Agenda – A Heuristic Approach

WCDMA Tester Product Requirements

I: Lucent experience (Network Equipment) II: Wiscom Tech experience (mobile terminal) III-IIII:ITRI, III experience (Baseband, protocol) V-VI: Customer experience (operators,

manufacturers)

WCDMA Tester Product Challenges Meet the Challenges

The fourth year SysAir venture experience

Requirement I : Network Simulator is not Network Equipment!

We can not afford Over-Engineering the product

  • 1996-2000: WCDMA BTS and RNC Product design
  • 80 millions annual investment from Lucent, 16 millions from

DoCoMo

BTS RNC

Requirement I I : Understand 3G mobile terminal Test Criteria

We can not afford test mobile initially

  • 2000-2001 of Wiscom Tech:

WCDMA BB HW and air interface protocol design

  • 10 millions investment from

AMD, and Wall Street, 30 staffs

  • IPR acquired by INTEL

Requirement III: Network Simulator is much more than a UMTS/WCDMA simulation (Neither MATLAB or OPNET is a suitable product platform )

UE PHY,MAC, RLC

MATLAB, OPNET are good simulation tools, but not suitable for product software realization

  • 1. TTCN tool expensive
  • 2. Test mobile expensive
  • 3. Test Tool integration

requires more resource than small company can handle Thin RRC: UE L1C (TS 34.108 Scenarios) Configuration CODEC: TS 34.108 CPHY, CMAC,CRLC Challenge II:

  • 1. ASN.1 tool expensive
  • 2. RRC CODEC

extremely complex

  • 3. Test SW Platform

(MATLAB is too slow)
