The TM500 test mobile platform is the industry standard for HSDPA infrastructure development and test. The HSUPA options, consisting of Layer 1/Layer 2 and Higher Layer Protocol functionality, extend these features to include the latest 3GPP Enhanced Uplink technology, allowing detailed testing and analysis of complex packet-based services and applications.

• Full Layer 1 / Layer 2 implementation of 3GPP Enhanced Uplink features
• Full support of HSUPA and HSDPA all UE capability classes
• Simultaneous HSUPA and HSDPA operation at maximum data rates of 5.76Mbps and 13.97Mbps respectively
• Flexible configuration of HSUPA, HSDPA and R99 functionality including Soft Handover and Scheduled / Non-Scheduled data services
• Innovative test features to assist Node B / RNC development and regression test
• Optional Release 6 Layer 3 and NAS functionality to provide full protocol capabilities for system test

Targeting uplink data capacity
High Speed Uplink Packet Access (HSUPA) provides a major enhancement to the 3GPP roadmap. HSDPA-capable systems enable advanced services and high data rates in the downlink, HSUPA seeks to eliminate the bottleneck that is now present for uplink services. In a similar way to the downlink HSDPA technology, HSUPA offers enhanced uplink performance and spectrum utilization in conjunction with packet switched technology. High uplink data rates and reduced packet latencies are achieved using enhancements including 2ms TTI packet data, HARQ and Node B scheduling. Using multi-code techniques, HSUPA offers uplink data rates of up to 5.76 Mbps.

Innovative 3G Test and Analysis
The TM500 HSUPA is ideal for the infrastructure design, development and test engineer. A wide range of test modes and features are provided to assist the user in a structured development and test program. Test modes allow detailed analysis of Layer 1 and Layer 2 functionality and permit uplink and downlink physical channels to be verified and validated independently. The effects and operation of soft handover can also be monitored in detail.

The TM500 HSUPA Higher Layers option extends the features of the TM500 for use in full system test. In addition to full protocol support of Release 6 HSUPA features at Layer 3 and NAS, the option provides enhanced logging including full ASN.1 decode of all Release 6 RRC PDUs. The TM500 can be configured to support different HSUPA, HSDPA and R99 UE categories, enabling extensive system testing long before high data rate commercial mobiles are available.
