Analyze Assure Accelerate TM HSDPA Roadmap

Analyze Assure Accelerate TM SR3420 WCDMA Network Emulator SR3420 is a new WCDMA network emulator platform designed specifically for HSDPA (and beyond …) Significant signal processing resources and high fidelity RF design enables a rich roadmap of field upgradeable features  Initial HSDPA release (Phase 1) will support 3.6Mbps  Future releases: 14Mbps Advanced scheduler algorithms, dummy-user traffic profiles HSDPA mobility testing Enhanced uplink (EU-DCH)

Analyze Assure Accelerate TM SR3420 Roadmap July 2005  Pre-release of AirAccess-HSDPA Full call processing and support for 1.8 Mbps (Cat 12) September 2005  Phase 1 Commercial release of AirAccess-HSDPA Single cell support for 3.6 Mbps (Cat 6) with R99 backwards compatibility Controllable MAC-hs Throughput and CQI statistics Fixed Reference Channels (FRC) Section 9 “manual mode” testing

Analyze Assure Accelerate TM SR3420 Roadmap December 2005  U-ATS release for Section 9 1H2006  Phase 2 Commercial release for AirAccess-HSDPA Single cell HSDPA with multi-cell, multi-carrier R99 (all within one instrument) Support for 14 Mbps (Cat 10) Advanced mobility testing (HS ↔ HS intra and inter NodeB handovers, HS ↔ R99) Configurable scheduler Dynamic cell loading for HS and DCH Support full validation of Section 9
