support of HSDPA data cards based on Qualcomm chipsets MSM6275, which

included the Sierra Wireless Air Card 850, Novatel Merlin U740 and the Option Globetrotter 3+ for QoS IP data testing. All known IP tests are functional and all application level KPIs, such as throughput and round trip time are measured and reported by QVoice. In the next QVoice Release 5.0, testing capabilities will be expanded including HSDPA specific full engineering trace for RF parameters and Layer 3 messages etc. for both real-time analysis in the field and detailed post processing in the office.
QVoice will be helping operators deliver HSDPA quality services, while HSDPA itself will be helping 3G technology fulfill its promise of higher performance.
