OULU, Finland -- The NetHawk RNC/Iub Simulator allows NodeB developers to test, verify, anddemonstrate NodeB implementation in labs and at their customers’ premises.HSDPA is a key feature for UMTS operators. The NetHawk RNC/Iub Simulatorsupports testing of this high capacity feature. The new NetHawk RNC/Iub Simulatorversion 1.3 introduces four major test applications for NodeB development andpromotions:

  • BER Tester for HSDPA 5.3 Mbps

  • 3GPP 25.141 test models for NodeB conformance testing

  • internal IP gateway for HSDPA demonstrations

  • virtual Iub™ option.



The technical enablers of these applications are new 3GPP Release 5 encoders anddecoders, support for asymmetric DCH channels, significant improvement in L1capacity, support for 2 ms TTI, and accurate synchronization of the NetHawk N3Adapter.The NetHawk RNC/Iub Simulator supports release 99, release 4 and now also release5 baseline in NBAP and RRC protocols that specify HSDPA functionality:

  • 3GPP Release 99, March 2002

  • 3GPP Release 5, September 2003

  • HSDPA Layer1 5.3 Mbps

  • NBAP 3GPP, Nokia, Ericsson and Alcatel variants.



Simulator supports asymmetric DCH up to 3.6 Mbps in downlink channels and 64kbps in uplink channels.

The virtual Iub option allows the script development in a workstation without cabling orIub-related hardware. Virtual Iub also eliminates the uncertainty of a real-time RANenvironment and frees up the busy NodeB testing environments.
